Whether you have a rough sketch on a napkin, an existing physical part that needs to be digitized, or a partially complete design that needs engineering refinement, our designers work in the same software your team uses — SolidWorks, Fusion 360, Rhino, and beyond.
Every model we deliver is print-ready and manufacturing-ready. We don't just create pretty 3D files — we build geometry that accounts for material behavior, wall thickness minimums, assembly tolerances, and post-processing shrinkage. This design-for-manufacturing (DFM) approach means your first print is much more likely to be your final prototype.
Located in Houston, Texas, we serve engineers, product developers, architects, prop fabricators, and entrepreneurs across the Gulf Coast and ship digitally worldwide. Our NDA-protected design workflow keeps your IP safe at every stage.
We work natively in the industry's leading CAD platforms and accept files in virtually every format. No conversion headaches — we start from wherever you are.

| IGES (.igs) | Neutral surface | Aerospace, legacy systems | Both |
| 3MF (.3mf) | Print-optimized mesh | Full-color & multi-material printing | Both |
| Blender (.blend) | Polygon mesh | Organic, artistic, props | Import |
Feature-based, history-driven 3D models in SolidWorks or Fusion 360. Every dimension is parametric — changes propagate through the entire design. Ideal for engineered parts with tight tolerances and revision cycles.
We digitize physical objects into accurate CAD geometry using calipers, digital measurement tools, and structured-light scanning references. Perfect for recreating legacy parts with no surviving drawings.
Complex curved surfaces, ergonomic forms, and organic shapes that parametric tools struggle with. Built in Rhino or Blender with controlled surface continuity for aesthetic products, props, and art.
We review your existing CAD files and flag issues before you spend money on prints. Wall thickness, draft angles, undercuts, support-unfriendly geometry, and tolerance stacks all get addressed upfront.
Broken meshes, non-manifold geometry, and incorrect normals are common in files sourced from internet repositories or scans. We repair and optimize STL and mesh files for clean, reliable prints.
Multi-part assemblies with moving components, snap fits, threaded inserts, hinges, and interlocking features. We model for fit, function, and assembly sequence to ensure parts go together the first time.
Startups and inventors use our CAD services to take ideas from sketch to first prototype in days. We model around your function requirements and iterate rapidly based on physical test results.
Architects and developers commission highly accurate scale models of buildings, interiors, and site plans. Our CAD team translates architectural drawings and BIM exports into print-ready geometry.
Film and TV productions, cosplay creators, and museums need accurate prop files. We model from reference images, existing props, or original creative briefs to create print-ready prop geometry.
OEM replacement parts, jigs, fixtures, and tooling inserts modeled to print-and-install specifications. Our engineers understand GD&T, material behavior, and functional load requirements.
Rings, pendants, and wearable art modeled with the tight tolerances required for casting masters and direct-print pieces. Rhino and Blender surface workflows ensure smooth, organic forms.
Anatomical models, surgical guides, and medical device prototypes. Our CAD team works from DICOM references, specification sheets, and engineering requirements to produce compliant geometry.
We follow a structured design workflow that keeps projects moving and keeps you informed at every milestone.
You send us sketches, reference images, physical samples, or a written brief. We review all materials and ask clarifying questions before starting — no guessing games.
Our designer builds the initial model and sends a render or screenshot for visual approval before finalizing geometry. This catches conceptual mismatches early.
Every model goes through our DFM checklist — wall thickness, overhangs, tolerances, and print orientation are all verified before file delivery.
You receive your native CAD file, STEP export, and print-ready STL. Renders and technical drawings are available as add-ons.
If you're printing with us, your file moves directly to our production queue. CAD design fees are credited toward print orders over a certain threshold.
Physical test reveals issues? We revise the model. Our parametric workflow means changes are fast — not a rebuild from scratch.
No. We can create the CAD file for you. Many clients come to us with only a sketch, a reference image, or a physical sample. Our design team produces print-ready files as a standalone service that can then feed directly into your print order.
Yes. We routinely execute mutual NDAs before design work begins, particularly for product development clients with novel IP. Contact us before sending files and we'll get the NDA in place first.
File repair and DFM optimization is one of our most common services. Send us your file, we'll diagnose the issues, and provide a fixed print-ready version. We'll always explain what was wrong so you can avoid the same issues in future designs.
We model multi-part assemblies with fit tolerances baked in from the start. Our standard approach is to print a first-article assembly test — checking fit, clearance, and function — before proceeding to any production quantity.
At minimum, a written description of the part's function, approximate dimensions, and any critical features. Sketches, reference images, or similar products help us model faster and more accurately. The more reference material you provide, the faster and cheaper the design work will be.
Send us your sketch, reference, or idea. Our CAD team will review your project and send a detailed quote within one business day.
