Topic: problems with large print

Hello Soildforum

I am running into some problems printing the part pictured below. This is about a 62 hour print. I have had my Solidoodle 3 for about a year now and am still tuning the printer. I normally print part in the 20 to 30 hour range with descent results. I would just like to ask Solidoodle user if I am asking too much of this printer and if not some options to try to improve my print quality. I am attaching two picture below of the part when it when south about 10 hour into the print. I have my bed level, extruder calibrated and setting that have worked for me in the past. I am using Simplify 3D to slice and export my Gcode file. I have not used slicer3 for slice and exporting Gcode as it normally would not slice 90% of my model. I am printing the model with the extruder tempter set at 213 and the bed set to 105. I was also using 8mm brim around the part. As you can see in the print it is getting a lot of excess plastic oozing on the ID of the part. As you can see the OD looks descent with a small amount of banding. I hope I have given you enough information to help me with this problem. Please let me know if you need more information.  Thanks

Re: problems with large print

Welcome!

Looks like a toughie! Good work with the 30h prints, that is an achievement already. Based on that and the glass in the photos we can safely assume you're not at all new to adhesion, enclosures, temperatures, etc.

What's the exact problem preventing the print from continuing - is it the warping and subsequent nozzle crashes? I can't see quite what you mean by "oozing on the ID". There are some lost threads, but I'm assuming they're from after the print has failed already.

I don't know anything about simplify3D but those supports look too thin to me.  Is it failing because the supports fall over?  It looks like it might even be able to print that without supports, overhangs don't look too bad.  Will it run thru slic3r if you put it thru netfab first?  I recently started using rectilinear grid supports and I like it a lot better than pillars.  Just my 2 cents.

+1. Based on the screenshot, it looks like you designed these in yourself, or did you use the Simplify3D tool? The reason I ask is because the supports appear before slicing... but I'd agree, will it print without support? That will cut down time, which will leave the print less time to warp.

Re: problems with large print

what is your layer height on this print? Looks like .1mm which imo seems to be overkill for this print.

Do you have your printer enclosed?
