Best way to print this?

[fingerpuk 0]

Hello.

I can't figure out how to post images, so here is a link. I'm happy to share the model also.

I just wonder what the best way to print this would be, at about 120mm tall? Should I do it standing up, if so does it need any supports? Or lying down, with a support structure? I feel upright makes more sense, with some custom supports maybe around the bottom to support the weight?

Cheers.

As for the model. I'd print it as it stands in the picture but add a little bit of support to the pointy bit at the bottom. The three legs and the rest of it will likely print just fine as is. The only thing is that the rings/windows might have a wee bit too much overhang but it's hard to tell from the picture. If you can keep the angle relative to the ground plane at about 45 it wont have any problems at all. It can do more acute/steep (I suck at the correct terminology... but I think you know what I mean) as well but I find the bottom surface tend to be less than stellar.

I'd add a single column of support for that lower point on the body of the rocket using MeshMixer, and print the rest with a decently large brim.

Yes! What those 2 guys said! One support for pointy bottom in center, and use lots of brim - maybe 10 passes of brim. Make sure you use some glue stick on your glass bed and make sure you heat to 40C to 60C. I wouldn't go over 60C for this part as you want it to stick really well. Make sure the bottom most layer is squished well into the glass. If not it might fall over during printing. But if you use glue, bed temp 40c to 60c and squish the first layer, and brim - then this thing will not fall over even if your cat attacks it.

Cheers all. One question, where do you set the amount of brim layers? Just finished printing the test robot, came out not too shabby apart from it's deaf in one ear.

The brim setting is on the middle right under Expert -> Open expert settings

The right ear deformity is something pretty much every new user asks about and it's a cooling thing. The right fan doesn't quite reach on small prints. Printing two at the same time can help with this.

Ah, great thanks. I'll try that later.

Also make sure your bed is no hotter than 70C (the default is 75C which is too hot), and for the robot I would do 60C.

Make sure your fans are really working (the left one must be if the left ear came out okay).

Lower temp a little bit maybe to say 210C. And print slower - 30mm/sec. This will all make the robot come out better but also it will take longer so everything is a tradeoff. If you are happy with how it is now...

I'll give it a try later. If I combine all the tips I reckon I'll get a sterling print.
