When the Garage Competes with Industry: Inova MK1 Arrives

The Czech team from SLS4All has decided enough of playful FDM printers and presents the Inova MK1: a real SLS printer for serious makers 💪. With a 10W laser, professional thermal control, and ability to work with powders like PA12, this open-source beast proves that laser sintering is no longer just for labs with astronomical budgets 🔥.

"It's not a project for beginners, but if you know what you're doing, you'll have a professional SLS for a fraction of the industrial price," warn its creators.

Specifications that Take Your Breath Away

This machine doesn't play at being professional - it is:

Safety First (Because the Laser Doesn't Forgive)

The Czech engineers didn't skimp on protections:

Two Ways to Suffer... I Mean, Build It

You can choose:

  1. Complete Kit: For those who want everything served
  2. Hardcore Mode: Just the essentials, you make the rest

The software based on Klipper and controlled by Raspberry Pi 5 allows adjusting every last parameter, because in the maker world, freedom hurts... but it's worth it. That said, if something fails, you can't complain to technical support - you'll have to roll up your sleeves and fix it like a true maker 🛠️.

So now you know: if you've always wanted an SLS but your bank account disagrees, the Inova MK1 might be your solution. Just remember - with great sintering power comes great responsibility... and probably many weekends lost adjusting galvos 😅.
