Give us your existing blue print and we will manufacture your product to your specification. We will test your complete assembly and validate your product.  Outsourcing manufacturing to a build-to-print specialist allows you to focus on other business needs and doesn't consume your resources.   Projects move faster and in many cases it is a more cost effective way to build your parts & products.  InSource specializes in Build-To-Print manufacturing in the following areas:

  • Mechanical Assemblies
  • Electromechanical Assemblies
  • Electronic Assemblies
Markforged Mark Two 3D Printer


Using our Markforged 3D printer we can produce exact copies of your CAD file overnight, in a variety of high strength premium materials Onyx, Carbon Fiber, Kevlar and Fiber Glass. Once a part is made we build a mold, which enables us to make additional copies at a fraction of the cost.
