This course is about starting a 3D business. It won’t teach you complicated theory
I’m not an expert in 3D modeling, 3D printing or materials. I’m not an engineer, I’m not an artist, and I’m not really a creative person.
Instead, I’ve built several businesses. My latest e-commerce one, in the food sector, did $800,000 per year in my home country.
I know how to sell online and what people are willing to pay for. That’s what I’ll teach you.
I’m not going to teach you every single setting in the 3D printing software. Instead, we’ll focus on getting your first sale as fast as possible.
Hi! I’m Chris Barin, Adobe Certified & serial entrepreneur
You can find out more about me here, but in short: I specialize in web & app design. I’ve been teaching design on Udemy since 2013, where I’ve had the pleasure of working with over 300,000 students and I’ve received over 45,000 ratings.
You can see my LinkedIn page here, and you can listen to my life story in this audiobook, One Million from Photoshop.
My latest business is Ohvaz, a healthy food company in Romania that did $800,000 per year in sales, most of which came from my own website.

Questions, answered
Do I need any experience?
No. The course starts from zero: which printer to buy, which materials, what to sell and how to price it. You don’t need to know 3D modeling either.
Should I buy a printer before I start?
No. Watch the “Printers & filament” lessons first. They cover the best printers, the ones to avoid, and the expensive mistakes people make when they buy too early.
