Children’s Products and Toys Prototyping and Small Batch Production

Build Your Children's Product or Toy Idea — Safely and Compliantly

From concept to a tested, certified prototype. We design and build children’s products and toys with CPSC compliance built into the process from day one, not bolted on at the end.

Children's products and toys like what you are thinking of building

Three real products built by solo inventors, small teams, and our own client work. Every one needed real engineering, real safety testing, and real manufacturing discipline before it reached a child’s hands.

Example 1 — modular STEM robotics / education hardware

Torotic — a modular robot that lets kids upload code and watch it run in real time

Torotic set out to solve a real problem in children’s coding education: students write code but rarely see it work in the physical world. PrototyperLab supported Torotic through concept, electronics design, firmware, 3D-printed enclosures, and a custom Blockly integration. The CenterCube Core Unit serves as the modular hub with plug-and-play sensor and output modules.

690 total engineering hours: 360 on hardware, 70 on firmware, 260 building a 150-hour STEM curriculum. 20-unit minimum production run to validate demand.

“We wanted a functional, expandable robot that didn’t blow our budget. PrototyperLab helped us make it real — fast.” — Torotic founder

Hardware: 690 engineering hours  |  Modules: CenterCube + plug-and-play  |  Curriculum: 150 hours

Example 2 — creative tool / STEM toy

3Doodler — a 3D printing pen born from a printer's mistake, now over 1.4 million units sold

Max Bogue and Peter Dilworth were 3D printing a robotic dinosaur leg when their printer skipped a line. One of them joked that you could just take the nozzle off and fill the gap by hand. Nothing like that existed, so they built it.

Launched on Kickstarter in 2013 with a $30,000 goal, raised $2.3 million from over 26,000 backers. A second campaign in 2015 raised another $1.5 million. They later released the 3Doodler Start — a completely kid-safe version with cool-touch, non-toxic plastic built specifically to meet the safety bar for a children’s product. More than 1.4 million pens sold.

Kickstarter: $2.3M, 26,457 backers  |  Kid-safe version: cool-touch, non-toxic  |  1.4M+ units sold

3Doodler — a 3D printing pen
GoldieBlox — a hand built prototype of wood, thread spools, and clay

Example 3 — construction toy / injection-molded plastic

GoldieBlox — a hand-built prototype of wood, thread spools, and clay became a Toys R Us shelf product

Debbie Sterling, a Stanford-trained engineer, built her first GoldieBlox prototype by hand using wooden blocks, thread spools, clay, and velcro, then tested it with girls in the Bay Area. She took the validated design into CAD and found a factory for injection-molded plastic parts. The minimum run was 5,000 units — more than she could fund alone.

She launched on Kickstarter to cover it. The campaign hit its $150,000 goal in 4 days and raised $285,881 from 5,519 backers. The video went viral, demand pushed the first production run from 5,000 to 40,000 units, and GoldieBlox went on to sell in Toys R Us and Amazon.

Kickstarter: $285,881 in 4 days  |  Production: 5,000 to 40,000 units  |  Retail: Toys R Us, Amazon

How it works

01

Share your idea and fill out our questionnaire

A sketch, photo, or description. Target age range and any electronics, small parts, or materials involved. We flag likely CPSC requirements before any design work starts.

Brief and compliance scope confirmed within 24 hours

02

Get your itemized quote within 48 hours

Design, materials, fabrication, electronics, and finishing. If third-party testing applies, we include that cost and timeline up front.

Quote with timeline, milestone plan, and testing scope

03

Pay your deposit and we start work

50% deposit locks in your project. Milestone updates at CAD review, build, and finishing. We coordinate sample submission to our accredited testing partner as part of the build.

Prototype and test-ready samples in 25 to 45 days

Compliance and Safety Testing

CPSC Certification and Testing, Handled for You

Every children’s product sold in the United States must be tested by a third-party, CPSC-accepted laboratory and certified with a Children’s Product Certificate before it can legally ship. We work with an accredited CPSC testing lab partner so you don’t have to find, vet, and manage that relationship yourself.

What gets tested

What you receive

We scope likely testing requirements at the brief stage, before you commit to a design, so certification costs are part of your quote from the start. Federal law requires every children’s product to be tested by a CPSC-accepted lab before sale in the US, regardless of where it is manufactured.

Client Reviews

What our clients say

Our Guarantee

What we promise on every project

We believe in fair, transparent, and results-driven partnerships. Here’s what you can count on.

01

No upfront payment until you approve the quote

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

No extra charges for delays on our end

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

A fully tested, working product

We don’t just build prototypes — we ensure they function as intended before delivery. You receive a working product, not a visual model.

04

On-time delivery

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

No hidden fees in production

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

US-based contracts and legal protection

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

Milestone approval, every step

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

Direct engineer access on every project

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.

Frequently asked questions

Nearly all products designed or intended primarily for children 12 and under require third-party testing and a Children’s Product Certificate before they can be sold in the US. The specific tests depend on your product’s materials, age grading, and features.

A Children’s Product Certificate (CPC) is required for products intended for children 12 and under and must be based on testing from a CPSC-accepted third-party lab. A General Certificate of Conformity (GCC) applies to general-use products and does not always require third-party lab testing.

Registered small batch manufacturers may qualify for relief from certain testing requirements (Group B rules) if they meet CPSC’s revenue and unit thresholds. This does not exempt lead, phthalate, or core toy safety testing.

Typical turnaround is 2 to 4 weeks once samples are submitted. Cost varies by product complexity. We include estimated testing cost in your quote.

Yes. Electronics-integrated children’s products require additional testing for battery compartment security, button cell battery rules, and electrical safety on top of standard toy safety testing. We scope this during the brief stage.

Yes. We build and approve a working prototype first, then submit final production-representative samples for testing once the design is locked.
