3D printing for legacy part replacement — reverse-engineer and reproduce discontinued parts.
When a part is discontinued and the original tooling no longer exists, 3D printing is often the only viable path to reproduction. Our service combines reverse engineering — from 3D scans, physical samples, or original drawings — with production-grade 3D printing to reproduce legacy parts on demand.
Challenges we solve
What legacy part replacement teams need from a 3D printing service
Reproducing parts without CAD files
Original CAD files rarely survive product discontinuation. We reverse-engineer from 3D scans, physical samples, or original drawings — creating production-ready CAD files from whatever reference you have.
Matching original material performance
Legacy parts were often injection-molded or machined. We match the mechanical properties as closely as possible with production-grade 3D printing materials. For critical applications, we provide material data for your engineering review.
Producing one-off replacements economically
Traditional manufacturing has minimum quantities. 3D printing has no minimum — produce one part or one hundred with the same process and quality.
Creating a digital archive for future needs
Once a part is reverse-engineered and the CAD file exists, it can be reproduced indefinitely. We create a permanent digital record of your legacy parts.

Materials
Materials for legacy part replacement
Material selection matches the original part performance. Nylon PA12 for structural components. PETG for chemical-resistant parts. ABS for impact-resistant housings. Flexible resin for gaskets and seals. We evaluate the original material and recommend the closest 3D printing equivalent.
Nylon PA12
MJF · Shore D 73
Strong, lightweight, chemical resistant. The standard for functional end-use parts. Excellent fatigue resistance and consistent mechanical properties.
PETG
FDM · Shore D 74
Tough, chemical resistant, food-safe options. Good balance of strength and flexibility.
ABS
FGF · Rockwell R 110
Impact resistant, heat tolerant. The standard for extra-large format builds.
Standard Resin
SLA · Shore D 78
Smooth surface, fine detail. Good for visual prototypes and concept models.

How it works
Your project, step by step
Send reference
Send the physical part, 3D scan, drawing, or photo with dimensions. Whatever you have — we work with it.
Reverse engineer
Our design team creates production-ready CAD from your reference. You approve the digital model before printing.
Material match
We recommend the 3D printing material that best matches the original part performance.
Print & verify
Part produced and dimensionally verified against the original or the approved CAD model.
Deliver & archive
Part shipped. CAD file archived for future reproduction on demand.
FAQ
Frequently asked questions
What if I only have the broken original part?
We work with broken, worn, or partial parts. Our design team reconstructs the complete geometry from whatever reference is available.
How long does reverse engineering take?
Simple parts: 1–2 business days. Complex geometry: 3–5 business days. We provide a timeline estimate after reviewing your reference material.
Can reproduced parts handle the same loads?
We match material properties as closely as possible. For critical structural applications, we provide material data and recommend testing before putting the part into service.
