How it Works
In the rapid prototyping world there are many processes and options available depending on a user’s unique application. At the core of rapid prototyping lies the ability to produce parts and models that mirror either the end-use specification or multiple prototypes that act as part of a series in a new product development endeavor. The ability to prototype quickly and conveniently directly impacts any design or development process, resulting in both cost and time savings.
Prototyping Processes
PolyJet Technology works by jetting state of the art photopolymer materials in ultra-thin layers (16µ) onto a build tray layer by layer until the part is completed. The Technology was first created by Objet Geometries. This Polyjet Matrix Technology provided businesses and consumers alike with the tools to produce multi-material parts, however complex, in a timely manner. This technology is continuously improving, allowing for smaller machines, more accurate builds, and cost effective solutions.
Stereolithography (SL or SLA) is an additive manufacturing technology for producing models, prototypes, patterns, and in some cases, production parts. This rapid prototyping process involves layering liquid photopolymer resin cured by a UV laser solidifying the final state.
Selective laser sintering (SLS) is an additive manufacturing technique that uses a high power laser (for example, a carbon dioxide laser) to fuse small particles of plastic, metal (direct metal laser sintering), ceramic, or glass powders into a mass that has a desired 3-dimensional shape.
Fused Deposition Modeling (FDM) is an additive manufacturing technique commonly used in the rapid prototyping industry. It has a variety of applications but is most often used for modeling, prototyping and production applications. Fused deposition modeling is an additive process that layers the material to produce the finished prototype. A plastic or metal coil is unwound through a heated nozzle, melting the material in the desired shape. The most common materials used in this process are ABS and PLA, but there are hundreds of choices available. From wood composites, carbon fibre or even medical grade options.
