3D Printing Design Services in Charlotte NC
No CAD file? No problem. From napkin sketches to production-ready models — we handle CAD modeling, DFM review, and reverse engineering for businesses across Charlotte and Lake Norman.
What We Offer
From Idea to Print-Ready File
CAD Modeling from Scratch
Send us a sketch, photo, or description — we create production-ready 3D models optimized for 3D printing with precise dimensions and tolerances.
Design for Manufacturing (DFM)
Optimize existing designs for 3D printing — better strength, less material, fewer supports. We catch issues before they become expensive print failures.
Reverse Engineering
Broken or discontinued part? We measure and recreate digital models from physical samples — no original CAD file needed.
How It Works
From Description to Finished Part in 4 Steps
Describe Your Part
Share sketches, photos, dimensions, or the physical part itself. We work from whatever you have.
Design & Iterate
We create the 3D model and refine it with your feedback — typically 2-3 revision rounds until it is exactly right.
DFM Review
We optimize the design for printability, material efficiency, and structural integrity before production.
Print-Ready Files
You receive production-ready STL/STEP files and printed parts — ready for use, testing, or production.
Materials & Specs
Material Recommendations Included
We Recommend the Right Material
Material selection depends on your application — strength requirements, environment, aesthetics, and budget all factor in. During DFM review, we recommend the best material for your specific use case.
- PLA for visual models and concept presentations
- PETG for functional parts requiring chemical resistance
- ABS/ASA for heat resistance and outdoor durability
- Nylon for high-strength mechanical components
- TPU for flexible gaskets, seals, and grips
File Formats We Deliver
Every design project includes production-ready files in the formats you need. We also provide source files so you can make future modifications.
- STL — Standard mesh format for 3D printing
- STEP — Editable CAD format for future modifications
- 3MF — Modern format with material and color data
- OBJ — Compatible with most 3D software
Case Study
Charlotte HVAC Company Gets a Part That Lasts 3x Longer
Challenge
A Charlotte HVAC company had a custom mounting bracket that broke regularly under vibration and thermal cycling. No CAD file existed — only a worn-out original part that was failing every few months.
Solution
CLT 3D Printing reverse-engineered the bracket from the broken original, redesigned stress points for improved strength, and printed the new version in Nylon for maximum durability.
Result
The redesigned Nylon bracket lasted 3x longer than the original. The HVAC company now reorders replacement brackets on-demand — no inventory needed.
