Popular Material Options
A practical choice for functional prototypes, covers, brackets, and parts that need more toughness than PLA.
Strong choice for durable functional parts, clips, brackets, housings, and low-volume components.
Good for early prototypes, concept models, and low-cost visual parts where speed matters more than durability.
Good for visual prototypes, concept models, and detailed parts that need smooth surfaces and fine features.
Better for functional prototypes with higher heat resistance, toughness, and a more engineering-plastic feel.
Useful for resin prototypes that need better handling strength while keeping good detail and surface quality.
Better for prototypes that need more durability during fit checks, reviews, and early functional testing.
Best for flexible parts such as grips, seals, bumpers, covers, and components that need bend or compression.
Good for soft-touch parts, flexible features, seals, grips, and prototypes that need some give.

Functional Parts and Prototypes for 3D Printing
We produce custom 3D printed parts for teams that need prototypes, test-fit components, shop tools, and selected low-volume parts. For design validation, assembly testing, or short-run production, our team can help match the part requirements to the right process before production.
Functional Prototypes
For parts that need to be handled, assembled, and tested during product development. Functional prototypes are useful for checking fit, ergonomics, mounting points, and basic performance before committing to tooling or production.
Jigs, Fixtures, and Shop Tools
For manufacturing aids, inspection fixtures, drill guides, alignment tools, and other parts used in daily operations. These parts are often practical when you need a custom tool quickly without waiting for machining or molding.
Low-Volume Plastic Parts
For short runs, pilot builds, spare parts, and limited-use components before tooling is justified. This is useful when you need real parts quickly but are not ready for injection molding or larger production commitments.
Test-Fit Parts and Assembly Components
For covers, housings, brackets, clips, mounts, and other parts that need to work with existing hardware. These builds help teams evaluate clearances, fastener locations, interfaces, and assembly behavior before moving forward.
Visual and Presentation Prototypes
For concept models, demo units, customer-review parts, and presentation prototypes where the part needs to communicate shape, scale, or product intent clearly. These projects may prioritize appearance, detail, or finishing depending on the use case.
Post-Processing and Surface Finishing
We offer finishing services for 3D printed parts, including polishing, sanding, and painting, depending on the material and geometry of the part. Not all parts or materials are suited for every type of post-processing, so we assess each project carefully.
If you need a specific surface finish, color, or aesthetic quality, let us know, and we’ll recommend the best solution based on your design and functional needs.
Our goal is to ensure that every finished part meets both visual and functional expectations, whether for testing, presentation, or final production use.
Take a Look Behind the Scenes of Our 3D Printing Process
We use only in-house 3D printing equipment so the work stays in one shop under a controlled schedule, without relying on third-party availability. This keeps the process end-to-end from setup through final handling, and it limits unnecessary handoffs for teams that prefer to keep designs confidential.

6. When should I choose Upside Parts instead of an online 3D printing marketplace?
Upside Parts is an engineering-first, in-house 3D printing partner. We can handle one-off parts and prototypes quickly, and we’re a strong fit when you also want one accountable team owning the build, quality checks, and timeline from start to finish. You get direct communication with the in-house team making the parts when questions come up. In-house production reduces handoffs and variability, which helps when requirements are tighter or when you need the same result again on repeat orders. Use self-serve quoting when your model is ready, or request optional DFM and material guidance when you want an expert review. A marketplace can be a good fit when you do not need direct access to the team making the parts. If you want a deeper comparison, read our guide on how to choose the right 3D printing partner for functional plastic parts.
7. Our files are sensitive. Can you sign an NDA?
Yes, NDAs are available if your team requires one. We handle uploaded files as confidential and limit use to quoting, production, and support.
