3D Printing


3D Printing is also known as additive manufacturing (AM), refers to various processes used to synthesize a three-dimensional object. In 3D 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 Modeling is the process of developing a mathematical representation of any three-dimensional surface of an object (either inanimate or living) via specialized software.

Stereolithography 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.

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.

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.

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.

New printing technique uses cells and molecules to recreate biological structures.
 
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.

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?
