6th day printing problem - help needed

I'm in the 6th day of printing this fishing pole carrier. I went to my basement to check progress a little while ago and noticed that all of the supports under the middle of the handle had broken off and were laying sideways, and the printer was making a mess where the supports should be. I have the print paused. Any suggestion on how to fix or proceed is greatly appreciated.

Thanks

The print, as a single part, is unrecoverable.

Remove it and clean it up - it might be possible to cut the part horizontally(tool pane at left of slicer), print the missing upper section, and join them somehow.

This is an ambitious print for a new user...

Where did you get the file?  It doesn't look like a well thought out printing design.  If you have access to the source file I suggest you seperate the handle so it can be printed laying on the bed to gain some strength from the lay of the filament and then fit it post printing.

Cheerio,

Thanks. I downloaded the print off Thingiverse and saw that someone had uploaded a successful print, as well as a remake. I'm bummed about the wasted time and filament, which was my biggest fear before starting a days-long print. I tried the same print once before and only got through a few hours before the print separated from the bed. I thought I had solved my problems by turning on supports & adding a few mouse ears. Oh well.

Warp monster plated like that.  Stand it up on end.

lesson learned I guess. Any suggestion on how to tell which .stl's are not going to print well? What to look out for?

@dan-rogers

Absolutely. Printing it standing up is the logical orientation. 

@boslaw

The orientation of a model in an STL file is not always the best for printing. Which is why I like 3MF projects because--at least in theory--the author should have oriented the model optimally. In general, I would try to find an orientation that minimizes support. (Assuming no need to worry about forces applied to the model in certain directions, which may influence the choice of direction). 

Which models are not going to print well? Too long a list, really... But some signals for possible issues are thin walls, tall and thin models, lots of overhangs, long unsupported areas that may require bridging, small contact points with the print bed, large flat models with sharp corners that tend to warp, and of course models that have not been checked for errors, which is unfortunately a large portion of models on archives such as Thingiverse.

A lot of models on thingiverse have never been printed by the authors - you can usually tell a "student assignment" because not one of the pictures will include an actual print.  I approach those cautiously.  The ones that are labeled school assigment, etc, just move on.

and not just on Thingiverse.

For any model, if there is no print pictured, assume trouble.  For any functional part, if there is no picture of the part in use, assume trouble.

You are printing fishing gear: if the picture includes a decent fish then there is at least a chance you are not wasting filament.

Get the idea?

Cheerio,

Very true!

In all fairness to the designer though, this seems to be a fishing rod carrier, not a rod itself. Of course nobody in their right mind should even dream about printing a fishing rod with FDM technology unless you want to tell your grandchildren about the One that Got Away because of a broken rod...

Parenthetically, I would suggest using a material such a PETG to print this carrier as it will be exposed to water and the weather. I don't think you'd have a lot of joy with PLA.

Whereas I have been testing and refining the design of a series of fishing reels over the last three years; they are getting good enough that on many trips they are the only reels I take and I'm getting plenty of fish.  They will be ready to publish later this year I hope.

I would suggest using a material such a PETG to print this carrier as it will be exposed to water and the weather. I don't think you'd have a lot of joy with PLA.

Neither water nor weather have as much effect on PLA as some fear - 'though sunlight/UV does degrade pale filaments quickly.  I too would use PETG but in my case it's because I would expect the part to be subject to rough usage and PLA is likely to shatter whilst PETG is much tougher (not as strong but more resilient to shock).

@Boslaw,

 

Your problem piqued my interest a little so after a brief search I found the STL on Thingiverse and sliced in in PrusaSlicer for my machine.  I am currently setup with a 0.6mm nozzle and the supports (painted on) probably need tweaking.  With the model oriented vertically and supporting only the areas that I think are troublesome, the print time is 12 hr 21 minutes.  I have attached a zipped .3mf if you would like to look at my settings, etc.

 

Regards,

Steve

Thanks for this. 12 hours is a big difference from 6 Days! I'm an extreme noob so I'm still learning about what all of the various settings are for.

@Boslaw,

You are welcome.  I am not much beyond "noob" myself but I've learned a lot reading here on the forums.  Be cautious using my settings directly as I may have used something in my setup that is not compatible with your printing settup (the 0.6mm nozzle for instance).  If you have any questions about things you see please feel free to ask.  I will add that after I sliced the model for my 0.6mm nozzle (the .3mf I sent) I went back and sliced it again with a 0.4 mm nozzle at 0.2mm layer height and got a 1 day-ish print estimate.  Changing nothing else, I selected a 0.3mm "draft" layer height and the calculation dropped to about 13 hours! 

Regards,

Steve
