    Really great printer – quality prints consistently. I recommend the heated bed upgrade too. The only downside I’ve found is that you can’t print without a raft due to the design, but that’s really not that big a deal 🙂

    I’m happy with the printer. The printing quality is good so far.
    Unfortunately, 2 of the printed parts provided with the printer were very badly manufactured.
    The leveling probe was bent (see picture), which made that the pressure sensor was not under the nozzle. Luckily I could rework it with a hot air gun.
    The cover for the electronics behind the Z axis was really ugly and totally deformed (unfortunately I threw it before making a photo). I draw and printed a new one, which is much better.

    The thing is great. First 3D printer I have owned. Only thing is I find that the auto generated supports are hard to remove, and I can only print with rafts on or the print slides around. Over all tho it is still great.

    So far I am amazed with what I can do with this machine! No adhesion for flexible filament! My only three problems with it are wifi connection gets lost a lot, impossible to print anything with a 0.6 nozzle (software/g-code error) and I can’t print at full volume – even PLA warps for no reason.

    Mostly seems ok i haven’t had the opportunity to use it yet but on assembling the printer found the small white electrical box on the back of the vertical arm broken I’m sure it won’t impact the function of it but it pisses me off none the less obviously the quality inspection person was asleep at the time !!!! The shipping and boxing of the equipment was excellent the box all arrived in tact.Anyway it looks good I’m sure ill have fun with this printer and it will be a learning curve as well as I’m new to this hobby as such, thanks to the Cetus people good job and keep on working to develop this little bugger even better.

    Hardware is very good, and it is the only printer on the market that is transportable. I travel every 3 weeks and just disassemble/ assemble it within 10 mins, pack it in the original package foam and move. However a bit lack behind competition in now considered standard, like heated build plate, auto leveling. It is upgradable but it should be standard in the first place.

    A fantastic machine for a good price.
    Printed faultless parts since the first day.
    I was surprised by the precision of the printed parts.
    Unfortunately not compatible with octoprint and therefore one point less.

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.”
