Many of ProtoCAM’s additive manufacturing and rapid prototyping customers use the STL viewer from SolidView.
Although there are different levels of features available for various prices, SolidView/Lite is a good, free STL viewer. Use this to preview any STL files you send to ProtoCAM. (ProtoCAM can create them ourselves from other formats, too.)
Visit the Netfabb Basic website for the download link. A free user account is typically required. Note: Netfabb is not our product, although we have used and recommended it to clients needing an STL view, and part volume, section and measure tools. For assistance with the software, please visit their website or contact their support team.
If you need additional details or want to discuss other formats with ProtoCAM, give us a call at 610-261-9010 or write to firstname.lastname@example.org.
