Newbie user requires help with print issues

Hi…I’m new to 3d printing, and recently purchased an SV06 plus to use with my model stock car making. I designed some 1/64 scale body shells in Tinker Cad ( really basic design platform that they use in schools etc) and created some reasonable prototypes in PLA, however they were a bit fragile, as expected. I followed conventional wisdom and reprinted in ABS ( for strength) but the results looked pretty ropey, especially on the edges of the roofs) Next suggestion was PLA plus (I’m told it’s stronger?) but the roof edges were even worse ( please see attached pic) Just wondered if you had any suggestions…perhaps I need to print the roofs separately and then glue them on? Many thanks in advance!

Hi,
Could you give us you print settings for eachenfilament ? (Speed, temperature, retraction, …)

Most likely you need to use supports.

Wall thickness: 1.2 mm Wall line count:3 Print temp:200 plate temp :60 Speed :150mm/s
Cheers Lion, I was beginning to wonder if that was the case.
