A Photographer Turned 3D Printing Entrepreneur Is Making Full-Time Income on Portals

Luke Edwin does not run a Shopify site. He does not pack boxes or stand in line at the post office. The 110,000-subscriber photography YouTuber simply uploads a 3D model to Slant 3D's Portals marketplace, sets a price, and collects profit while someone else prints, packs, and ships every order.

That model has turned a weekend project into his single biggest income stream.

From Side Project to Full-Time Business

Edwin designed a macro lens adapter for the Insta360 GO Ultra camera. He published the 3D file as a free download and made a video about the project. The video pulled in more than 20,000 views, and viewers without 3D printers started asking how they could buy one.

Portals launched about a month later, and Edwin listed the adapter within minutes. Within days he had sold hundreds of units. He did not have to source filament, calibrate printers, or write a single shipping label. Slant 3D handles all of it.

Why Portals Changes the Math

Traditional 3D printing businesses require capital for machines, space for print farms, and time for fulfillment. Portals removes all three. Designers pay only the production cost when a customer buys something. There are no listing fees, no subscriptions, and no monthly minimums. If nothing sells, the creator owes nothing.

The platform is built on Slant 3D's existing Teleport print-on-demand infrastructure, which already supports thousands of businesses through Etsy, eBay, and Amazon. Portals wraps that same backend in a simpler interface aimed at creators who just want a product page and a payment link.

The Creator-Friendly Setup

Edwin's operation is deliberately small. He designs the product, records the video, and drops the portal link into his YouTube description. The rest is automated. Slant 3D prints the parts, applies finish choices like marble or color-matched filament, packs the order, and ships it to the customer. Edwin keeps the profit margin he sets at the start.

There is no customer support queue, no return processing, and no inventory sitting on a shelf losing value. The macro lens adapter is a simple plastic part, but it is the kind of niche product that sells consistently because it solves a specific problem for a specific audience.

What This Means for Designers

The barrier to selling physical products has dropped to almost nothing. A designer with a model library can list multiple products in an afternoon. A YouTuber with an engaged audience can turn downloads into revenue without changing their workflow. A small brand can test demand before investing in tooling or warehousing.

The catch is visibility. Portals is a marketplace, not a guaranteed audience. Success still depends on driving traffic from somewhere else: YouTube, Instagram, TikTok, or an existing community. Edwin already had that audience. For creators who do not, Portals is a fulfillment backend, not a marketing channel.

The Bigger Picture

3D printing has promised on-demand manufacturing for years. Portals is a concrete implementation of that promise: a designer files a model, a print farm makes it, and the end user gets a finished part without any intermediate steps. It is not going to replace injection molding for high-volume commodity parts, but for low-volume, high-variation products, it is a workable path.

Edwin's case is not an outlier. Slant 3D says it has supported more than 4,000 businesses through its print-on-demand services. The question is whether that number grows as more creators discover that the hardest part of manufacturing is no longer making the part. It is getting someone to buy it.
