Parts On Demand - PRO BLK-10
Material Overview
PRO BLK-10 is a production-grade additive manufacturing material with game-changing thermoplastic-like mechanical properties and long-term environmental stability. It is 3D printed using precision DLP (Digital Light Printing) 3D printing technology. This high precision 3D resin produces parts with a smooth surface finish and great sidewall quality.
Common Applications
Direct production of small black plastic parts; examples include: motor housings, connectors, snap-fits, automotive interior and other general-use parts
Indoor Stability
Tested per ASTM D4329 standard method.
Outdoor Stability
Tested per ASTM G154 standard method.

What is the 3D printing process for this material?
PRO-BLK 10 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 PRO-BLK 10 parts are printed and shipped within 1-2 business days.
What is the part accuracy and tolerances that this material can hold?
Accuracy is dependent on the geometry in question; not just the size of the part, but also the shape and cross-sections. As such, accuracy capability is best evaluated in the context of a specific part example. For the small plastic part in the presentation, we were able to get around 35 microns on average, with a range of +/- 150 microns. In a dental application for a 60,000 micron arch, we were able to keep 100% of surfaces within +/- 100 microns
What are some of the specific design considerations when designing parts for this material?
The design considerations recommended for Pro-BLK 10 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.
