Turn a CAD file into a part you can hold — usually within 2–7 business days. Rapid prototyping lets you validate fit, feel, and function before you commit to tooling or production, so problems get caught when they're still cheap to fix. Whether you're an early-stage hardware startup, an established Rochester manufacturer testing a redesign, or an inventor with a single idea, the goal is the same: shorten the loop between "I think this works" and "I know this works."
What's included
- Free design-for-manufacturing review on every quote so we can flag weak walls, unsupportable overhangs, or hole sizing issues before we print.
- Material recommendations matched to how the prototype will be used — a visual mockup, a load-bearing test piece, or a drop-in for an existing assembly.
- Iteration support — tweak the file and reprint, usually same-week, so your design cycle keeps moving.
- Dimensional check before parts leave the shop, so a fit prototype actually fits.
Technologies we use
Most prototypes come off one of two processes, and picking the right one early saves a reprint:
- FDM — Fused Deposition Modeling. Our default for functional prototypes: engineering plastics (PETG, ABS, ASA, nylon, PC), larger build volumes, lower cost per part, and real mechanical strength for fit-and-function testing. Run on Bambu Lab X1 Carbon and Prusa MK4S printers.
- SLA — Stereolithography. For prototypes that need fine detail or a smooth finish straight off the printer: small enclosures, jewelry masters, dental and miniature work — anything under roughly 100 mm where surface quality matters more than load-bearing strength. Run on a Formlabs Form 3+ resin printer.
Not sure which fits? Send the part with your quote and the free design review will include a recommendation. If you need an FDM-vs-SLA primer first, our FDM vs SLA guide walks through strength, detail, speed, and cost, and our design-for-3D-printing tips cover the choices that most affect how a prototype turns out.
Typical use cases
- Proof-of-concept parts for investor pitches, customer demos, and crowdfunding photography — something tangible beats a render every time.
- Fit checks against existing hardware, enclosures, or assemblies, where the only way to be sure a bracket clears a connector is to hold both in your hands.
- Functional prototypes for mechanical, thermal, or ergonomic testing — snap-fit tolerance trials, grip studies, heat-soak checks in real engineering plastics.
- Pre-tooling validation before committing to injection molding, so a $10,000+ mold is cut around a geometry you've already proven.
- Iterative design refinement — print revision A, test it, mark it up, print revision B the same week. Most of our prototyping customers run three to five cycles before they freeze a design.
A real example from our shop: a Rochester consumer-electronics startup needed eight presentation-quality enclosures in under two weeks for a Kickstarter launch and a CES demo. Over four sub-48-hour iteration cycles we refined the enclosure around their PCB, added integrated cable routing, and proved the snap-fit tolerances on FDM before switching to SLA resin for the photo-ready final units — delivered in 12 days.

What we need from you
A CAD file in STL, STEP, OBJ, 3MF, F3D, or IGES format is ideal. No CAD? A dimensioned sketch, a photo with a ruler in frame, or the physical part you're replacing all work — we also offer custom design and reverse engineering if the model needs to be built or rebuilt first. Tell us how the prototype will be used (visual only, fit check, load test) and which dimensions are critical, and the design review will be tailored to that.
FAQ
How fast can I get a prototype? Standard turnaround is 2–7 business days from approved quote. Small single parts are often quicker; mark "ASAP" on the quote form for rush options with same-day or next-day pickup in Spencerport when schedule and material allow.
Will my prototype be strong enough to actually test? If you print in the right material, yes. FDM in PETG, ABS, ASA, nylon, or polycarbonate produces parts strong enough for real functional testing — not just display models. We'll recommend a material based on what the part has to survive.
How accurate are the dimensions? FDM holds roughly ±0.2 mm (or ±0.2% on larger features); SLA does better on small parts. For critical fits we'll adjust feature sizes to match your hardware, and we dimensionally check parts before they ship. Our guide to 3D printing tolerances covers what to expect and how to design for it.
Turnaround
Most prototypes ship in 2–7 business days. Rush options are available when a deadline is tight — just mark "ASAP" on the quote form and we'll confirm feasibility and pricing in your quote reply.
