I’m using an Ultimaker 2, so 3 sides are closed. Open on the top and on one side. I tried with heated bed up to 110°C. The part is still curving on the bottom and the wall aren’t straight, specially on the bottom. That means it’s too hot on the bottom right? Do you think another position will give better results (higher contact surface with the heated bed)?
Two pictures are attached.
Sorry, not sure I can share the part because I’m printing it for a customer.
I also use an U2. Never got ABS to print properly…If it warps at the bottom, try a sheet of buildtak on the plate. I haven’t used it with ABS, but on the Makerbot with PLA its fantastic. Much much much better than blue tape or hairspray!
A second part which look quite the same does always loose from the bed, and always at about 90% of printing
Each test takes 9 hours, it’s quite difficult to understand what happens. The walls are straight by 100°C. I tried with 110°C and the wall are not straight on the bottom.
You HAVE to use kapton tape You HAVE to degrease the kapton tape You HAVE to make a front cover on your um2. You HAVE to heat the bed to 110-115 deg. You HAVE to use rafts to lift the model from the heat to prevent elephant foot print. I have made 100hours abs print this way, and always have success.
I was having terrible problems with my ABS prints. I read everywhere that fan should always be off. I tried your suggestion and it made a huge difference! Thanks.
