Antique Castings Replacements

Through 3D scanning and 3D printing, we offer model designing and casting duplications for hard to repair, hard to replace antique racing and road car components. We can take the broken physical part, reverse engineer it, model it, 3D print it, and send the model through our lost-wax casting process to create a replacement casting that attains as much detail as jewelry (for those irreplaceable casting numbers or logos for authentic replacements).
