Client Reviews
★★★★★
PrototyperLab were quick and efficient — had our first prototype ready in just two weeks. The whole process was low-risk, making it easy to test new products with our existing customers. At first, I thought we’d use them for development and then move mass production to our factory in China, but their pricing was very competitive. Keeping production with PrototyperLab meant better quality control and ongoing improvements, so there was no reason to take the risk of moving it elsewhere.

We found PrototyperLab through a recommendation from another brand, and to be honest, we weren’t sure what to expect. We shared one of our new product ideas and its use case, and within a few days, they had a physical plastic prototype ready. I was seriously impressed. The pricing is super reasonable, which means we can test out even more product ideas, especially those with electronics or automation. It’s a huge time-saver for us, letting our team focus more on launching and marketing instead of getting stuck in long development cycles.

We wanted a functional, expandable robot that didn’t blow our budget. PrototyperLab helped us make it real — fast. 690 engineering hours covering hardware, firmware, and a 150-hour STEM curriculum developed alongside the product. The 20-unit production run validated demand before we committed to scaling.

Superb company and service. Tai and his team have been super helpful, responsive and hands on in assisting with prototype design and production, rapid turnaround on queries and fairly priced. I continue to use them beyond the initial services I engaged them on. Trust worthy and reliable. Highly recommend

Our Guarantee
We believe in fair, transparent, and results-driven partnerships. Here’s what you can count on.
01
Getting a quote is fast, hassle-free, and completely risk-free. You won’t pay a dime until you approve the full project estimate.
02
If we take longer than the quoted hours to complete your project, you won’t pay for the extra time. The quoted hours are the ceiling, not an estimate.
03
We don’t just build prototypes — we ensure they function as intended before delivery. You receive a working product, not a visual model.
04
Your prototype will be in your hands within the agreed timeline. If something changes on our end, we tell you immediately — not after the fact.
05
We don’t mark up material or production costs. Our entire profit margin comes only from our engineers’ $25/hr rate. Materials are passed through at cost.
06
We are a US-registered company. All contracts and payments are handled within the US, so there’s no risk of dealing with international disputes or unenforceable agreements.
07
You approve CAD designs, prototype photos, and production samples before we proceed to the next stage. No stage begins without your sign-off. No black boxes, no surprises.
08
Your project gets one or two dedicated engineers from start to finish. No sales reps, no account managers, no communication layers — just you and the people actually building your product.
You do. Ownership is entirely yours from the moment the final invoice is settled. We hold it in storage for your production runs at no charge.
Yes. We can ship your mold to any factory worldwide at any time. No restrictions, no contractual holdbacks.
Aluminum molds cost less and build faster but wear out after 1,000 to 10,000 shots — best for small batch validation. Steel molds cost more and take longer but last 100,000+ shots — best for confirmed demand and volume production.
Submit your design files (STEP, IGES, DXF, or PDF drawings), target material, surface finish, and quantity. We send back an itemized quote within 48 hours.
Steel mold manufacturing: 4 to 6 weeks. First article sample review: 1 to 2 weeks. Production run and shipping: 2 to 3 weeks. Total: approximately 7 to 11 weeks from quote approval to delivered parts.
