Evolution of my extruder Hi everybody. After many weeks i have finally build extruder which i wanted from start. Its cheap, can be simply dissassembled, nozle replaced with different diameter, or when i change material, fits fine on my mendel and printing results are clean. (right now im using 0,35mm nozzle) (Takes 6 variations to get this one :0)) ZemcikO_hotend_v_2_3.jpg mod_embed_images_loadimage('1d46839271412fe1a554880f54fb22c4', '/forum/thumbcache/55f/a80/fe7/d2b/2de/ce2/11c/f54/878/cb6/67_800x400.png', 'http://www.reprap.org/mediawiki/images/1/1b/ZemcikO_hotend_v_2_3.jpg', 'https://reprap.org/forum/addon.php?70,module=embed_images,check_scaling=1,url=http%3A%2F%2Fwww.reprap.org%2Fmediawiki%2Fimages%2F1%2F1b%2FZemcikO_hotend_v_2_3.jpg', '', 92684, 800, 400, 'Loading image ...', false); And of course i wanna share my results and 3d/2d drawings with comunity, so here it is: my reprap page Another positive thing is, that u do not need expensive peek.

Rebuilded heater element.
1. 2x heater resistor 6R8 instead 1 piece (warm up 4x faster and temperature is more stable even with fan on)
2. bigger cooling copper ring + fan on printhead.
3. now it can be very simple and fast mounted and dismounted w/o risking electronic parts...

Version 2.3 works great on clasic type Mendel. V 2.4 is designed for "prusa" carriage.
Another improvement is mechanical clamp for resistor and thermistor and increased distance between printed piece and heater.
Double copper cooler (instead single cup) is recomemned.
Complete documentation (2D and 3D) is included.]]> oz Plastic Extruder Working Group Sat, 05 Nov 2011 10:57:27 -0400 https://reprap.org/forum/read.php?70,92684,92775#msg-92775 Re: Evolution of my extruder https://reprap.org/forum/read.php?70,92684,92775#msg-92775 Traumflug Plastic Extruder Working Group Wed, 03 Aug 2011 02:24:04 -0400 https://reprap.org/forum/read.php?70,92684,92684#msg-92684 Evolution of my extruder https://reprap.org/forum/read.php?70,92684,92684#msg-92684 After many weeks i have finally build extruder which i wanted from start.
