3D printing service for replacement and spare parts — no tooling, no minimum order.
When original tooling no longer exists, the OEM has discontinued the part, or lead times from legacy suppliers are unacceptable, our 3D printing service produces replacement parts on demand. Upload a CAD file or send us the original part for scan-to-CAD conversion — we produce exact replacements in production-grade materials with no tooling investment and no minimum order.
Challenges we solve
What replacement & spare parts teams need from a 3D printing service
Original tooling no longer exists
Legacy products, discontinued equipment, and vintage systems often have no active tooling. Traditional manufacturing requires rebuilding the tool from scratch — weeks of lead time and thousands of dollars. 3D printing requires only a CAD file. If no CAD file exists, our scan-to-CAD service reverse-engineers the geometry from a physical sample.
Low quantity does not justify traditional manufacturing
You need 5 replacement brackets, not 5,000. CNC shops have minimums and setup charges that make single-digit quantities uneconomical. Our 3D printing service produces 1–50 parts at the same per-part economics — no setup fees, no MOQs.
Production downtime from broken parts
When a critical fixture, bracket, or cover breaks on the production floor, every hour of downtime costs money. We ship replacement parts in 2–5 business days. For NYC-area facilities, same-day pickup or next-day delivery gets parts to your floor faster than any machine shop.
Managing spare parts inventory
Warehousing spare parts for every product variant, every equipment model, and every legacy system is expensive and wasteful. Digital inventory — CAD files stored securely, produced on demand — eliminates warehouse costs, obsolescence risk, and the overhead of tracking physical stock.

Best technologies for replacement & spare parts
Materials
Materials for replacement & spare parts
For structural replacement parts — brackets, clips, mounts — MJF Nylon PA12 delivers production-grade strength (1.8 GPa) with heat resistance to 175°C. PETG on FDM handles larger parts with chemical resistance. For parts requiring the highest stiffness and heat resistance, PC CF provides 8.0 GPa at 140°C HDT. For visual or cosmetic replacement parts, SLA Standard Resin delivers the smoothest surface finish (2 Ra μm).
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.
PC CF
FDM · Shore D 83
Polycarbonate carbon fiber. High stiffness and heat resistance for demanding structural applications.
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
Submit part
Upload your CAD file (STEP, STL, OBJ, 3MF). No CAD file? Send us the physical part or detailed measurements and we will reverse-engineer the geometry via scan-to-CAD.
Material match
We recommend the material that best matches the original part properties — stiffness, heat resistance, chemical exposure, and surface finish.
Production
Parts produced on FDM, SLA, or MJF with optimized orientation for mechanical performance. Same-day build start for files approved by 3:30 PM ET.
QA
Dimensional verification against your spec or the original part geometry. Visual inspection for surface quality.
Ship
Tracked shipping in 2–5 business days. Rush options for production emergencies.
FAQ
Frequently asked questions
Can you reproduce a part if I do not have a CAD file?
Yes. Send us the physical part and we will reverse-engineer the geometry using 3D scanning and CAD reconstruction. Typical scan-to-CAD turnaround is 3–5 business days, after which we can produce the replacement part.
Will the 3D printed replacement match the original material?
We match material properties as closely as possible. MJF Nylon PA12 approximates injection-molded nylon. PETG approximates ABS in many applications. PC CF provides stiffness comparable to aluminum for non-structural brackets. Exact material matching depends on the original material and application requirements.
How many replacement parts can I order?
One part or thousands. No minimum order quantity. If you need a single replacement bracket urgently, we produce and ship it. If you need 500 spare parts for inventory, same process at better per-part pricing.
Can you store my CAD file for future reorders?
Yes. Once we have produced your part, the file is available for reorder. Contact us when you need more and we produce from the same geometry with the same process parameters.
What about parts that need to be food-safe or chemically resistant?
PETG offers chemical resistance and food-safe options. For specific chemical exposure or regulatory requirements, discuss your application with our engineering team and we will recommend the right material.
