Sometimes referred to as additive manufacturing, 3D printing involves layering materials, such as plastics, composites, or biomaterials, to create objects that vary in shape, size, stiffness, and color. Three-dimensional (3D) printing is an additive manufacturing process that creates a physical object from a digital design. The process works by placing thin layers of material in the form of liquid or powdered plastic, metal, or cement, and then fusing the layers together. DLP or digital light processing refers to a printing method that uses light-sensitive and photosensitive polymers.
And so, in the early nineties there was an increasing number of competing companies in the PR market, but only three of the originals remain today 3D Systems, EOS and Stratasys. Hull co-founded 3D Systems Corporation, one of the largest and most prolific organizations operating in the 3D printing industry today. Jewelry professionals use CAD and 3D printing to quickly prototype designs, adapt to customers, and produce large batches of ready-to-cast parts. Multi-material 3D printing solves this problem by allowing objects of complex and heterogeneous arrangements of materials to be manufactured with a single printer.
Propionic acid production by Propionibacterium acidipropionici immobilized on 3D printed nylon beads was chosen as a model study. Rapid prototyping with 3D printing enables engineers and product designers to turn ideas into realistic proof-of-concept, turn these concepts into high-fidelity prototypes that look and function as final products, and guide products through a series of validation steps to production in mass. Living tissue is being researched at several leading institutions in order to develop applications that include printing human organs for transplants, as well as external tissues to replace parts of the body. These resins are formulated for 3D printing of anatomical models, components of medical devices and devices, and surgical planning and implant sizing tools.
SLA resin 3D printers have become very popular for their ability to produce high-precision, isotropic and hermetic prototypes and parts in a range of advanced materials with fine characteristics and a smooth surface finish. Larger 3D printing companies, such as 3D Systems and Makerbot, as a subsidiary of Stratasys, are moving in this direction, as they try to make the 3D printing process and auxiliary components (software, digital content, etc.) more accessible and easier to use. Nervous System launched the first line of 3D printed ceramic jewelry, consisting of intricate designs that would be impossible to manufacture with any other ceramic technique. FDM industrial 3D printers use soluble media to mitigate some of these problems and offer a wider range of engineered thermoplastics, but they also come at a high price.
Engineered materials are ideal for 3D printing robust and accurate prototypes and conceptual models to quickly iterate designs, evaluate form and fit, and optimize manufacturing processes. Today, EOS systems are recognized around the world for their quality results for industrial prototyping and 3D printing production applications.
