In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!
The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
So what’s new?
The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
The UltiMaker S7 also includes quality of life improvements:
Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more
Curious to see the S7 in action?
We’re hosting a free tech demo on February 7.
It will be live and you can ask any questions to our CTO, Miguel Calvo.

Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
We are actually in the midst of updating the Ultimaker technical datasheets, so I can help you out a bit with your question.
Ultimaker Nylon is a PA6/66 copolymer, like Polymaker's CoPA (also PA6/66). Colorfabb PA neat is mostly PA6 as far as I know.
What does that mean for you in terms of mechanical properties?
Typically PA6/66 is a flexible yet very strong and tough Nylon, with a tensile modulus of about 2300 MPa and flexural modulus of 1900 MPa. The same applies for Ultimaker Nylon as well as Polymaker's CoPA.
Tensile strength is very high for such materials, typically 60 MPa with yields of about 6%. Also, this nylon will typically elongate up to 120% before it breaks (so double it's length).
Flexural strength is also rather high at 80 MPa.
PA6 (e.g. Colorfabb) is stiffer compared to PA6/66, typically a modulus of about 3000 MPa. Strengths are slightly higher as PA6/66, but it basically doesn't yield but it breaks instead of extending - so it depends a bit on your application.
As a side-note, numbers that I just give for Ultimaker Nylon are actually measured on 3D printed parts. Filament suppliers typically just use injection molding values - which are ideal cases. Expect only 80~90% of the reported properties of such TDS (at least in our experience).
Hope this helps!

Thank you. Your answer is what I was looking for. I had been indecisive about several materials, but I am going use UM's nylon. One thing I have noticed is that I'm more likely to run into situations where the hobbed gear chews out a bit of the filament and the filament quits moving. It's usually preceded by the material failing to unload from the hot end at the end of the print. This results in the next print not starting properly because the nylon doesn't extrude. The prints where the material fails to unload are fine. I think what is happening is that the nylon is getting slightly stuck in the hot end because it is cooling too much at the end of the print and this causes the hobbed gear to chew up the filament. I clear it up by following the steps on the display, but not really. I let the hot end heat up and then the nylon retracts just fine. I lie to the printer by not actually removing any of the tubing. This is on an S5 with a Material Station. Any ideas?
