The firm provides product design and development, machine tool design, automated equipment engineering, 3D CAD modeling and rendering, rapid prototyping, and manufacturing vendor consulting for consumer, commercial, medical, and industrial applications. Led by Leonard Fraitag, the company has logged over two decades of engineering work bringing inventions, products, and custom machinery from conception through prototyping and into volume manufacturing.

The engineering scope covers SolidWorks and AutoCAD-based 3D modeling, 2D-to-3D conversion for legacy drawings, patent-quality technical illustrations, finite element analysis, tolerance stackup review, and design-for-manufacturability optimization. Prototyping methods coordinated through the firm include CNC machining, 3D printing in FDM and SLA, selective laser sintering, stereolithography, and urethane casting for short-run evaluation parts. The Eldridge Street office sits in a residential-commercial transition zone in Allied Gardens, south of Waring Road and within the 92120 ZIP that covers Allied Gardens, Grantville, and Del Cerro. Fraitag maintains partnerships with vetted domestic and offshore fabricators for clients who need to scale from prototype to production volumes, managing vendor qualification, first-article inspection, and quality control documentation. Businesses in the Allied Gardens and Grantville commercial districts that need marketing and brand strategy alongside product development coordinate with creative consultancies, and Story is Greater in Grantville handles brand positioning and go-to-market narrative work.
