From 3D Scan to Finished Replacement Part

When a plastic or metal component is discontinued, cracked, or impossible to source, I can capture it with 3D scanning, rebuild it in CAD, and deliver a functional replacement by 3D printing or machining.

Ideal for industrial equipment, classic vehicles, specialty machines, and any application where one missing part is holding everything up.

When this service makes sense

This page is for situations where a part has to exist, but the original manufacturer does not offer it anymore, lead times are unacceptable, or drawings simply do not exist. Instead of retiring a machine or parking a vehicle over one broken component, you can have that part recreated with modern tools.

An industrial machine is down because a small plastic housing or bracket broke.
A classic or specialty vehicle needs an interior panel, duct, knob, or cover that is no longer sold.
Legacy equipment has brittle injection-molded parts that keep cracking under normal use.
You need a short run of parts before committing to new tooling or redesign.

If you can send the original part — even cracked or incomplete — there is a good chance it can be scanned, reconstructed, and returned to you as a functional replacement.

Typical applications include:

Injection-molded housings Covers and shrouds Ducts and manifolds Mounting brackets Switch and gauge bezels Cable guides & retainers Sensor and connector blocks

How the scan → CAD → replacement workflow works

1. Send the original part

Even if it is cracked or worn, the original part provides the best reference.

2. High-resolution 3D scan

The part is scanned to capture its full geometry and critical surfaces.

3. CAD reconstruction

The scan is converted into a clean CAD model; weak points can be reinforced.

4. Prototype fit check

For complex parts, a quick prototype may be printed to confirm fit.

5. Final part

The final replacement part is 3D printed or machined in the appropriate material.

Materials and options

Each replacement part is matched to a material that suits its environment and load.

Engineering plastics: tough, heat-resistant options for functional components.
Filled polymers: reinforced materials for stiffness and durability.
Metals: aluminum, stainless, and other alloys for demanding applications.

Rush service is available for some 3D-printed parts depending on geometry and material choice.

What I need from you to get started

The fastest way to get a replacement quote is to send a few details and photos. If the project is a good fit, you’ll receive next steps and an estimated cost before shipping anything.

Photos of the part from multiple angles.
Approximate size or any critical dimensions.
A note describing what the part does and how it failed.
Whether you need one replacement or multiple.
