Hi all, One of the measures that Material Extrusion systems beat Photopolymer systems is handling of the excess, waste, reject, and raw material. There are services available to collect and recycle unwanted PLA, PETG, etc. As far as I am aware waste from photocured resin systems is landfill when fully cured and hazardous in its raw form. I would like to have a go with using a support material, but I am concerned about how the waste product is handled. With Disolvable supports it seems that the waste is classed as chemical waste and there is no one looking into recivering the dissolved material and making it re-usable. Have I missed something? https://reprap.org/forum/read.php?425,860514,860514#msg-860514 Fri, 04 Sep 2026 18:40:51 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?425,860514,860668#msg-860668 https://reprap.org/forum/read.php?425,860514,860668#msg-860668 WesBrooks green talk Fri, 11 Oct 2019 17:40:27 -0400 https://reprap.org/forum/read.php?425,860514,860663#msg-860663 https://reprap.org/forum/read.php?425,860514,860663#msg-860663 VDX green talk Fri, 11 Oct 2019 15:27:00 -0400 https://reprap.org/forum/read.php?425,860514,860647#msg-860647 https://reprap.org/forum/read.php?425,860514,860647#msg-860647 WesBrooks green talk Fri, 11 Oct 2019 09:52:47 -0400 https://reprap.org/forum/read.php?425,860514,860611#msg-860611 https://reprap.org/forum/read.php?425,860514,860611#msg-860611 VDX green talk Thu, 10 Oct 2019 18:15:53 -0400 https://reprap.org/forum/read.php?425,860514,860563#msg-860563 https://reprap.org/forum/read.php?425,860514,860563#msg-860563 WesBrooks green talk Thu, 10 Oct 2019 02:42:32 -0400 https://reprap.org/forum/read.php?425,860514,860561#msg-860561 https://reprap.org/forum/read.php?425,860514,860561#msg-860561
There would be significant and potentially toxic out gassing from that charcoaling process wouldn't there?]]> WesBrooks green talk Thu, 10 Oct 2019 02:34:36 -0400 https://reprap.org/forum/read.php?425,860514,860534#msg-860534 https://reprap.org/forum/read.php?425,860514,860534#msg-860534
One of the ideas in my project description for handling the catched "open-sea-waste" is to heat it in inert atmospere (autoclaved?), so it will be reduced to mainly charcoal -- this could be done here, on "mainland" with the collected plastic too ...]]> VDX green talk Wed, 09 Oct 2019 13:56:46 -0400 https://reprap.org/forum/read.php?425,860514,860514#msg-860514 https://reprap.org/forum/read.php?425,860514,860514#msg-860514
