Hi, I recently read the thread about THF not working to smooth PLA surfaces, so I started looking in to HIPS and Limonene again. From the few videos its established that it can be completely dissolved as a support material but is there some mentioning out there of Limonene used to smooth out HIPS surfaces? From what I can tell about the process its not hydrolysis so the material doesnt get brittle and starts to crumble but rather melts away like acetone on ABS. Anyone ever try smoothing with Limonene and HIPS?

1 hour in and it HASsmoothed very nicely but still feels tacky.. i'm wondering if there is a way to harden it up/speed the process? UV/Hot/Cold/Airflow?]]> 88Zombies General Tue, 27 Mar 2018 07:49:53 -0400 https://reprap.org/forum/read.php?1,478682,478682#msg-478682 https://reprap.org/forum/read.php?1,478682,478682#msg-478682
