This guide covers:

Belt 3D Printer Evolution – Brief History

3D printing was invented in the eighties, and later the Open-Source RepRap project gave a significant kick to it by building a self-replicating 3D printer. After that just in a dozen years, things went wild. Cartesian and delta 3D printers started to be mass-produced. Many more people got involved which led to a bigger contribution and further development of constantly evolving 3D printing. Conveyor belt 3D printers were introduced in the beginning of the last decade, but this type of machine only recently came under an intense spotlight.

A larger volume belt 3D printer, IdeaFormer IR3, became available on the market without a supporting crowdfunding campaign. This printer doesn’t have two profile supports and there could be some issues with stability, but the producer claimed that the structure is similar to Blackbelt 3D which proved to be stable. Some reviewers on Amazon praise the textured PU belt specifically for bed adhesion.

– Large Build Volume. The largest build volume in under $1000 price range for belt 3D printers.
– Semi-Assembled Kit. As the base comes assembled with the belt, it takes just over an hour, depending on your skills, to fully set the printer up.
– Other perks: Own developed hotend specifically for IR3. Silent mainboard, filament runout sensor, dual-gear extruder.

Blackbelt 3D Printer

Blackbelt 3D printer was the first conveyor belt 3D printer we encountered live on TCT Show Birmingham. A mini kayak was an impressive make. The cable management system, of a few meters long, showcased the novel infinite-z possibilities. We liked the one 3D printed in TPU, we could bend it.

As the price tag implies (EUR 9,500, January 2021) the blackbelt station, as it looks and feels like a station, was meant for professionals and workshops. Not many enthusiast makers and designers were able to try this machine out.

A small company, run by Adam Fasnacht, offers competitively priced custom-sized belts for DIY belt 3D printers or as an alternative/replacement belt for CR30 and other printers. Adam also runs a YouTube channel where he publishes an insighting videos about belt 3d printers in general.

Innovations Around Belt 3D Printer

In addition to the crowdfunding campaigns, we witnessed other innovative projects connected to conveyor belt 3D printers. Infinite Z opens the possibility to start uninterrupted production, giving hope to small businesses.


WASP, a delta 3D printers’ producer of all sizes, introduced the Automatic 3D Print Removal System for their Delta WASP 2040. Puzzled how could the belt works on a delta printer? Jump to a detailed blog with more pictures and videos.

Adam Fasnacht, a producer of the Powerbelt3D Formula32 belt, launched a Tinybelt 3D printer Kickstarter campaign. As the name says, it is a small printer, it also differs from other machines by having a singular angled Z-axis rail without a side frame. Tinybelt comes 90% preassembled. Unfortunately, the campaign was unsuccessful with 41% funded.

Transformable 2-in-1 Belt 3D Printer – 45° & 90°

What differs transformable printers from other belt 3D printers is that the added innovative feature can toggle between the belt 45° and the traditional angle printing modes. Such machines are designed with the ability to tilt the gantry to 90° for the traditional angle 3D printing. The switch between the two is quite easy. This feature gives the possibility to print long or multiple items and taller items on the same device. And who doesn’t like 2-in-1? Read more about the failed Infinity3D campaign to get an idea. Update: According to the comments on the campaign page, Infinity3D failed to deliver the product.

DIY Upgrade Kit for Ender 3

Michael Sgroi published on Thingiverse the files for upgrading Ender 3 to the so-called Enderloop. At the moment of updating this post, v2 files are available to download for free. It is recommended to buy the most crucial part – the Formula32 belt – from PowerBelt3D online store. To showcase his DIY project, Michael used Ender 3 and CR-6 SE 3D printers.

Wall Mounted Belt 3D Printer

An active Twitter and 3D printing community member @repkord installed his 3DPrintMills to the wall. This is a genially great idea to save space, especially if you run a 3D printer farm. In his mini video @repkord showcases how a belt 3D printer continuously produces identical parts. @repkord is very experienced in running 3D printer farms and this is just another case that proves that it is possible to run a business successfully with desktop 3D printers.

3D Printing with Pellets

An interesting know-how was described by Emmanuel Gilloz. Emmanuel installed a Mahor V4 pellet extruder on CR30 and tested various settings and materials, including 100% recycled PLA. The article is written in French and can be translated in Google.

3D printing using pellets is cheaper. In fact, 3D printing filaments are created from materials that have been originally in a pellet form. Another strong point about printing with pellets is recycling. By shredding existing prints and other used plastic products, like PET and PETG bottles, for example, could be resource-saving and environmentally friendly.

Where Conveyor Belt 3D Printers Can Be Used – What to 3D Print?

– 3D Printed Props. So far we’ve seen 3D printed swords as a game-changer for props makers. A real size sword can be sliced so it needs the minimal post-processing after 3D printing. One of the best examples is the sword 3D printed by Maker’s Muse.
– Big Letters. Filament Frenzy’s big letters were impressive. It is possible to 3D print letters one by one on cartesian (box) type 3D printers with better quality, though. But if the belt 3D printer can be tuned well, the whole process can be much easier.
– 3D Reliefs and Portraits. One of the remarkable prints we saw on Twitter was the scene from The Star Wars where Hans Solo was frozen in carbonite 3D printed by Polyworshop.

To list all goodies, that can be 3D printed on belt 3D printers, may need a new blog. Stay tuned as finally, such 3D printers hit the masses, and we are likely to see a lot of interesting makes and even innovations in the near future.
