Messed up Print - Looks fine on Cura 3.6.0 - But print ISNT

[Rifraf66 1]

Hi

 

I have printed out a candle stick - which is created in Autocad 19 - looks fine in Autocad. I create an STL file and import into Cura 3.6.0 - again looks fine. But when it prints - what is on the screen in ACAD/CURA doesnt print out right. See screenshots below. Can anyone help?

Always look at your part in layer view before printing.  You looked at it in solid view.  Please show a screen shot of layer view and use the color scheme as "line type" so I can get a feel for the issue.  

 

I'm guessing there is something wrong with the model though - you could try sending it through the netfabb repair service.

netfabb free repair service is here (you have to create a free acocunt first):

...or is it printed with enabled support and what we see is the support material that is (for some reason) more fused with the object then intended?

HI Guys

 

Thanks for your input. It does indeed appear to be the support material - because when i break it into 2 pieces  - the actual candelstick i modelled is inside - but i cannot remove all the support material that has been fused onto it.

 

When i remove the create support prior to slicing - it prints out fine.

 

Jeez - i tried it 4 times before i saw your comment and unticked the "support" box on Cura.

 

GR5- netfabb sounds like a great resource to have access to - many thanks for the link.

 

Thank again.

You can play with lots of support settings.  For example XY distance will keep the support from touching the sides of your model.  And you can play with the overhang angle.  Or you can just create your own support in CAD (that's what I often do).

By the way, the main reason I asked you to post a screen shot in layer view was because that shows support in a different color and I also suspect it might be support except... it just didn't look like a typical support pattern.

Hi GR5

 

Yes your right - i looked and it showed the support as you said. But i do agree -  best put some supports in cad - especially for those canitlever bits where there is nothing underneath. I should have added something thin in CAD that i could easily remove after it's printed.

 

My CAD skills are poor as i normally have a cad guy at work to drawing work for me. I am using a 30 day trial version of ACAD that i am playing around with at home. Took me about 10 hours to do that candle thing - thats how poor my cad skills are.

 

Many thanks again - am learning slowly.
