Selecting a Rapid-Service Bureau
better pricing and better solutions. Considerations in selecting an RP service bureau include: processes, timing, expertise, and customer service. Find out whether the service bureau offers the major RP technologies. They are stereolithography (SLA), selective laser sintering (SLS), and fused-deposition

Quick Start for Rapid Prototyping
Stereolithography, photochemical machining, laser sintering, and laminated-object manufacturing use 3D CAD data to produce models in hours. Most of these processes make parts from plastic. Models can be built from layers of liquid plastic, fused from plastic powders, or cut from partially cured

Case Study: Dimension 3D Printer Powers Freedom of Design at Black & Decker
to constantly launch new ranges means that the company is always looking for faster ways to get products developed and into stores. Previously Black & Decker used a combination of in-house CNC milling for tooling while outsourcing stereolithography (SLA) and laser sintering (SLS) parts when designing new

Process Creates Ceramics That Won't Shrink Or Change Shape
implants, cellular phones, gas or temperature sensors, and even automobile engines. Manufacturers of expensive, complex-shaped ceramic components must fire freshly-molded parts at high temperatures in order to obtain a ceramic body that is free of pores. This pore-filling process, called sintering

Fused Depostion Modeling: A Technology Evaluation
author, published in Time Compression Technologies; August, 2002 filled this knowledge gap, from a user perspective, for three technologies: Stereolithography (SLA), Selective Laser Sintering (SLS) and PolyJet. To add to this body of information, another leading technology, fused deposition modeling

Rapid-prototyping resin good enough for wind-tunnel tests
it perform better than existing trainers. The creation of an accurate, scaled prototype for wind-tunnel testing was essential to the development process. The inherent complexity of the M-346 prototype made Provel decide to produce the model using SL rather than a powder-sintering technique. ProtoToolT 20L

Refractory Hard Metals
are made by conventional powder-metallurgy compacting and sintering methods. Many metal carbides such as SiC and BC are not RHMs but are true ceramics. The fine distinction is in particle bonding: RHMs are always bonded together by a metal matrix, whereas ceramic particles are self-bonded. Some

Flouroplastics
processed by conventional extrusion and molding techniques. Instead, molding resins are processed by press-and-sinter methods similar to those of powder metallurgy or by lubricated extrusion and sintering. All other fluoroplastics are melt processible by techniques commonly used with other
