Quick answer
To get a 3D-printed replacement for a broken or obsolete machine part, send 3DadditHub a photo, sample or drawing. Our engineers reverse-engineer the part if needed, quote it within 24 hours, and produce a functional replacement in PA12, PC, ABS, TPU or metal. Standard polymer replacements ship in 24-72 hours — versus 6-12 weeks from the original OEM.
What we manufacture
Parts we print for maintenance teams
Concrete replacements MRO buyers and maintenance engineers send us every week.
- Obsolete machinery parts from OEMs that discontinued the SKU (guards, knobs, levers, covers)
- Damaged safety guards and machine covers replicated from the surviving pieces
- Custom sensor mounts and brackets for retrofitted proximity, laser or vision sensors
- Replacement plastic clips, snap-fits and cable connectors when OEM won't quote < 100 units
- Cable routing channels, drag-chain adapters and grommets for control cabinets
- Custom brackets to replace failed OEM parts with an improved design (thicker walls, ribbed)
- Housings and enclosures for retrofit sensors, PLCs and small electronics
- Wear parts and bushings in engineering polymers (PA12, PEEK, POM equivalent)
- Line-side jigs and locating fixtures adapted to worn or replaced tooling
How teams use us
From downtime call to shipped part in four steps
Send what you have
Ship the broken part, or send photos + calipers dimensions of 3-5 critical features. A drawing or STEP file skips reverse engineering entirely.
Engineering review + quote
An engineer reviews feasibility, proposes a material equivalent to the failed OEM part, and sends a firm quote in under 24 hours. Reverse engineering priced separately if needed.
Produce
Print in PA12 (SLS/MJF), ABS, PC, TPU or metal. Standard QC includes dimensional check on critical mating features and visual inspection.
Express ship
Packed and shipped via DHL / UPS / FedEx, express available. For repeat MRO parts, we archive the file — reorders skip the quote step.
Materials & processes
What we would suggest for a maintenance replacement
Process choice is driven by the failure mode and the environment the part sits in.
- Durable general-purpose polymer parts (guards, covers, brackets): PA12 in SLS or MJF — see /technologies/sls and /technologies/mjf
- Cost-optimised replacements for non-critical parts: ABS or PETG in FDM — /technologies/fdm
- Impact + temperature-resistant covers and enclosures: Polycarbonate (PC) or PA12-CF
- Flexible seals, bumpers, gaskets and cable strain reliefs: TPU 95A
- Wear parts, low-friction bushings, guides: POM-equivalent or PEEK for aggressive environments
- Structural or load-bearing metal replacements: SLM/DMLS in aluminium AlSi10Mg or stainless 316L — /technologies/metal-printing
- Corrosion or chemical exposure: PP or PA12 with chemical-resistant coating
Typical case
Discontinued packaging-line guard, 36-hour turnaround
A food-packaging plant had a 320 x 180 mm ABS safety guard shatter on a Monday morning. The OEM had discontinued the line 4 years earlier and quoted 9 weeks for a one-off replacement at €620. Line downtime cost: €4,800 per shift.
The maintenance engineer photographed the surviving pieces, taped them together for reference, and sent us dimensions on the four mounting holes and the overall envelope. We rebuilt the CAD in 2.5 hours (€210 engineering), printed the guard in MJF PA12 with a 10% thickness increase on the ribbed sections (€195), and shipped express Wednesday morning. Total: €405, delivered 36 hours after first contact. The digital file is now archived for the next failure.
Common pain points solved
Before us vs. with us
Before
- • OEM says the part is discontinued or 8-12 weeks out.
- • OEM won't quote fewer than 50-100 units.
- • No drawing exists — only a broken sample.
- • Downtime cost dwarfs the cost of the actual part.
- • Maintenance team hoards spares "just in case."
- • Line stays down waiting for a cargo shipment.
With 3DadditHub
- • 24-72h turnaround on a functional polymer replacement.
- • Minimum order = 1 piece. No MOQ headaches.
- • We reverse-engineer from your broken sample.
- • Digital warehouse — reorder by part number, no re-quote.
- • Just-in-time production. No shelf inventory needed.
- • Express air freight standard, weekend production on request.
FAQ
What maintenance managers and MRO buyers ask us
Yes. Ship us the broken part (or the pieces of it), and we reverse-engineer it into a printable CAD model. Depending on complexity, we use direct measurement with calipers, 3D scanning for organic geometry, or both. You get an editable STEP file plus the printed replacement, so future runs are cheap. Typical engineering effort: 1-4 hours at €60-120 per hour. A simple bracket or clip is usually under €200 in engineering; a housing with internal features 4-10 hours. The physical part is quoted separately based on process and quantity.
Get a functional replacement in 24-72 hours.
Send a photo, sample or drawing. An engineer reviews it, proposes a material equivalent to the failed OEM part, and comes back with a firm price and lead time in under 24 hours.
