What We Do

Comprehensive File Conversion & Optimization

We go beyond simple format conversion — we prepare, clean, and optimize your files so every print comes out exactly right the first time.

CAD to STL Conversion

Convert files from SOLIDWORKS, CATIA, Fusion 360, AutoCAD, Rhino, Pro/E, STEP, IGES, and more into optimized, print-ready STL files with precise tolerances.

File Repair & Healing

Diagnose and fix non-manifold geometry, inverted normals, open shells, self-intersections, and other mesh errors that prevent successful 3D printing.

Mesh Optimization

Reduce polygon count for faster processing without sacrificing detail, or increase mesh density where dimensional accuracy is critical for your application.

Scale & Dimension Correction

Correct unit mismatches, re-scale models to exact dimensions, and ensure your design meets the required tolerances for its intended print technology.

Multi-Body & Assembly Prep

Split or merge multi-body assemblies, orient parts for optimal printing, and prepare complex assemblies for single-print or multi-component production runs.

Pre-Print Validation

Thorough analysis for wall thickness, overhang angles, and printability before production begins — catching issues early to save time and cost.

Our Process

From File to Print-Ready in 4 Simple Steps

A streamlined, expert-guided process that takes the complexity out of file preparation and gets your project moving fast.

STEP 1

Submit Your File

Upload your design file through our quote form in any supported format. Include notes on your end-use requirements, tolerances, and print technology preference.

STEP 2

Engineering Review

Our engineers analyze your file for errors, geometry issues, and printability concerns. We'll identify any problems and recommend the optimal conversion approach.

STEP 3

Convert & Optimize

We perform the conversion, repair any mesh errors, optimize geometry, and confirm scale and dimensions are accurate before handing off for production.

STEP 4

Ready to Print

Your optimized STL is validated and handed directly to our production team — or returned to you — ready for immediate, accurate 3D printing.

Why Work With Us

Expert Engineers, Not Just Software

File conversion isn't just a technical task — it requires deep understanding of 3D printing processes, material behavior, and design intent. Our experienced team at our Minneapolis and Denver facilities ensures every file is production-optimized, not just format-converted.

Technology-Aware Conversion

Files are optimized specifically for the target print technology — FDM, SLS, or SLA — accounting for unique tolerances and material properties.

Seamless Path to Production

When you print with us, your converted file goes directly into our production workflow — no re-uploads, no miscommunication, no delay.

17+ Years of File Experience

We've processed files from startups, entrepreneurs, and Fortune 100 engineering teams. Whatever your source, we know how to make it print right.

Fast Turnaround — Typically 24 Hours

Most file conversions are completed within one business day so your production timeline stays on track.
