Matt's Garage Printing is a manufacturing company based in Prairie Grove, Arkansas. They offer to print in gray Resin via an SLA technology. Our test model was printed to good quality: no defects were spotted on the surface, it came out very smooth and flawless, the surface elements and tiny "bridges" on the top of the part turned out very neat and accurate. All the dimensions are well preserved. The vendor provided us with the result within 24 hours.
