Inventors and product developers rarely need just one file — they need the full set. Our prototype design service bundle pairs a CAD package with a 2D technical drawing: a print-validated STL or 3MF, a manufacturing-ready STEP, the native SolidWorks file on Complex Part and Assembly, and the drawing, quoted together in a single order. One brief, one quote, one delivery.
What the Bundle Delivers
Every bundle is a CAD package plus the 2D drawing add-on: STEP AP214 for CNC machining and injection molding vendors, a print-ready STL or 3MF for your target print process, the native SolidWorks SLDPRT (and SLDASM for assemblies) on Complex Part and Assembly, and a 2D technical drawing with GD&T callouts as PDF and DWG. Other add-ons, such as a product render for Amazon or Kickstarter, are priced in the same quote. Every project is covered by an NDA on request; your files are never shown without your permission.
Print Validation Before Every Delivery
Our 3D CAD design for 3D printing workflow includes manifold check, wall thickness validation (minimum 1.2mm for FDM, 0.5mm for SLA), overhanging feature analysis, and a build orientation recommendation before the STL leaves our studio. We also check part dimensions against your stated printer build volume and flag any features that will cause support removal difficulty. This process eliminates the most common causes of first-print failure. For assemblies we check interference fits, motion clearances and fastener compatibility digitally before we recommend a print. Our custom PCB enclosure portfolio item shows a complete bundle — modeled from scratch and delivered print-ready for an FDM printer in a single order.
For reference on additive manufacturing design principles, Proto Labs guide to design for additive manufacturing outlines the design rules our engineers apply to every print-bound STL.
Who This Bundle Is For
Our product design for inventors bundle consistently serves four client types. First-time inventors preparing for a prototype run who need files a local print shop or online service can accept without modification. Amazon FBA sellers validating packaging inserts or accessories before requesting manufacturing quotes. Kickstarter creators who need both render images and production files before their campaign launches. Engineers who have a concept but lack CAD skills to execute it, and need a trusted stl file design service to build and validate the geometry.
Delivery and Revision Policy
Assemblies with five or more components are quoted after a scope review before work begins. Revision rounds follow the package you choose (1, 2 or 3 rounds, with extra rounds available as an add-on) — enough to refine geometry based on real-world print feedback. For 3D printing design service projects we include a brief print settings note with delivery — recommended layer height, infill percentage, and support strategy tailored to your specific part geometry and target printer.
File Compatibility Across Your Supply Chain
A common problem with prototype files is that they work for one vendor but not another. The STL your local FDM printer accepts may not be the format your SLS bureau requires. The STEP your CNC shop uses may not be the same AP version your injection molder expects. Our prototype design service bundle delivers files tested against the most common vendor requirements — binary STL for consumer FDM printers, mesh-optimized STL for SLS and SLA bureaus, STEP AP214 for CNC machining, and STEP AP203 on request for older CAM systems. We also verify that all export units match your specified measurement system so scaling errors are caught before the files leave our studio, not after your first prototype arrives at the wrong size. This cross-vendor compatibility check is included with every cad design for 3d printing bundle at no additional cost.
