Help in printing stairs

Recommended Posts

I am trying to print a floor plan of a building I designed, I have a somewhat circular stair going up a central wall and enclosed within 3 walls. I drew all the steps and risers going up to the next floor. The spaces under the stairs are empty.

The first time I tried printing the plan I got only the steps (no risers) and they were stringy and not solid at all (I did not specify supports).

The second time I printed only the stairs and the central wall and enclosed them within 3 walls (under the outer edge of the steps and risers) and with supports, same problem, no risers and stringy steps.

Can someone please advise how stairs should be created for 3d printing, if hollow underneath or solid?

I'm using PLA and temperature is 210, pics and parameters are posted. Thanks for any help.

You need to include a picture of the basic page.

If you remove the floor section under the stairs the the infill will support them. It also looks like you need to increase the top/bottom thickness. 6-8 times the layer height.

Hi labern, The top and bottom thickness are .8 The fans are on 100%

It looks like you may be right about the T/B thickness, I am doing another print with a thickness of 1.2mm and the quality is a lot better, but I didn't add the stair (unfortunately). I will print that later and if it comes out ok I'll just drop it into place.

Old vs New huge improvement...
