Print a 215 x 215 x 200 mm cube on the UM3 as advertized in the specs (real build volume)

Recommended Posts

Hi anyone,

If I print (with only one extruder) from Cura, how can I get this 215 x 215 x 200 mm cube advertised on the UM3 specs ?

Even with any adhesion methods turned off, the cube only turns yellow until it's scaled down to 83%

May sound stupido but how could I print according to the largest build envelop ?

Because of things like extruder prime locations, and the extruder switch bay protruding into the build volume, there are areas along the depth of the machine where you can't reach the full width and areas along the width of the machine where you can't reach the full height. These areas are shown as grey shadows on the buildplate.

If you turn off build plate adhesion options, it should be possible to print a block of - say - 10 wide and ~20.5 cm deep centered in the buildplate. A full block on the buildplate is just an unrealistic "worst case scenario".

Can't be done. Period.

No Ultimaker printer yet has been able to print an object the size of the advertised build volume. Simply stated, they mislead about it in their sales literature, to be kind.

And don't forget about the horrid build-plate clips that also preclude use of parts of the area.

...so... we can print 215x215x200 (or 300), just not all at the same time, or all of the time?  ie.some shapes can reach 215 wide in some areas of the build plate... same for other dimensions?

Correct regarding X and Y directions. I haven't tested the Z-height - that would vary a bit based on the print-head and nozzle used.

BTW, your actual Ultimaker may or may not work with those last few end-of-travel millimeters at the right.

Depending on the exact location and bend in the Home limit switches, you may lose a millimeter or two when you try to print - mine can actually print a 220mm wide object between the clips.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
