Has anyone tried using FR-4 perfboard as a bed?

Posted · Has anyone tried using FR-4 perfboard as a bed?

Hi,

I was reviewing the Make: Ultimate Guide to 3D Printers and noted something novel in the Afinia H-Series. I'll quote

 

Also provided are a set of FR-4 perf boards for the print surface that offered surprisingly successful printing adhesion, and could be cleaned easily using the included tools to push plastic up through the holes

 

I was wondering if anyone has tried this with their Ultimaker? I'm constantly dealing with failed prints due to either poor adhesion (because I start the hotend too high) or ripped blue tape and hours of scraping PLA off the bed (because I start it too low) ... hence my interest in this option.

Choco.

    Hi Choco

    I don't think it would be flat enough.

    If you slice your part with an outline you can manually adjust your platform by twisting the coupling at the bottom of the leadscrew while it is printing the outline so the nozzle is just off the platform.

    FR-4 and its predecessor, G10, can be very flat. They are used in printed circuit boards (PCBs) and, yes, there are many heated beds that use a PCB with copper traces as the heating elements.

    Personally, I'd prefer not to have the hole pattern on the bottom skin of all my prints and would opt for a solid board. At one point, I considered using a thick piece of G10 instead of the MIC-6 tooling aluminum I'm now using. Aluminum conducts heat better (faster warm-up from my underlying silicone mat heater).

      • 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.
