I am trying printing a architecture with pitched roofs. But the top of the pitched roofs is not satisfied, since it is very thin. During printing , the nozzle is very close to the model. So it is melt by the nozzle and move with the nozzle together. Btw, now I am using 0.4mm nozzle. Is it possible to make a good result for the pitched roofs with a smaller nozzle such as 0.2mm? I enclose a picture of a similar dome to the one that I’m trying to print.

Thanks a lot!

I think you have to slow down the print near the top, and add some minimum time between the layers.

Keep your fan(s) up 100 percent, and give each layer enough time to cool down.

One thing to do in this situation is to print a small pillar some distance away from the printing model. Pillar should have same height as the printing model. By this the nozzle will move back and forth between model and the pillar so there will be adequate time to cool down the layers.

try printing the roof with one or two dummy pillars next to it. That will give the layers time to cool off before the next layer is deposited. Works for me!

What software are you using? You need to increase the minimum layer time to allow some cooling.

Incidentally one of the very first prints I did after buying Simplify 3D would have had this issue, but I was blown away by the job it did right out of the box. Check out the pics. Not saying it can’t be done in other software though…

Hello,
I did similar work but with the Project 360 in chalk dust. The model has a diameter of 50 mm. about (I am attaching photos). But long ago I did it with the ABS and came pretty well. The diametrro dell’uggello is fine to 0.4, you probably need to set the best 3d printing values.
There, hello good job.

advice, seperate the top of the design and slice it in two parts and print those horizontaly. Glue them together and way you go!
