Still waiting for the heater bed parts to arrive but wanted to test Kisslicer and a bit of speed and the LFS elephant seemed perfect. The material is ABS at a temp of 235ºc and layer height of 0.3mm to save time. Speed wise it was set at 55mm/s loops, 60mm/s solid and 75mm/s sparse, with 1500mm/s^2 aceleration. Bit of sagged filament around the legs but otherwise worked ok. There is a split in the back also but no heated bed and a cold room doesn’t help a model with only 10% infill.

Quesion is though I am amazed how well the model stuck to the masking tape even with a cold bed. So amazed in fact that it was near impossible to remove. The UP printers always print a raft so easy to get off just using a scarp scraper. What is the trick in removing your models unscathed when printing directly to the bed?
Nice work. Looking forward to seeing your output once the full kit is together. Waiting on my tax return to order the parts for my delta (my own unique design that is in the delta family). Your work is an excellent example of what is motivating me (which is the only reason I’m mentioning my future printer in your thread).
I been using painters tape and wiping it with acetone. Parts stick way good but sometimes the tape lifts. So then it’s off to retape the bed. I been playing with low infill (20%). It increased my time a tad bit.
I was gifted this elephant! Maybe not in that colour. It rocks. I believe the trick was to lay down some throw-away plastic using a spatula/paper towel that can be rubbed off once the plastic dried. Else, maybe grease?
I have a glass bed heated to 90 Celsius, I’m having luck printing directly on the bed - no tape, no glue. I have to let it cool to near room temperature and just pick the object off the glass. For the rare case where it stuck I use a paint scraper carefully around the edges, working towards the centre.
Thanks for all the great advice guys. I have a piece of glass to go on the heated bed so sounds like this wil help alot. . Also seems I need to get the get the enclosure built as a matter or urgency. It will be a combination of thin sheet metal (painted) and perspex I think.
@Zane_Mitchell There is a small deformation right in the centre, but the rest is perfectly smooth. I wipe it with a wet cloth, then dry off before printing. I also clean the extruder nozzle with a small wire brush before every print. If I am printing something tall and thin, I print two of them so the extruder is forced to leave one to dry while it prints the other. Otherwise it tends to fall apart as it nears the top.
