Custom injection molder Kaso Plastics Inc. has brought 3D printing for rapid prototyping in house. The Vancouver, Wash., firm invested about $100,000 in the program, including a Fortus 250 3D printer production system from Stratasys Inc. of Eden Prairie, Minn. The 3D printing system allows rapid production of ABS prototypes. It will help Kaso staff identify any possible design flaws early in the production process, saving time and money for the customer. Kaso claims it will be able to make ABS prototype parts nearly as strong as an injection molded part, in some cases with 80 percent of the strength of conventional injected parts. Eventually the privately held firm could use the 3D system as a cost-effective way of doing short runs of finished product.
