Hercules also makes resin dispersions in Hattiesburg, Miss.
Plynetics expands stereolithograpgy
SAN LEANDRO, CALIF. - Plynetics Corp., a supplier of rapid prototyping services, has more than doubled its stereolithography capacity with the addition of a new machine and enhancement of existing systems.

Prototype firm has Singapore bureau
HEBRON, KY.-Accelerated Technologies Inc. of Hebron is opening a new service bureau subsidiary in Singapore called Accelerated Technologies Singapore PTE Ltd.
ATI Singapore will offer computer-aided design services, reverse engineering and rapid prototyping technology using both Selective Laser Sintering and stereolithography, said President Mike Ellison.
The newest rapid prototyping technology, SLS, is a thermal process that uses a laser to sinter or fuse layers of powdered thermoplastic materials together to form solid three-dimensional objects. SLS can process a variety of prototyping materials including polycarbonate, investment casting wax, standard nylon, fine nylon and glass-filled nylon.
Powdered metal is used for the production of prototype injection molds.
Stereolithography, the first commercially available rapid prototyping technology, uses photopolymer resins cured using ultraviolet laser energy to produce solid, three-dimensional objects.
Ellison said ATI Singapore also plans to do some injection mold making and casting.
Although ATI has had a presence in Singapore since October, a service bureau there will improve the company's service, he said. According to Ellison, there are some 900 multinational companies manufacturing in Singapore.
ATI opened with five employees and will grow to 15 within a year, Ellison said. In addition to the facility in Hebron, ATI has a service bureau in Austin, Texas, and employs 30 companywide.
