  • No one answered so I will:

    Have an enclosed printer! You won’t be able to print anything larger than a couple of cm otherwise. Also make sure to not have air gaps, any cold air getting in can potentially lift up a corner.

    You need a good first layer, even more so than with PLA. Have it squish a little more so that it sticks to the build plate like crazy.

    Preheat your chamber passively with the bed. With my enclosed Ender 3 I did 10 minutes before large prints.

    High bed temps: you might get away with 90°C at the lowest but 100°C is recommended.

    When a print starts to lift off the build plate there’s no fixing it. Either you’re fine with the warp (and some squished layers/deformation) or you have to restart the print. No way to sugar-coat this.

    Turn down part cooling as much as your overhangs allow, though with a hot enough chamber you might get away with “a lot” of cooling.

    Print with brim or adhesion tabs! Mind the geometry of your part: models with tall walls will tend to warp more.

    Tl;dr: printing ABS can be cruel, but it rewards you with strong, light parts that stay in shape even at high ambient temps like a car interior.



















  • Their high speed train network is impressive, but none of it was new technology when they built it. The first train sets they bought were Siemens Velaro D, a mature high speed train system that has been around in Europe for almost a decade prior.

    It ISN’T cost effective, but in China that doesn’t matter: what the state wants the state gets. No matter the cost. And I’m willing to bet that in 10 years time a lot of the stuff just doesn’t work anymore, line speeds get reduced and stops cancelled due to infrastructure not being maintained.

    We have seen chinese prestige projects fall into disrepair time and again, and their extensive transport network will see the same fate.
