FAQs
What is functional 3D printing?
Functional 3D printing focuses on parts designed to be used, not just displayed.
At Light Rae Customs, functional printing means parts that are engineered to fit properly, handle real-world loads, and perform reliably in daily use.
This includes replacement parts, mechanical components, and custom solutions where off-the-shelf options fall short.
What types of custom 3D printing projects do you offer?
Light Rae Customs specializes in:
Discontinued or hard-to-find replacement parts
One-off custom components
Functional upgrades and design improvements
Prototypes and fit-test parts
If the part needs to install, align, and work as intended, it’s the type of project I focus on.
Can you recreate a discontinued or broken part?
Yes. Replacing discontinued parts is one of the most common requests I receive.
Using a broken sample, measurements, photos, or even a rough description, I can often reverse-engineer a functional replacement designed for proper fit and long-term use.
Do I need CAD files or technical drawings?
No.
Many customers start without CAD files. You can provide:
Photos
Measurements
A broken original
A description of how the part functions
I handle the design work and refine the model as needed.
What materials do you use for custom 3D printed parts?
Material selection depends on the application. Parts may be designed using materials chosen for:
Strength and durability
Heat resistance
Impact resistance
Dimensional stability
Each project is evaluated individually to ensure the material fits the real-world demands of the part.
How strong are 3D printed replacement parts?
When properly designed and printed, 3D printed parts can be very strong and reliable.
Strength depends on:
Material choice
Print orientation
Wall thickness and internal structure
How the part is loaded during use
Parts are designed with these factors in mind to ensure dependable performance.
Can you improve an existing part design?
Yes. In many cases, I improve upon the original design by reinforcing weak points, adjusting tolerances, or optimizing geometry.
The goal is not just replacement — it’s creating a better-performing solution.
Do you ship custom parts nationwide?
Yes. Light Rae Customs is based in Macomb County, Michigan, and ships custom parts to customers throughout the United States.
How long does a custom 3D printing project take?
Timelines vary by complexity, but most projects follow this general process:
Design and review: a few days
Printing and finishing: a few additional days after approval
You’ll receive a clear estimate before work begins.
Do you sell pre-made products as well?
Yes. You’ll find a selection of repeatable, ready-to-order products in the shop.
That said, many functional parts are one-off solutions, which is why custom project requests are encouraged.
How do I start a custom 3D printing project?
You can start by submitting a custom project request with:
Photos or measurements
A description of the problem
Any relevant details about fit or function
You don’t need perfect information — just enough to explain what you’re trying to solve.
