3D Printing Services Houston
CAD Design Services Houston, TX
Great designs start with great CAD files. Spline Arc provides professional CAD design services in Houston for engineers, product developers, and businesses that need to go from concept to physical part without the overhead of a full in-house design team. Whether you have a hand sketch, a rough prototype, or a broken part that needs reverse engineering, we produce print-ready files optimized for FDM, resin, or CNC production.

3D Modeling from Concept to Production
We take your concept—sketches, reference photos, written descriptions, or verbal briefs—and model it in 3D. Using Rhinoceros 3D, Fusion 360, and SolidWorks, we produce accurate, manufacturable models that account for material behavior, print orientation, support requirements, and assembly tolerances.
File Repair and Optimization
Not all STL or STEP files are print-ready. Mesh errors, non-manifold edges, thin walls, and incorrect tolerances cause print failures and wasted material. We analyze, repair, and optimize your files so they print correctly the first time. This includes:
- Mesh repair and watertight sealing
- Wall thickness verification and reinforcement
- Support structure optimization
- Orientation analysis for strength and surface quality
- Tolerance checking for assembly fit
- File conversion between formats (STL, STEP, OBJ, 3MF)
Reverse Engineering
When you have a physical part but no digital file, we reverse engineer it. Using our mobile 3D scanning capability, we capture the geometry of your part, clean the scan data, and produce a solid model ready for printing or CNC machining. This is ideal for discontinued parts, legacy equipment, and custom modifications.
Design for Manufacturing (DFM) Consulting
Before you print, we review your design for manufacturability. Our DFM analysis identifies potential issues—thin walls, unsupported overhangs, insufficient clearances, and weak joint designs—before they become expensive problems. We recommend material substitutions, geometry changes, and assembly modifications that improve print success and part performance.
CAD-to-Print Workflow
- Concept Review: We discuss your requirements, material constraints, and functional goals.
- Modeling: We produce the 3D model, with progress reviews at key milestones.
- Design Validation: We check for printability, strength, and assembly fit.
- File Delivery: You receive the native CAD file, STL, STEP, and print-ready documentation.
- Prototype Production: We print the first article for validation before production.
