It is not possible to print at maximun vuild volume

[frangomez 0]

Hello,

I am trying to produce parts sized 202,5x203,7x20mm. But when I opened it in Cura, I only can print it without skirt and without brim.

The maximun build dimension for an Ultimaker 2 is 223x223x305mm. but the reality is far from that. The reality looks 20mm shorter.

Do you have experience printing at "maximun build volume"?

do you have a solution for this issue?

Thanks in advance.

What you say is true but it's more complicated. Mostly you have to worry about the clips.

If you know 100% certainty that the nozzle won't be hitting the clips then there might be a way to print to that full volume.

Yes, I have care about the clips. But I need to know the real maximun square part that I can print in one Ultimaker 2 or extended.

Just now we are printing parts for tile makers and the standard size is 200x200mm. plus walls we are in 204x204 or close to that.

Please tell me the way to can print to full volume.

regards

A brim and skirt add additional lines which are wider than the part you are trying to print.

A skirt could be handy but if you print a part as big as the entire plate you don't really need a brim. A brim is used to increase adhesion to the bed for smaller prints, which obviously isn't the case with your print.

Taking the clips in mind I can make it into 220-205mm so this '202,5x203,7x20mm' should fit.

Good luck!

Well you can design a kind of raft until you are above the clips and then print the full volume from there up.

Hi guys,

I've got a Ultimaker 2 Extended+ which states '223 × 223 × 305 mm' build size. Just as discussed I cant get anywhere near that build volume. Current print is about 204 x 206 x 202 and says its to big. I've checked I've selected the right machine.

You mention a raft, how far away from the edge would you have to make it to avoid the clips?

Think its odd to state such a big print size when its clearly not that simple.

Cheers in advance

Yes. They give out a build volume but it's more complicated because you have to avoid the clips as you say.

Also if you use brim or skirt (you can set these to zero but I would do at least one brim pass if it fits) you might violate the build volume for that also.

By the way those supports are much too thin. Some people use the 10% rule but I use the 20% rule - posts should be at least 20% as wide as tall. They can taper as they go up as long as you stick to that rule.

Those posts will wobble too much and get hit by the print head and *might* fall over.

Would you consider cutting this part at an angle half way up and flip it over and gluing it together after printing such that the "join" is touching the bed for both halves? If you do that then you don't need any support. Plus it will probably fit diagonally letting you have lots of brim. Or maybe "CAD split" your model such that one slides under the other with 2cm of overlap for a strong glued joint.

Cheers for the advice and heads up on the 20% supports rule, I'll try splitting the model as you say and see how it goes. Thanks again!

You will also find that there is some missing print volume because there is no second extruder, which would be needed to get close to the right edge.
