"Trustworthy. The price of my 3d print was very competitive. Arrived about 10 days after submitting the 3d file (from China). The prints were high detail resin, and I'm very satisfied with the quality. Will definitely have them print more in the near future. Sent via UPS with tracking."

"Unionfab is great! I use Unionfab's 3D printing services to create metal sculptures that aren't otherwise possible. They always give feedback to make sure the design is optimized for printing, and their website keeps a great timeline of my projects from start to finish. They're very communicative, prices are reasonable even for metal printing services."
