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.
On the older spools that I have, the material is indicated: PS (=polystyreen). Other spools might be ABS, PC,... But I don't know about the newest spools.
So yes, these old spools should be recyclable perfectly. (But I am not an Ultimaker representative, just a user, so this is not official.)
But even if the spool would not be recycled, but only recollected in the general "rest" fraction of garbage, and be burned, it is probably still way more environmentally friendly than glass or cardboard.
Cardboard requires killing lots of trees to produce it. And glass requires at least 100x more energy to melt than plastic. And you don't get any energy back from glass at the end of its lifecycle (which for glass bottles is only 6x re-use, plus a lot of dangerous chemical cleaning liquids in-between each cycle).
Modern burning-installations use the heat from burning garbage to produce electricity and warmth for heating buildings, or for industrial processes (for which otherwise other energy sources would have to be found). The exhaust gasses CO2 and H2O (carbondioxide and water vapour) are food for the plants and trees.
Today there is not enough CO2 in the air, only 0.03% to 0.04%, and most plants are on the edge of extinction. Below 0.02% CO2, all plant life dies. Ideally, there should be between 4x and 10x more CO2 for optimal plant growth, than now. Yes, way more CO2, not less. Which is scientifically proven in large scale research projects, and even in every greenhouse: they inject a lot of CO2 in their greenhouses to increase growth and production.
The rule is: 10x more CO2 gives 6x to 7x more green, without you needing to do anything. Plants grow by themself. Then all deserts world-wide would become green again, automatically. The problem is not "lack of water" in the deserts, no, the problem is lack of CO2 to enable plant growth. If there is 10x more CO2, then plants don't have to open their pores as much to breathe in enough CO2, so they don't evaporate and lose as much moisture. Then the current amount of water in the desert is sufficient. This has been proven over and over again in test-environments.
And if all deserts would be green again, covered in forest, earth temperature would go down a bit and then stabilise. Because the sunlight is absorbed by the trees and turned into wood and leafs, so it is used-up, and can no longer heat the surface. Wood is stored solar energy.
And if the whole earth would be green again, with 6...7x more plants than now, there is enough food for everyone, and for all animals. This would be very benificial too, obviously.
The chemical formula is: CO2 + H2O + lots of sunlight-energy ---> long C-H-O chains (=wood + leafs + juices) + O2.
In words: carbondioxide and water are turned into wood, leafs, and juices, if there is enough sunlight as energy source. And oxygen is released.
This O2 is the oxygen we need to breath. So we do exactly the opposite as plants: we eat green (vegetables, fruits, wheat, nuts,...; thus we eat stored solar energy) and we breathe oxygen in. Out of these we produce energy to move and to keep our body on temperature. And we exhaust CO2 and H2O. So, solar energy is first stored in plants, and then we eat these plants to release that solar energy in our body. We are running on "indirect solar energy".
Any process that consumes oil, or gass, and that produces CO2, greatly helps the growth of trees and plants. CO2 is the most important life-gas on earth, without which no life would be possible. So, don't feel bad when you need to burn oil, gas or plastic. As long as you burn it cleanly, without producing too much sooth and particles. You are greening the planet and improving life.
Long ago, the whole earth was covered in green. But bit by bit, the leafs felt on the ground, and all this carbon got entrapped underground, in the form of coal, brown coal, oil and gas. So it could no longer be part of the life cycle. Today there is not enough carbon in the life-cycle anymore, on the earth surface, so life is dying. We should dig up all this entrapped carbon (coal, oil, gas,...), and burn it so it can be part of the life-cycle again. And so that we can make the whole earth green again.
We need to produce way more CO2 than we do now, to save plant life.
Yes, I know that my vision is not "politically correct", but it is definitely and absolutely scientifically correct. Life is dying because of lack of CO2: there is only 0.03 to 0.04%. Below 0.02%, plant growth is no longer possible. We are at the lower edge: plants are in continuous CO2-hunger, and we need to dramatically increase CO2 output to survive. You can easily search for, and verify these things. This is basic high-school science. And you can verify it in every greenhouse.
So, clearly, plastic is a very good product, even if not perfect. As long as you don't throw it in the environment or in the sea. But you should or recycle it, or cleanly burn it to regain its energy.
Don't feel bad for using plastic, and for burning gas and oil. Don't feel bad for improving plant life and saving the earth.
