Sell on marketplaces
Sell from home, on Etsy, where the customer already shows up looking for something to buy. It costs 20 cents to list a product, so you can test a lot of ideas for almost nothing.

From printer to sale
Four decisions stand between your printer and your first sale
- 01
What to sell
Pieces with real demand, chosen before you hit print.
- 02
How much to charge
A price that covers filament, energy, failures and fees and still leaves a profit.
- 03
Where to sell
Locally, at fairs and neighborhood businesses, or online, through marketplaces and social media, each with its own margin and type of customer.
- 04
How to sell
The strategy that makes the sale happen in each channel, from the listing to the conversation with the store owner.
With these four decisions clear,
your printer becomes the start of a business.
Choose where to start
Three ways to sell your 3D prints
Each way has its own profile, its own margin and its own live course.
02
Sell locally
Sell face to face, at markets, craft fairs, store shelves and small businesses in your town. Every sale can be bigger, and the store keeps selling for you when you're not there.
Live course: Local Sales with Ashley Lee
03
Sell on social media
Sell live, on TikTok, Instagram and Facebook. The customer watches a video or a live, falls in love with the product, and buys right there.
Live course: Social Media with Mandi (Creation Circus)
Start with the path that fits you. Your access is for life, so you can open the second and the third whenever you want.

About the course
Sell your 3D prints face to face, and get paid the same day
Ashley Lee built a six-figure home bakery in Ontario, Canada, from nothing, with no business experience. She bought her first 3D printer less than two years ago and still sells with three, at markets, on a store shelf and to local businesses. In this live course, she shows you how to find the right place to sell and the right products to bring.
What you'll learn
- How to choose the right market, and why who's going to be there decides what you bring
- How to stand out when there's already a 3D printing booth (or five) at the market
- How to rent a consignment shelf and get paid on what sells
- How to sell wholesale to local businesses: one order, one pickup, one invoice
- How to price for retail and for wholesale without losing your margin
Who it's for: Makers who'd rather sell face to face, see the customer's reaction and get paid the same day.
