Hello everyone,<\/p>\n

There is rarely a dull moment at the Wayne makerspace; the printers seem to be printing something all of the time.\u00a0 But not without problems, as each printer usually has some kind of issue to fix or workaround. \u00a0The build platform on the portable printer does not heat, the first printer is knocking down the object and needs its second extruder height adjusted, and the newest printer does not extrude filament consistently.\u00a0 Thank goodness for technical support and service plans!<\/p>\n

But apart from difficulties, we are having much success.\u00a0 Students in the Tools for Engineering class are churning out new robots each week as assignments are given.\u00a0 Next Wednesday, they will have robots that pick up a weighted ball, then determine how strong to throw it based on MatLab calculations into a box a set distance away.\u00a0 The weighted balls are being made on the 3D printers where the \u201cinfill\u201d (how much plastic is inside) can be changed for each object.<\/p>\n

Students drew the spheres in Creo, then printed them.\u00a0 We noticed that spheres with thin skins had difficultly printing, as support plastic on the underside of the spheres would tear away the skin of the ball, too.\u00a0 Designing the balls with a 2-3mm skin in Creo solved this problem.<\/p>\n

Neal (one of our non-engineering students) is hanging out in the lab, inventing interesting projects that involve LED lights, motors, soldering, and batteries.\u00a0 He is printing custom parts for his creations as well as using some of the failed prints from the \u201cjunk bin\u201d.\u00a0 He is quite creative.<\/p>\n

We received a request from the ADA department to create \u201cmedals\u201d for an upcoming Disability Olympics.\u00a0 100 of them!\u00a0 Dusty co-designed the medal and I am busy printing them.\u00a0 We are using homemade filament that mimics a darker \u201cmetal-like\u201d color of yellow.\u00a0 It is my second attempt with Solidworks and looks quite decent:<\/p>\n

We had an exciting evening last Thursday as members of the American Society of Mechanical Engineers (ASME)<\/a> came to visit the makerspace.\u00a0 Around 20+ folks listened to Dusty and I talk about 3D printing, mechanical design, and respond to a number of questions.\u00a0\u00a0 Some were interested in the accuracy and repeatability of 3D printed objects, to ensure part accuracy among multiple prints and how the properties of heating\/cooling plastic affects this accuracy.\u00a0 It was a very interesting discussion.<\/p>\n

Mark your calendars for October 18th as the Akron-Summit County Library hosts their first annual Maker Faire<\/a>!\u00a0 We plan to go as a group to see the 40+ tables of creations that span ages and generations of inventors.\u00a0 Please join us!\u00a0 If you wish to come along, please reply to this e-mail so that we can arrange the carpool from Wayne College that morning.<\/p>\n

See how Swedish students play a gig with entirely 3D printed instruments.\u00a0 It is a good example of using this technology for real-world applications:<\/p>\n

In another example, medical laboratories use syringe pumps to administer controlled, small amounts of liquid.\u00a0 The cost of new pumps can reach hundreds or thousands of dollars.\u00a0 Now researchers are 3D printing their own pumps at about $50!<\/p>\n
