I have used my Mendel90 printer with .4mm and .6mm nozzles and there is a lot of difference in the print time and quality. I thought some time ago that it could work to have 2 extruders which instead of having different colours as is usual had different nozzle size so that the main body could be printed at low resolution and the outside with a fine nozzle. I didn't follow up my thoughts in the area being too busy with other things but a friend recently referred me to a commerial printer using that idea. [robox.cel-uk.com] I was wondering if anyone had implemented this on a reprap open source design? https://reprap.org/forum/read.php?1,353890,353890#msg-353890 Thu, 08 Oct 2026 03:02:23 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,353890,355669#msg-355669 https://reprap.org/forum/read.php?1,353890,355669#msg-355669 diytechshop General Thu, 15 May 2014 15:06:07 -0400 https://reprap.org/forum/read.php?1,353890,354732#msg-354732 https://reprap.org/forum/read.php?1,353890,354732#msg-354732 Srek General Tue, 13 May 2014 15:57:22 -0400 https://reprap.org/forum/read.php?1,353890,353890#msg-353890 https://reprap.org/forum/read.php?1,353890,353890#msg-353890 I thought some time ago that it could work to have 2 extruders which instead of having different colours as is usual had different nozzle size so that the main body could be printed at low resolution and the outside with a fine nozzle.
