I fell in love with textured abstract art after seeing it on Pinterest, but it never occurred to me until recently that I could achieve the same look without the hefty price tag of buying original textured art. It can take a while – years even – to find art that speaks to you. If ou want to scale in Cura, just scale all parts equally.Art is an odd thing. So just cut it apart in your modeling software (maybe add some tabs and holes to make precise and stronger assembly easier) and import them to Cura one at time. Cura doesn't rescale your models unless you tell it to. Lower print temperature and higher travel speeds (also Cura settings), will also reduce stringing.Ībout the splitting objects question. Enable retraction, and start with something like 40 mm/s speed, 4 mm. It can be reduced by tweaking the 'Retraction' settings in Cura.

This is a result of print material leaking from the nozzle while the print head is traveling to a new destination. Just a thought.Ībout the stringing (which is what the 'stringy messy stuff' is called.): PLA is a much easier material to work with, it prints cooler than ABS, shrinks less, and you will likely have no issues with that, even without a heated chamber. Is there any particular reason you are printing this in ABS in the first place? (Do a search for Ultimaker heated chamber). Its hard to enclose the top of the printer, due to the bowden setup, but it has been done. Given some time, your heatbed will heat up the air inside the printer, and this 'oven effect' will help keep the ABS from shrinking, and thus help prevent your print from cracking. Adding something in the holes, and top (like acrylic plates or similar), to keep heat from escaping the build chamber. The best ABS prints are achieved by closing off the printer. I don't think your problem with the cracks is an underextrusion problem, but rather a classic result of the ABS material shrinking when cooling down, which tears the layers apart. Thank you for your time and Happy New Year! We also manually split the model into two obj files but is there a way to match the size perfectly? Any solution to make them the right size? We tried to separate a tall model into parts by using the 'split into parts' but the scale is different, so it would be right when I put the two together. This is when I continued to print with reduced speed.Īny idea why this is happening? Is it a under extrusion problem?Īlso, is there any way I can avoid the messy stringy stuff? I looked up on line on the forums and tried speeding it down to 70-80 and below is the temperature setting. The crack was so severe that the print actually broke in half. I recently purchased ultimaker original + and printing with ABS filament and getting serious cracks between the layers.
