Powdered thermoplastic (typically nylon) is precisely fused by a high-powered laser. Parts are cleaned of excess powder and ready for use or higher level finishing. **Also known as Selective Laser Sintering (SLS)
Laser sintering can be used to create tough, geometrically complex components for manufacturing. Following vapor smoothing, these production parts are water-tight, air-tight, heat resistant, strong, and easy to reproduce. Nylon also offers the possibility of producing living hinges and flexible end-use parts and can be easily dyed in a variety of colors.
Multi Jet Fusion
Powdered thermoplastic is precisely fused by a liquid agent and infrared energy. Parts are cleaned of excess powder and ready for use or higher level finishing.
Multi Jet Fusion offers more possibilities for complex, low-cost parts. Ideal applications are connectors, hinges, brackets, thin-wall ductwork, and non-cosmetic housings. It is great for industries that need to produce high-volume limited run spare parts.
Ultraviolet-sensitive liquid resins are instantly cured when activated by a high-performance UV laser. Parts are post-processed with additional UV and thermal treatments (when necessary).
Stereolithography is an extremely fast and highly accurate process used most commonly for form and fit prototypes, master patterns, and large concept models. This combined speed and design freedom in stereolithography enables rapid iteration for new product development.
Digital Light Processing
Ultraviolet-sensitive liquid resins are cured by a UV projector layer by layer. After processing, the part is cleaned, supports removed and then UV and/or thermal treated (if necessary).
Digital light processing is a fantastic option for designers and engineers that require high detail and finish in a variety of production-grade materials with different durometers and characteristics, from silicone to high-temp cyanate ester. Good for small end-use parts, light metal part substitutions, functional, high-detail prototypes, jigs, and fixtures.
Fused Filament Fabrication
The thermoplastic filament is melted through a heated nozzle and selectively extruded, building layer upon layer. After building, supports are removed.
An industry standard, fused filament fabrication is a process that provides engineers and designers numerous material options with our open machine platform. Durable, rigid, single-color parts with moderate detail are good for check fixtures, specialized tools functional prototypes, and end-use parts.
An ultraviolet-sensitive gel is deposited by a print head then immediately cured by a UV lamp.
Material jetting is a solution for designers who want excellent visual models with end-product feel. This technology also allows for multiple materials to be incorporated into one print. It is good for complex, flexible models.
A liquid plastic is poured into a "soft" silicone mold and then cured in a vacuum chamber.
Cast urethane is great for quickly produced low-cost plastic parts. When looking for a great option for prototyping or low-volume production of flexible, rigid, colored, and clear plastic parts cast urethane should absolutely make the shortlist.
3D laser scanning uses a line of laser light to capture the shape of physical objects.
This technology is a non-contact and non-destructive way to capture the object’s exact size and shape and creates a 3D digital copy of the object on a computer.
Finishing and Post Processing
There are many options for finishing and post processing your professional models, prototypes, and end-use parts.
Finishing and post-processing options at Midwest Prototyping include full-colored, painted, tinted, dyed, clear finishes, electroplated (copper, nickel, or chrome), ink transfers, sandblasted finishes, laser engraved logos, and vinyl graphics.
We carry a wide range of materials that can be used for many applications.
Our Materials Pro database allows materials to be searched by both technology and key characteristics. If you’re unsure of a material or technology for your project it is a great tool to narrow down results. Please contact a Solutions Manager to make sure the material and technology is a perfect fit.
