UM in cold room -> warping and other unpleasantnesses

Posted (edited) · UM in cold room -> warping and other unpleasantnesses

I have no other option but to place my Ultimaker S5 in an unheated basement room. This was fine until the room temperature dropped to 10°C (or less), and now it is becoming impossible to get good prints. Breakaway and PLA tend to warp horribly, and I presume that this is because of the huge temperature gradient: the newly added layers cool down too quickly and contract, whereas the lower layers are kept warm by the heated bed plate.

 

How can I remedy to this situation? As I said, moving the printer is not an option. Heating the whole room is impractical and too expensive. I was thinking of adding a cover (https://accante.com/en/) but I fear that this is not going to be enough. Are there any add-ons that would allow to keep a well-controlled air temperature within the printing chamber?

    Hmm, you need definitely an external heater to bring the printer environment to 20-25°. So the cover you have linked will not work, it will be better but not enough.

     

    Do you have the possibility to build a small print room within this basement and put a small heater inside, just to heat this area? I don't know the word in Englisch, but I mean to use these plaster panels (hope you know what I mean)

     

    Or if not possible to build a bigger box of wood, but not just for the printer, higher that you can put a small table inside and a small heater.

     

    Another idea, but just an idea, not sure if it really works, if you put a radiant heater beside the printer, which should just heat up the area around the printer and only during printing. They are normally quite fast with their ventilation.

    I had the same problem with another printer in the past, closing the printer made it impossible to print with pla (no more cooling), so i gues that if you close your printer, you also have to "regulate" the temperature otherwise it will become to warm.

    I thought that I might attach something like this to the cover: https://www.aliexpress.com/item/Black-NEW-100W-12V-DC-PTC-Fan-Heater-Constant-Temperature-Incubator-Hot-Space-Thermostat/32839650955.html

     

    It would still need some kind of thermostat though. It's going to be a rather involved modification, I fear.

    sorry, now corrected.

    100W 12 is at least 8amp power supply.

    Once you close the printer, the problem will not be to cold, but to warm i think.

    If I understand correctly how these thermistors work, the surface temperature is constant, and the heating power will depend on the dissipation (=airflow), which in turn can be controlled by replacing the (probably horrible and loud) included fan with a nice Pabst high-quality voltage-controlled fan.

    i would turn the fan on, and switch the heater with a thermostat.

    I think I will use a thermostat like this one: https://www.aliexpress.com/item/12V-High-Precision-Thermostat-Digital-Dual-Relay-Alarm-Thermometer-Temperature-Controller-Air-Regulator/32842614345.html

     

    It has two relays, which in principle would allow to control both the fan and the heater.

    Just one remark, make it safe!!you don't want these things to fail, risks are high. Get at least on the heater circuit a safety thermostat, if this aliexpress thing fails, and you are not around (prints can take a long time), you don't want the thing to overheat.

    I have a similar problem in a room above the garage with no heating. I bought an oil filled radiator four years ago which does the job for me. it probably runs on no.2 out of 6 or so and keeps a constant temp of 20-22 at that level, at a cost that we do not notice

    What if you put a piece of plastic or cardboard in the front opening, like a sort of primitive door, but with a few holes in it? So there is some circulation to evacuate the heat, but not too much?

     

    At least, cardboard is cheap, so it could be a good test to see if this really is the cause, and not something else that happened to occur at the same moment (e.g. dirty, oily glass).

      • Here it is. The new UltiMaker S7
        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.

      • UltiMaker Cura 5.3.0-Alpha 🎄 Tree Support Spotlight 🎄
        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.
