<\/a><\/p>\nInitially we had trouble with it, as there was intense torque between the vertical boards while plastic was pushed through the pipe.\u00a0 The boards would bend and crack from the pressure.\u00a0 Bracing the boards with additional wood did not help; we resorted to a 1\/4″ metal band that restrains the torque (thanks for the suggestion, Will!).\u00a0 The produced filament works wonderfully in our portable printer, so we are off to a good start.\u00a0 Here is a picture of Will repairing the extruder when the wood braces literally cracked apart under the pressure:<\/p>\n
Dusty made improvements to the geared heart box, as the original design from www.thingiverse.com<\/a> suffered from a weak crank which is compounded by tight gears.\u00a0 Instead of a small gear turning a large gear, he designed a torque reducing gearing system, strengthened the base, and designed a better crank.\u00a0 As a result, less force is required to turn the crank which makes the heart easier to turn as well:<\/p>\n Yesterday, Dusty and I made a trip to the Orrville Boys and Girls Club to demonstrate the 3D printer and 3D scanner, the latter of which was purchased by the Club and loaned to Wayne College.\u00a0 There were 30-35 kids in attendance.\u00a0 The energy from their excitement was thick enough to touch.\u00a0 The kids asked dozens of questions and were well behaved through the demonstration, so they certainly were interested.<\/p>\n We explained how the 3D printer and 3D scanner worked, then the kids designed cookie cutters using basic CAD design.\u00a0 We also handed out plastic cards that fold themselves into tiny velociraptors.\u00a0 It was quite a challenge for them.\u00a0 It was gratifying to see the kids so excited about the technology and engineering in general; a number of them asked some good questions about how it all works.<\/p>\n We hope to have more collaborative efforts with the Orrville Boys and Girls Club in the future, so stay tuned!<\/p>\n http:\/\/www.computerworld.com\/s\/article\/9248818\/Inside_Ford_s_3D_Printing_Lab_where_thousands_of_parts_are_made<\/a><\/p>\n <\/p>\n There are some big things happening at the Wayne College Makerspace in the coming weeks!<\/p>\n Tom<\/p>\n <\/p>\n P.S.

The most exciting announcement is the arrival of the filament extruder kit.\u00a0 Once assembled, we can make our own filament in addition to buying it in spools.\u00a0 That will save us 8-10 times the cost if the make the filament ourselves.\u00a0 It works by feeding plastic pellets into a hopper which is pushed to a hot end via an auger.\u00a0 The hot end melts the pellets and pushes out filament through a hole.
