    I first saw this printer with a friend. She came to work with me to brag. I also have 3 printer models, of which Prusa, Delta and one SLA type. Although I had printed many models at that time, I was very impressed by the prints made by my friend with a Cetus 3D printer model MKII. This made me buy a standard MKIII printer. I am very satisfied with the quality of the printer. I also decided to buy the update packages for it, namely the digital screen and the heated bed together with the automatic leveling sensor. I warmly recommend the purchase! I will come back with new comments after I upgrade my printer.

    Works pretty well. A little loud, seeing as I keep it next to my bed at night, but not that big of a problem since I’m a heavy sleeper.

Cetus MK1 & MK2 Reputation

Cetus 3D Printer was born to be a minimalist 3D printer for you and ourselves. Equiped with stainless steel linear rails, gives high precision, stable printing, small footprint and quiet operation make it an ideal desktop 3D printer.

Before Cetus MK3 was released, its previous version – Cetus MK1 & MK2 has gained a good reputation from market.

In September 2016, Maker’s Muse, one of best 3D Printing Youtube Channel, released the first review for Cetus MK1 Pre-production version before we launched the successful Kickstarter Campaign in 2017.

In December 2018,  Maker’s Muse threw the challenging Christmas Lattice Torture Test at 5 of his 3d printers to see how they handled it. The results were WILDLY different. How Cetus MK2 performs? Check it!

In June 2019, Cetus 3D Printer is picked again by Maker’s Muse as “My TOP 3D Printers for the 2019 Maker’s Muse Studio (FDM/FFF)“. “The Mark 2 & 3 get a lot of use, I actually printed my sliding puzzle completely on the Mark 2. Believe it or not, all the moving parts printed fantastically.”
