3D Printing

3D Printing is also known as additive manufacturing, refers to various processes used to synthesize a three-dimensional object. In three d printing, successive layers of material are formed under computer control to create an object. These objects can be of almost any shape or geometry and are produced from a 3D Model or other electronic data source. A 3D printer is a type of industrial robot.

3D Printer Front View 3D Scanner is a device that analyses a real-world object or environment to collect data on its shape and possibly its appearance (e.g. colour). The collected data can then be used to construct digital three-dimensional models. 2D.

3D Modeling is the process of developing a mathematical representation of any three-dimensional surface of an object, either inanimate or living, via specialized software.

3D Printing Processes available tend to be additive in nature with a few key differences in the technologies and the materials used in this process. Some of the different types of physical transformations which are used in 3D printing include melt extrusion, light polymerization, continuous liquid interface production and sintering.

3D Light Printer - 3D Printing with Light

3D Printing is not a disruptive innovation, it's more of a productive innovation that offers more options and more convenience. 3D printing is like small farms. Small farms make a big difference, but not in the same way as big farms do. We need small farms, but we also need some big farms too.

Volumetric Printing is a three-dimensional digital-to-physical imaging technology developed in 2013 that uses ink or other pigments suspended in a volume to form a full-color volumetric scene in physical space. It is a static version of volumetric display. Volumetric prints are auto-stereoscopic, full parallax (in both horizontal and vertical viewing arrangements) and can be viewed by multiple viewers in regular room lighting. A volumetric print can be thought of as a reconstructed light field based on the scattering of light by distributed pigments in volume. Any three-dimensional scene can be volumetrically printed, although biological specimens and volumetrically X-rayed objects (i.e., CT scans) are thought to be particularly well suited to this type of imaging. There are several methods for producing a volumetric print, the most common being an index-matched stack of hundreds of sheets of thin clear material (most often PMMA, also known as Lucite or acrylic). Each sheet in the volumetric stack is printed with a color slice of a digital 3D model, placed in a vacuum chamber, and then injected with a fluid matching the index of refraction of the sheet material. Volumetric printing has been called "Hologram 2.0" by a company marketing the technology. Volumetric prints however are not produced in the same manner as holograms, in that there is no interference pattern generated or used in basic volumetric prints.

Topology Optimization is a mathematical method that optimizes material layout within a given design space, for a given set of loads, boundary conditions and constraints with the goal of maximizing the performance of the system. TO is different from shape optimization and sizing optimization in the sense that the design can attain any shape within the design space, instead of dealing with predefined configurations. The conventional TO formulation uses a finite element method (FEM) to evaluate the design performance. The design is optimized using either gradient-based mathematical programming techniques such as the optimality criteria algorithm and the method of moving asymptotes or non gradient-based algorithms such as genetic algorithms. Topology Optimization has a wide range of applications in aerospace, mechanical, bio-chemical and civil engineering. Currently, engineers mostly use TO at the concept level of a design process. Due to the free forms that naturally occur, the result is often difficult to manufacture. For that reason the result emerging from TO is often fine-tuned for manufacturability. Adding constraints to the formulation in order to increase the manufacturability is an active field of research. In some cases results from TO can be directly manufactured using additive manufacturing; TO is thus a key part of design for additive manufacturing.

Shape Optimization is part of the field of optimal control theory. The typical problem is to find the shape which is optimal in that it minimizes a certain cost functional while satisfying given constraints. In many cases, the functional being solved depends on the solution of a given partial differential equation defined on the variable domain.

Voxel represents a value on a regular grid in three-dimensional space. As with pixels in a 2D bitmap, voxels themselves do not typically have their position (i.e. coordinates) explicitly encoded with their values. Instead, rendering systems infer the position of a voxel based upon its position relative to other voxels (i.e., its position in the data structure that makes up a single volumetric image). In contrast to pixels and voxels, polygons are often explicitly represented by the coordinates of their vertices (as points). A direct consequence of this difference is that polygons can efficiently represent simple 3D structures with much empty or homogeneously filled space, while voxels excel at representing regularly sampled spaces that are non-homogeneously filled. Voxels are frequently used in the visualization and analysis of medical and scientific data (e.g. GIS). Some volumetric displays use voxels to describe their resolution. For example, a cubic volumetric display might be able to show 512×512×512 voxels. The word voxel originated analogously to the word "pixel", with vo representing "volume" and el representing "element"; similar formations with el for "element" include the words "pixel" and "texel". One of the definitions is: "Voxel is an image of a three-dimensional space region limited by given sizes, which has its own nodal point coordinates in an accepted coordinate system, its own form, its own state parameter that indicates its belonging to some modeled object, and has properties of modeled region." This definition has the following advantage. If fixed voxel form is used within the whole model it is much easier to operate with voxel nodal points, i.e. three coordinates of this point. Yet, there is the simple form of record – indexes of the elements in the model set, i.e. integer coordinates. Model set elements in this case are state parameters, indicating voxel belonging to the modeled object or its separate parts, including their surfaces.

Boundary Value Problem is a differential equation together with a set of additional constraints, called the boundary conditions. A solution to a boundary value problem is a solution to the differential equation which also satisfies the boundary conditions.

Overprinting refers to the process of printing one color on top of another in reprographics. This is closely linked to the reprographic technique of 'trapping'. Another use of overprinting is to create a rich black (often regarded as a colour that is "blacker than black") by printing black over another dark colour.

Reprography is the reproduction of graphics through mechanical or electrical means, such as photography or xerography. Reprography is commonly used in catalogs and archives, as well as in the architectural, engineering, and construction industries.

The King of 3D printing materials? Polymaker PolyMax PC REVIEW (youtube)

Polycarbonate are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed. Because of these properties, polycarbonates find many applications. Polycarbonates do not have a unique resin identification code (RIC) and are identified as "Other", 7 on the RIC list. Upper working temperature: 115–130 °C (239–266 °F) / Lower working temperature: -40 °C (-40 °F) / Linear thermal expansion coefficient (a): 65–70 × 10-6/K / Heat deflection temperature: 0.45 MPa: 140 °C (284 °F); 1.8 MPa: 128–138 °C (262–280 °F) / Thermal conductivity (k) at 23 °C: 0.19–0.22 W/(m·K).

3D Print File Extension: STL Files are a standard file type that interfaces between Computer Aided Design (CAD) software and 3D printers. OBJ is an open file format that represents 3D geometry. VRML (or WRL) files are commonly used when a 3D model has color and you want to transfer that color to the print.

Stepper Motor is a brushless DC Electric Motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application in respect to torque and speed. Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.

Highest throughput 3D printer is the future of manufacturing. Rapid manufacturing on-demand could make parts-warehousing and expensive molds a thing of the past. Researchers have developed a new, futuristic 3D printer that is so big and so fast it can print an object the size of an adult human in just a couple of hours. The prototype HARP technology is 13-feet tall with a 2.5 square-foot print bed and can print about half a yard in an hour -- a record throughput for the 3D printing field. This means it can print single, large parts or many different small parts at once.

Avoiding Defects during Additive Manufacturing. Research reveals how pores form during metals additive manufacturing and become defects trapped in solidifying metal. The practical value of this research is that it can inform industry on how to predict and improve 3D printing processes. Laser powder bed fusion is a dominant additive manufacturing technology that has yet to reach its potential. The problem facing industry is that tiny bubbles or pores sometimes form during the printing process, and these pores create weak spots in finished products.

Additive manufacturing Algorithms Making new technology faster and cheaper. The software's algorithm automatically determines a part's sections and the sections' orientations. From this, the software designates when each section will be printed, and in which orientation within the printing sequence. The algorithm can help inform a designer's process plan to manufacture a part. It allows designers opportunities to make corrections or alter the design before printing, which can positively affect cost. The algorithm can also inform a designer how feasible a part may be to create using support-free manufacturing.

3D Printing from 2D Objects

Photogrammetry is the art and science of making measurements from photographs, especially for recovering the exact positions of surface points. Photogrammetric analysis may be applied to one photograph, or may use high-speed photography and remote sensing to detect, measure and record complex 2-D and 3-D motion fields by feeding measurements and imagery analysis into computational models in an attempt to successively estimate, with increasing accuracy, the actual, 3-D relative motions. From its beginning with the stereoplotters used to plot contour lines on topographic maps, it now has a very wide range of uses such as sonar, radar, and lidar.

Stereoplotter uses stereo photographs to determine elevations. It has been the primary method to plot contour lines on topographic maps since the 1930s.

Stereo-Lithography is a form of 3-D printing technology used for creating models, prototypes, patterns, and production parts in a layer by layer fashion using photopolymerization, a process by which light causes chains of molecules to link together, forming polymers, which are large molecules, or macromolecules, composed of many repeated subunits.

HARP or High-Area Rapid Printing, is a new technology that enables a record-breaking throughput that can manufacture products on demand. This means it can print single, large parts or many different small parts at once.

Computed Axial Lithography is a method for 3D printing based on computerized tomography scans to create objects from photo-curable resin. Computed axial lithography does not build models through depositing layers of material, as fused deposition modelling and stereolithography does, instead it creates objects using a series of 2D images projected onto a cylinder of resin. It is notable for its ability to build object much more quickly than other methods using resins and the ability to embed objects within the objects.

Image Plane is that plane in the world which is identified with the plane of the display monitor used to view the image that is being rendered. It is also referred to as screen space. If one makes the analogy of taking a photograph to rendering a 3D image, the surface of the film is the image plane. In this case, the viewing transformation is a projection that maps the world onto the image plane. A rectangular region of this plane, called the viewing window or viewport, maps to the monitor. This establishes the mapping between pixels on the monitor and points (or rather, rays) in the 3D world. The plane is not usually an actual geometric object in a 3D scene, but instead is usually a collection of target coordinates or dimensions that are used during the rasterization process so the final output can be displayed as intended on the physical screen. In optics, the image plane is the plane that contains the object's projected image, and lies beyond the back focal plane.

Graphics Pipeline is a conceptual model that describes what steps a graphics system needs to perform to render a 3D scene to a 2D screen.

Projection Plane is a type of view in which graphical projections from an object intersect. Projection planes are used often in descriptive geometry and graphical representation. A picture plane in perspective drawing is a type of projection plane. With perspective drawing, the lines of sight, or projection lines, between an object and a picture plane return to a vanishing point and are not parallel. With parallel projection the lines of sight from the object to the projection plane are parallel.

Parallel Projection is a projection of an object in three-dimensional space onto a fixed plane, known as the projection plane or image plane, where the rays, known as lines of sight or projection lines, are parallel to each other. It is a basic tool in descriptive geometry. The projection is called orthographic if the rays are perpendicular (orthogonal) to the image plane, and oblique or skew if they are not.

3D Printed Glass. 3D printing of chalcogenide glass could enable low-cost manufacturing of complex optical components for telecom and sensing applications. Chalcogenide Glass is a glass containing one or more chalcogens (sulfur, selenium and tellurium, but excluding oxygen). Such glasses are covalently bonded materials and may be classified as covalent network solids. Polonium is also a chalcogen but is not used because of its strong radioactivity. Chalcogenide materials behave rather differently from oxides, in particular their lower band gaps contribute to very dissimilar optical and electrical properties.

Cheap 3-D Printer can produce Self-Folding Materials.

3D Printed Tires and Shoes that Self-Repair. The material is manufactured using a 3D printing method that uses photopolymerization. This process uses light to solidify a liquid resin in a desired shape or geometry. To make it self-healable, they had to dive a little deeper into the chemistry behind the material. Photopolymerization is achieved through a reaction with a certain chemical group called thiols. By adding an oxidizer to the equation, thiols transform into another group called disulfides. It is the disulfide group that is able to reform when broken, leading to the self-healing ability. Finding the right ratio between these two groups was the key to unlocking the materials' unique properties. When we gradually increase the oxidant, the self-healing behavior becomes stronger, but the photopolymerization behavior becomes weaker. In just 5 seconds, they can print a 17.5-millimeter square, completing whole objects in around 20 minutes that can repair themselves in just a few hours. After being cut in half, in just two hours at 60 degrees Celsius (four for the electronics due to the carbon used to transmit electricity) they healed completely, retaining their strength and function. The repair time can be decreased just by raising the temperature. We actually show that under different temperatures -- from 40 degrees Celsius to 60 degrees Celsius -- the material can heal to almost 100 percent.

3-D Printed Body Parts

3D Bioprinting is the process of creating cell patterns in a confined space using 3D printing technologies, where cell function and viability are preserved within the printed construct. Generally, 3D bioprinting utilizes the layer-by-layer method to deposit materials known as Bioinks create tissue-like structures that are later used in medical and tissue engineering field. Bioprinting covers a broad range of materials. Currently, bioprinting can be used to print tissues and organs to help research drugs and pills. In addition, 3D bioprinting has begun to incorporate the printing of scaffolds. These scaffolds can be used to regenerate joints and ligaments. The first patent related to this technology was filed in the United States in 2003 and granted in 2006. 3D Bioprinting is the manufacturing of tissue or organ models by printing hydrogel seeded with live cells. Compared to non-biological printing, 3D bioprinting is more complex due to the choice of materials, cell types, growth and differentiation factors, and technical challenge related to the sensitivity of living cells and the complexities of functional tissues/organs.

3D Printing of Living Cells using a new technique they call ‘in-air microfluidics’. Microfluidics is all about manipulating tiny drops of fluid with sizes between a micrometer and a millimeter.

3-D Printed Body Parts. 3-D printed microfibers could provide structure for artificially grown body parts. Stem-cell-loaded hydrogels reinforced with fibers like the rebar in cement can grow living cells in defined patterns and eventually the fibers will dissolve and go away. If we could multiplex electrospinning with a collagen gel and bioprinting, we could build large and complex tissue interfaces, such as bone to cartilage. Low-cost and efficient method to fabricate high-resolution and repeatable 3-D polymer fiber patterns on nonconductive materials for tissue engineering with available hobbyist-grade 3-D printers. The method they use is a combination of 3-D printing and electrospinning, a method that uses electric charge to spin nanometer threads from either a polymer melt or solution. printer can deposit a precise pattern of fibers in three dimensions to form a scaffold in a hydrogel on which cells can grow. Once the tissue has grown sufficiently, the scaffolding can be dissolved, leaving only a structured tissue appropriate for use. If two different tissues -- muscle and tendon -- are needed, the 3-D printer can alter the pattern of threads in such a way that the transition could be seamless with the appropriate cells, resulting in a naturally formed, two-part tissue replacement.

Organ Bioprinting gets a breath of fresh air. Bioengineers have cleared a major hurdle on the path to 3D printing replacement organs. It's a breakthrough technique for bioprinting tissues with exquisitely entangled vascular networks that mimic the body's natural passageways for blood, air, lymph and other vital fluids.

Bio-Ink are substances made of living cells that can be used for 3D printing of complex tissue models. Bioinks are materials that mimic an extracellular matrix environment to support the adhesion, proliferation, and differentiation of living cells. Bioinks distinguish themselves from traditional biomaterials such as hydrogels, polymer networks, and foam scaffolds due to their ability to be deposited as filaments during an additive manufacturing process. Additionally, unlike traditional additive manufacturing materials such as thermoplastic polymers, ceramics, and metals which require the use of harsh solvents, cross-linking modalities and high temperatures to be printed, bioinks are processed under much milder conditions. These mild conditions are necessary to preserve compatibility with living cells, and prevent degradation of bioactive molecules and macroproteins. These bioinks are often adopted from existing hydrogel biomaterials and derived from natural polymers such as gelatins, alginates, fibrin, chitosan, and hyaluronic acids that are sensitive to their processing conditions. Unlike the thermoplastics that are often utilized in traditional 3D printing, the chain entanglements and ionic interactions within the hydrogel-like bioink rather than temperature dominate shape fidelity. The natural derivation of many bioinks often results in a high water content and sensitivity to harsh processing conditions. Therefore, bioink filaments are often deposited at or below human body temperature and under mild conditions to preserve bioink printability. Additional considerations must be taken into account when printing bioinks blended with a cell suspension due to the need to preserve cell viability. Differences from traditional 3D printing materials. Printed at a much lower temperature (37 °C or below). Mild cross-linking conditions. Natural derivation. Bioactive. Cell manipulatable.

Engineered Tissue Folding by Mechanical Compaction of the Mesenchyme. Many tissues fold into complex shapes during development. Controlling this process in vitro would represent an important advance for tissue engineering. We use embryonic tissue explants, finite element modeling, and 3D cell-patterning techniques to show that mechanical compaction of the extracellular matrix during mesenchymal condensation is sufficient to drive tissue folding along programmed trajectories. The process requires cell contractility, generates strains at tissue interfaces, and causes patterns of collagen alignment around and between condensates. Aligned collagen fibers support elevated tensions that promote the folding of interfaces along paths that can be predicted by modeling. We demonstrate the robustness and versatility of this strategy for sculpting tissue interfaces by directing the morphogenesis of a variety of folded tissue forms from patterns of mesenchymal condensates. These studies provide insight into the active mechanical properties of the embryonic mesenchyme and establish engineering strategies for more robustly directing tissue morphogenesis ex vivo.

Electrospinning is a fiber production method which uses electric force to draw charged threads of polymer solutions or polymer melts up to fiber diameters in the order of some hundred nanometers. Electrospinning shares characteristics of both electrospraying and conventional solution dry spinning of fibers. The process does not require the use of coagulation chemistry or high temperatures to produce solid threads from solution. This makes the process particularly suited to the production of fibers using large and complex molecules. Electrospinning from molten precursors is also practiced; this method ensures that no solvent can be carried over into the final product.

3-DIY: Printing your own Bioprinter. Researchers have developed a low-cost 3-D bioprinter by modifying a standard desktop 3-D printer, and they have released the breakthrough designs as open source so that anyone can build their own system.

Researchers develop 3D printed objects that can track and store how they are used. Engineers have developed 3D printed devices that can track and store their own use -- without using batteries or electronics. Instead, this system uses a method called backscatter, through which a device can share information by reflecting signals that have been transmitted to it with an antenna.

Backscatter is the reflection of waves, particles, or signals back to the direction from which they came. It is a diffuse reflection due to scattering, as opposed to specular reflection as from a mirror. Backscattering has important applications in astronomy, photography, and medical ultrasonography. The opposite effect is forward scatter, e.g. when a translucent material like a cloud diffuses sunlight, giving soft light.

Humans have been making their own stuff for thousands of years, so the makers movement is nothing new. The only thing that's new is the technology and our time in history. Starting in the 20th century, people got use to everything being made for them. And education got dumbed down to create factory workers. But then American corporations exploited cheap labor over seas that drastically reduced the number of jobs that were available. But the worst part was that education is still dumbed down, and millions of jobs are still being shipped to other countries to exploit a low paying labor force. Now machines and automation are increasing, and still education is being dumbed down. Technology has made people realize that they can make their own stuff. But the question is, should people be making their own stuff? Do they need to? And what are the options and choices that might be more productive, efficient and effective and less wasteful? But people are still undereducated. So it's almost impossible for anyone to accurately calculate the actual cost of their actions. 99 percent of people still have no idea of all the cause and effects that happen whenever they do something. Even when people do nothing, they still have no idea of the cause and effects of doing nothing. But we are making some progress. Technology is being democratized, but the most important thing is that knowledge and information also needs to be democratized. That's because only highly educated people can fully utilize technology without waste or abuse, as we can clearly see today. We need to improve education by 1,000 percent so that people fully understand themselves and the world around them. We want people to be independent and be able to survive on their own, but the most important thing is, people need to know how to work together to maximize our efforts, without wasting time, energy and resources. So mass production can still work really well if done right. It's great to make your own stuff and be independent, but everyone knows that we live on a planet with billions of other humans. So we need to understand this fact as well. Being highly educated and skilled would have to include being able to work together and fully utilize our strength in numbers. When everyone becomes an expert and a professional and becomes highly educated, then we will have have a much better world. Now put that in your 3D printer, and let's start going. Live, Learn ,Love and Progress, and then after that, maybe print something useful and see what happens, you never know, or do you?
