What is the 3D printing process for this material?
Rubber-65A is printed utilizing 3D Systems' Figure 4 DLP (digital light processing) 3D printing technology. The Figure 4 is a high-speed 3D printer that offers the quality and performance of injection-molded parts with smooth surface finish and exceptional sidewall quality, without the time or cost of tooling.
Will there be support scarring on this part?
The figure 4 material utilizes small supports similar to stereolithography (SLA). When removing the support structure duing post processing, small nubs will remain on the part. it is important to identify the class A surface of the part before printing to ensure that the small support nubs do not touch the crititcal surface of the part.
How long will it take before I receive my part in this material?
Production times vary depending on machine availability, but generally Rubber-65A parts are printed and shipped within 2-3 business days.
What are some of the specific design considerations when designing parts for this material?
The design considerations recommended for Rubber-65A are similar to those recommended for any photopolymer 3D printing technology. You will want to give thought to the kinds of design considerations and fundamental ranges of capability that apply for any manufacturing device, such as minimal wall thicknesses and things of that nature, which tend to vary from geometry to geometry and part to part. Often the best way to determine the functional range for a specific application is to print it and test it. Iterate out all the opportunities for manufacturing efficiencies before you scale up to high volume production.
