Earlier this year, start-up Kast3DP showed off their new Kast 3D printer at the HAXLR8R Hardware Accelerator Demo Day. The Kast is a stereolithography 3D printer that allows you to construct high-quality 3D plastic objects in a matter of hours. Stereolithography (SLA) is one of oldest methods used to create 3D-printed objects. SLA technology 3D prints objects by hardening liquid plastic (photopolymer) with an ultraviolet light (UV). This is done layer by layer to convert convert liquid plastic into solid objects.

The company informed us today that they are currently working on the first prototype of the Kast 3D Printer for mass production. This current version features a build speed of 5 inches (127mm) per hour, which is a lot (from five up to twelve times!) faster than other SLA/DLP-based desktop 3D printers currently available (obviously depending on the type of model produced). As Dan Myung of Kast3DP explained to 3ders.org, "we have achieved this speed and resolution by employing a new approach to cure resin". They have named this approach as "RetinaKast". He went on to state that "in this process, we employ a speical panel as a mask in directing light to cure resin one layer at a time."

The Kast also has a large build volume of 9.7" (246mm) in diameter x 10" (254mm) in height. Its 96 micron resolution allows you to print object with a smooth finish, that require no post-processing work.

Even 3D printed lenses should be possible with Kast 3D printer.


  • Technology: RetinaKast SLA
  • Build speed: 5 in/hr
  • Layer resolution: 96 microns
  • Software: B9-Creator Based
  • Connectivity: Wi-Fi, PC/iOS/Android
  • Chassis: Aluminum
  • Windows: Acrylic
  • Build platform: Glass
  • Weight: 8 kg

The Kast3DP company plans to launch a Kickstarter campaign for their Kast 3D printer later this month. They are sorting out the other Kickstarter details at the moment, but they have already revealed that early adopters will be able to get a Kast for as low as $999, although this offer will be limited to 25 backers of their crowd-funding campaign.


The company requests not to reveal its method before Kickstarter campaign. We hereby replace its approach with a word 'RetinaKast' provided by the company.

Don't miss out on your chance to win a Kast printer even BEFORE Kickstarter backers get theirs, in the 3D Printed Creature Design Contest on now

I would like to know if the LCD is user replaceable for the inevitable dead pixel situation.

So finally a company is going to use LCD, I was wondering when the first company was going to do this. It's actually also a shame that plasma technology is dead too as it would have been a perfect fit for uv resin printers. Plasma tv's generate uv rays which are transformed into color by gasses that are inioned. For a 3d printer you don't even need these gasses or special filtering layers, it would be much cheaper than a normal plasma screen.
