protoCAD Corp is a small engineering services company based in La Plata, Maryland, USA. Founded in 1993, its website states that it offers more than 30 years of personalized design engineering, 3D printing, and polyurethane casting services. It is not online design software, but rather an engineering and rapid manufacturing service provider for product development. Its customers include individual inventors, engineers, Fortune 500 companies, and U.S. government agencies.
Its core services include SLA/SLS 3D printing, which can produce parts directly from 3D CAD data within hours. Its polyurethane vacuum casting can produce rigid or flexible, near-production-quality parts, and the site also mentions silicone casting capabilities. On the engineering side, it uses Pro/ENGINEER Creo for CAD modeling, covering concept definition, complete 3D models, complex surfacing, manufacturing-ready data, renderings, detailed engineering drawings, ANSI Y14.5M GD&T, tolerance analysis, and patent drawings. In-house equipment includes 3D printing, large and small vacuum casting equipment, rotational casting, CNC mills, a model shop, painting, and woodworking equipment. Its external partner network covers machining, sheet metal, injection molding, RIM, and thermoforming.
The website only provides Quick Quote, Request A Quote, and phone contact options. It does not publicly list material prices, processing rates, minimum order quantities, or standard lead times. The text mentions that 3D printing can be completed within hours and vacuum-cast parts can be delivered within days, but specifics still need to be confirmed on a project-by-project basis.
The advantages are its solid engineering background and ability to provide continuous services from concept, CAD, and prototyping through pilot production. It also has government project experience and ITAR registration information, making it suitable for complex mechanical parts and projects that require human engineering judgment. The drawbacks are limited online transparency, with no instant quoting, file specifications, material library, quality certifications, or cross-border service information. It is not very friendly for users who simply want to upload a model, compare prices quickly, and place an order by themselves.
It is better suited to U.S.-based hardware startups, mechanical engineering teams, manufacturing companies’ R&D departments, customers needing small-batch polyurethane parts or engineering fixtures, and projects with government requirements or high-specification drawing standards.
The website content does not provide information about access from China, Chinese-language service, international shipping, or payment methods, so its accessibility from China is unknown. Chinese customers who wish to work with the company should pay close attention to export controls, ITAR restrictions, logistics, and payment arrangements.
