Applications
3D printed spare parts — on demand
OEM discontinued the part? Lead time from the supplier is 12 weeks? Send us a drawing, a scan or the broken original. We reproduce industrial plastic spare parts in days, not months — one unit or a hundred.

Quick answer
3DadditHub reproduces obsolete, discontinued and custom industrial spare parts using additive manufacturing. We work from a 2D drawing, a 3D file, a scan, or a physical sample of the broken part. Typical materials are ABS, ASA, PA12 (SLS/MJF), PC and ULTEM. Lead time is 3–7 working days. We do not supply safety-critical, load-bearing or regulated parts.
What we make
Typical spare parts we reproduce
Non-critical industrial plastic parts where OEM stock is gone or lead time is unacceptable.
- Obsolete machinery parts from discontinued equipment
- Plastic knobs, handles, grips and control levers
- Housings, covers, panels and protective enclosures
- Brackets, mounts and structural clips (non-load-bearing)
- Connectors, adaptors and cable-management components
- Custom jigs, fixtures and tooling replacements
- Legacy appliance parts (white goods, HVAC, industrial ovens)
- Automotive interior trim, clips and non-safety components
- Prototype tooling and end-of-line replacement inserts
How it works
From broken part to shipped replacement
Send what you have
Drawing, STEP file, scan, or a photo with a calliper — we work from any starting point.
Engineering review
Our team reconstructs missing geometry, validates fit, and recommends material and process.

Fixed quote within 24 hours. You approve CAD and material before anything is printed.
Produce & ship
Printed, post-processed and shipped in 3–7 working days. Rush available.
Materials & processes
Match or improve on the original
We select the process based on the part function — not by default.
- ABS / ASA (FDM) — cost-effective replacements for covers, housings, non-structural parts
- PA12 nylon (SLS / MJF) — durable functional parts, snap fits, brackets
- Polycarbonate (PC, PC-ABS) — impact resistance, higher temperature service
- ULTEM 9085 / 1010 — chemical, heat and flame resistance for demanding replacements
- TPU 95A — flexible spares: gaskets, bumpers, seals
- PETG — transparent covers, food-adjacent applications
- Metal (SLM / DMLS) — aluminium, stainless, titanium when polymer is not enough
Not sure which material matches your OEM part? Tell us the application (load, temperature, chemicals, UV exposure) and we will recommend the closest equivalent — or say if 3D printing is not the right answer.
Typical case
Discontinued laboratory-oven knob, 4 units
A university maintenance team was running four ageing lab ovens whose OEM control knobs had cracked. The manufacturer had discontinued the model 9 years earlier and no spares existed on the market. Quoted lead time from a specialist re-seller was 6 weeks — with no guarantee.
The customer sent us one broken knob and a photo of the shaft interface. Our engineers reverse-engineered the geometry in 4 hours, printed a fit-check in ABS overnight, and produced the final 4 units in glass-filled PA12 for stiffness. Total cost was approximately 78% cheaper than the OEM quote, and the parts shipped in 4 working days from first email.
When to use — and when NOT to
Be honest about the fit
Use 3D printed spares when
- The OEM part is discontinued or on long lead time
- You need 1–200 units of the same part
- The part is non-safety-critical plastic geometry
- You want a design improvement over the original
- You only have a physical sample, not a drawing
Do NOT use for
- Safety-critical parts (brakes, load-bearing structural)
- Regulated parts (aerospace certified, medical implants)
- OEM-certified replacements needed for warranty compliance
- Runs above 500 identical units — moulding is usually cheaper
- Standard hardware you can buy off the shelf
FAQ
Common questions about 3D printed spare parts
Yes. Send us the sample (or a good photo plus key dimensions, ideally with a calliper) and our engineers will reverse-engineer it. For complex geometries we 3D-scan the sample. You approve the reconstructed CAD before we print — no surprises.
Send us the broken part.
Drawing, STEP, scan, or a photo with a calliper — we take it from there. Technical quote in 24 hours.
