I’ve never actually printed anything other than PLA, but... Searching the web for filament density, I found this article , among others, that indicate that PLA is nearly 20 % denser than ABS, on average (1.24 vs 1.04 g/cm3). This indicates that a 1 kg reel of ABS will have 20 % more volume (therefore length) than a 1 kg reel of PLA. This does not quite ...

The up-curling of overhangs is frequently seen when printing PLA or PETG when the just deposited layer hasn't been cooled enough. The residual heat will allow the curling as the plastic has not been fully set (above the so called glass temperature) because of insufficient part cooling. Knowing that ABS doesn't need much cooling (to improve the inter-layer ...

In my experience, polyurethane sticks to PLA like super glue, not good. But silicone and alginate doesn't stick at all. What I do is print the model of the mold with PLA or ABS, no matter. Then, cast a mold of the PLA model of the mold with alginate, then you have the negative of your mold. Now with this alginate mold of the mold cast your actual mold with ...

You should do a complete calibration for ABS (temperature tower, E steps, flowrate %) before starting the print, then when you change filament remember to apply all the parameters I mentioned. While I'm not in favour of using the flow rate % to correct the E steps calibration, since you are doing it mid print this may be the easiest way, instead of changing ...

You could CAD a 1 layer thick cylinder, and add it to your print and place it around your object. You can create any number of cylindrical shells that way...

Actually, Both PLA and ABS could use for structural parts. PLA has high strength and is brittleness. ABS has better thermal resistance and durable. PLA and ABS are the main types of 3D printing material, each has cons and pros. If you want to choose which type, you need to know the detailed application.

ABS can be a problem to print, but there are generally a couple well established methods to prepare your glass bed, which might be combined for best results: Heated bed. A heated bed is almost a must for ABS and would be set to about 75 to 90 °C for most printers. Often this can suffice on its own, but keep the bed running for the whole print! ABS-Slurry. ...

Yes I had this same problem myself. You will need to re-insulate it using a silicone block and next time don't leave the window open while printing. Just keep the fan or AC on to circulate the air.

Results of the suggestions in comments and answers Following are the results, coming from the great answers received on this page. I post them here in case it can helps further readers in achieving good results. Note: when two numbers are indicated, the first is for the first layer, and the second for the rest of the piece. (e.g. 250 ºC / 230 ºC) If you ...
