This 3D print farm case study looks at CruiseCup, whose 19-year-old founder Mike Satterlee says a farm of more than 160 printers helped him launch a double can cooler that brought in about $808,000 in 2025, according to CNBC Make It, CNBC’s personal finance and careers outlet.
The bigger lesson may be when to stop printing. In July 2026, CruiseCup switched its main product to stainless steel coolers made overseas, because keeping up would have meant buying ever more printers and space, he said.
Important: Income figures in this post are claims made by the creators in their own videos. I have not verified them, and they are not typical results or a guarantee. Most small sellers earn far less, and many lose money in year one.
The Product: A Double Can Cooler
Satterlee says he wanted to improve a standard can cooler. His design holds two cans and opens at both ends, so you can reach the second can after finishing the first. He learned 3D printing and design in a high school class, started selling his own designs online, and launched CruiseCup in May 2025.

| Item | Reported figure |
|---|---|
| Printers in the farm | Over 160, each with a 5 kg spool, printing around the clock |
| 2025 gross revenue | About $808,000 |
| Biggest 2025 expense | 3D printers and filament, about $117,000 |
| Print time per cooler | About 8 hours on average |
| Jan to Sep 2026 gross revenue | About $601,000 |
| Biggest 2026 expense | Inventory and molds, about $180,000 |
| Work week | 80 to 85 hours, he says |
How It Took Off: Going Viral
Satterlee says he posted a video of the cooler on social media, it went viral, and sales came right away. He took that as proof of product-market fit and decided to go full-time instead of starting college.
Copycats and Patents
As copycats appeared, especially for the 3D printed version, he says he filed two utility patent applications (patent pending) on the double can cooler.
Why He Moved Beyond 3D Printing
In July 2026, CruiseCup switched its main product from 3D printed to stainless steel coolers made overseas, after development that started in October 2025. His reasoning: to keep up, he would have had to keep buying printers, he was running out of space, and in the long run it would cost more than overseas manufacturing. He says he even had to stop selling before Christmas because he couldn’t fulfill orders, and that his biggest regret is not switching sooner. He orders on Delivered Duty Paid terms so tariffs don’t change his price.
Lessons for Anyone Starting a 3D Print Farm
- 3D printing is great for prototyping and validation. You can launch a product with no molds and test demand fast.
- It has limits at scale. An 8-hour print per unit caps output per printer, so growth means more machines, space and labor.
- Marketing drove demand. A viral social video mattered more than the printers.
- Protect a winning design. Copycats follow success.
- Plan the next step early. Molds or overseas manufacturing take months.
Choosing Printers for a Small Print Farm
Print farm owners on YouTube stress reliability and easy repairs over top speed. The YouTube channel Shop Nation, who grew from 2 to about 40 printers, runs mostly Prusa machines for that reason. The YouTube channel Sam Erickson built a small farm on one shelf with Flashforge Adventurer 5-series printers. Among the printers I cover, these fit:
| Printer | Price (Amazon, Oct 16, 2026) | Why it fits | Link |
|---|---|---|---|
| Bambu Lab P1S Combo | $549.00 | Reliable, enclosed; popular in small farms | Check price |
| Flashforge Adventurer 5M | $249.00 | Low cost per machine; used by some farm builders | Check price |
| Bambu Lab A1 | $299.99 | Low-cost way to test a product before scaling | Check price |
What YouTube Creators Found About the CruiseCup Print Farm
These are findings from popular YouTube videos, paraphrased from their transcripts and credited. They are the creators’ experiences and claims, not my test results.
- CNBC Make It (CNBC Make It: “I’m A Teen Who Built A Can Cooler Business — It Brings In $808,000/Year”) profiled Mike Satterlee and CruiseCup, including the print farm, his 2025 and 2026 figures, and his move to stainless steel manufacturing. All figures above are his as reported in the video.
- Shop Nation (Shop Nation: “10 Things I’ve learned running a print farm”) said there is nothing passive about a print farm: loading filament, monitoring, unloading and post-processing take real time at scale. He also stressed planning for breakdowns, heat and air quality, and recommended an air purifier near even a small farm.
- Sam Erickson (Sam Erickson: “Building a Mini 3D Print Farm // Is It Profitable?”) said filament is a small share of a farm’s costs, so cheap reliable filament is fine, and advised planning power circuits carefully as you add printers.
Frequently Asked Questions
How many printers does CruiseCup use?
Over 160, according to founder Mike Satterlee in the CNBC Make It video.
How much does CruiseCup make?

Why did CruiseCup switch to stainless steel?
He said scaling with 3D printers meant buying ever more printers and running out of space, and overseas manufacturing would cost less in the long run.
Is a print farm a good way to start a product business?
It is a fast, low-risk way to prototype and validate demand. For high volume, many businesses move to molding or manufacturing.
