As 3D printing become more popular, prices for 3D printers are dropping. Three days ago Canada based Rylan Grayson launched his $100 3D printer, and up to now his project has raised more than $287,762 CAD of $50,000 goal from 2,184 backers. There are many new ideas behind this project and by employing a new 3D printing method Grayson managed to keep the printer price as low as $100.

Resin based 3D printers are getting very popular this year. On Indiegogo there is a new Stereolithography printer in development which is quite unique. It is a small and foldable printer (measuring just 250 x 120 x 30mm when folded) that you can put in your your backpack or briefcase to travel with. And of course you wouldn't be able to make big objects, because it has only a building area of 90 x 90 x 90mm.

After being asked to develop a cheap, easy to use and portable 3D printer by a customer, Marin Davide started developing the LumiFold. The LumiFold is a resin-based 3D printer, where a laser fuses liquid resin into solid form. The cool thing is, you can use almost every projector with this light curing 3D printer. With LumiFold, an integrated UV sensor measures the exact UV light level of your projector and automatically adjusts the layer time.

Another special feature is the LumiFold also has interchangeable building platforms with an engraved grid, so you can also automatically adjust the projection for an accurate and correct size of your 3d printed parts.


  • Based on standard/cheap 20x20mm aluminum extrusion
  • Easy to use: just unfold, place under a projector, and print
  • Low energy consumption (approx. 5W)
  • Interchangeable resin bed and platform, including a smaller one for experimenting and printing small parts
  • Max Print volume 90 x 90 x ~90 mm
  • Z resolution up to 0.01mm

Davide also developed an open source program for slicing and printing for LumiFold. Another interesting feature of the LumiFold is its accessory, the HoloDock. The HoloDock is a 3D holographic display that shows the printing progress. And it can also be used alone to visualize 3d objects.

Davide's future plan includes adding 3D Laser scanning kit and travel kit with lithium battery and iPad / iPhone control kit to the LumiFold. If you find this project interesting, head on over to LumiFold's indiegogo page. A pledge of $390 will get you a LumiFold 3D printer and everything you need to start printing, excluding the resin. And an assembled version will cost $449.

Any idea when this will be available?

Great idea!

@PacoBell i think it depends on the beamer u use Thats why only Z resolution is given because thats trough the spindle/microstepping.

Holodock, I thought about it few days ago - every 3D printer should display the progress using the model and layers.

X/Y resolution?
