I modified an extruder design that Matt Laberge had uploaded and printed it with my old extruder. The new extruder uses 1.75mm ABS plastic filament, so it is much easier to work with a melt down than 3mm. It is acuated by a geard NEMA 17 stepper motor and also has a spring loaded idler wheel to account for slight changes in filament diameter. I also am using a .35mm nozzle for higher resolution with a .25mm layer height. The old extruder used a .50mm nozzle with .50mm layer height so I have effectively doubled the resolution. The new extruder is also around a quarter the size of the old one.<\/p>\n<div id=\"attachment_340\" style=\"width: 610px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.grassrootsengineering.com\/blog\/wp-content\/uploads\/2011\/09\/greng_2001.jpg\" rel=\"lightbox[743]\"><img aria-describedby=\"caption-attachment-340\" decoding=\"async\" loading=\"lazy\" class=\"size-full wp-image-340\" title=\"New Extruder Being Printed by the Old one\" src=\"http:\/\/www.grassrootsengineering.com\/blog\/wp-content\/uploads\/2011\/09\/greng_2001.jpg\" alt=\"\" width=\"600\" height=\"450\" \/><\/a><p id=\"caption-attachment-340\" class=\"wp-caption-text\">New Extruder Being Printed by the Old one<\/p><\/div>\n<div id=\"attachment_340\" style=\"width: 610px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.grassrootsengineering.com\/blog\/wp-content\/uploads\/2011\/09\/greng_2002.jpg\" rel=\"lightbox[743]\"><img aria-describedby=\"caption-attachment-340\" decoding=\"async\" loading=\"lazy\" class=\"size-full wp-image-340\" title=\"Brass Threaded Thermoplastic Inserts last longer than tapping the plastic\" src=\"http:\/\/www.grassrootsengineering.com\/blog\/wp-content\/uploads\/2011\/09\/greng_2002.jpg\" alt=\"\" width=\"600\" height=\"450\" \/><\/a><p id=\"caption-attachment-340\" class=\"wp-caption-text\">Brass Threaded Thermoplastic Inserts last longer than tapping the plastic<\/p><\/div>\n<div id=\"attachment_340\" style=\"width: 610px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.grassrootsengineering.com\/blog\/wp-content\/uploads\/2011\/09\/greng_2003.jpg\" rel=\"lightbox[743]\"><img aria-describedby=\"caption-attachment-340\" decoding=\"async\" loading=\"lazy\" class=\"size-full wp-image-340\" title=\"Old Extruder next to the New Extruder\" src=\"http:\/\/www.grassrootsengineering.com\/blog\/wp-content\/uploads\/2011\/09\/greng_2003.jpg\" alt=\"\" width=\"600\" height=\"450\" \/><\/a><p id=\"caption-attachment-340\" class=\"wp-caption-text\">Old Extruder next to the New Extruder<\/p><\/div>\n<div id=\"attachment_340\" style=\"width: 610px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.grassrootsengineering.com\/blog\/wp-content\/uploads\/2011\/09\/greng_2004.jpg\" rel=\"lightbox[743]\"><img aria-describedby=\"caption-attachment-340\" decoding=\"async\" loading=\"lazy\" class=\"size-full wp-image-340\" title=\"New Extruder mounted\" src=\"http:\/\/www.grassrootsengineering.com\/blog\/wp-content\/uploads\/2011\/09\/greng_2004.jpg\" alt=\"\" width=\"600\" height=\"450\" \/><\/a><p id=\"caption-attachment-340\" class=\"wp-caption-text\">New Extruder mounted<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>It was time for a new plastic extruder head with better resolution, more measurable deposition and could compensate for slight changes in filament diameter without jamming.
