Obviously these are unsupported corners, so I have tried all types of supports, auto and manual. The results above are the best I could get, and still not what I would like. I achieved these results with these manual supports:
Note I have tried three different spools of BBL ABS and ASA, but the defects are the same. One of my tricks in the past is to use a raft, but that ends in disaster, especially when I used a very fine layer height.
I tried slowing all the speed and acceleration parameters down to a ridiculous extent but again the result is still horrible.
I do my designs in Onshape, so if you want to have a go a printing the part, here is the link : Onshape
What can be done to reduce the issue? It is possible for me to change the design within reason, but don’t really want to. I would prefer to change the printer parameters for a better result.
Fillets that start on the bed always look bad, at least me too. Try using a chamfer at the bottom then add a fillet to top edge of the chamfer so that it has one square corner that you could wet sand round after printing. Like this
That’s a very sneaky idea you gave me. Many thanks…
One other idea I have; and I’ve never tried this, so shoot me down if you think it’s stupid, is to make some ABS paint, by diluting ABS waste in acetone. I think I would need to experiment quite a bit though…
Hello, I am also fairly new to printing with ABS and have had good results. I have downloaded a copy of your component and have made some small alterations. I will test print this tonight on my P1S and provide you some valuable feedback soon(hopefully).
Hello wellco. I have essentially reduced your edge fillets by half and changed the print position. I have also removed your screw holes for simplicity. I had good results printing with Bambu ABS.
I can’t figure out how to attach images to this forum post. Perhaps someone can assist me?
I’m afraid the forum is still not allowing me to add any images. I keep getting “An error occurred: Sorry, you can’t embed media items in a post.” I wonder if it’s because I’m so new to the forum?
I’m having the same issue (using PLA), it’s driving me crazy.
The thing that gets me is that I printed a side spool holder:
and when I see other people pics the bottom end/overhang came out super nice but no one has put if they used different settings. I slowed it down, changed filament, used adaptive and used supports. What are we missing here with this issue if for other people it comes out fine?
I realise what it’s doing and why it is needed, but it doesn’t have to be done in a childish and patronising way. AGAIN “as it seems to me”. You may not think this, but I do.
I think it’s the larger fillet there coming up right from the first layer on the bed. Can you place the side where your hand is on the bed to print? Bed placement is a key component to a successful print!
