Pistons, photo holders, and flowers

Hello everyone,

With the start of Fall semester this Monday, we are busy at the Wayne makerspace to be ready for the upcoming engineering classes.  Dusty is assisting  Professor Gold with student teaching the Tools for Engineering class.  He is fervently at work, designing a moving piston system.  Designing a complex system requires a fair amount of math knowledge, computation of angles, movement ranges, etc.:

In a couple of days’ time, he designed a working piston in CAD.  Not only that, but he also learned how to make assemblies, which combines multiple parts to form a working, moving part, right on the screen.

Check out the video of his working piston!

Thanks to our 16-hour workshop offered early this summer, I was able to glean enough information to create my very first CAD object!  It’s nothing fancy, but still quite an accomplishment.  It’s a 4×6 photo stand.  To create something in CAD, you draw and combine basic shapes to create new shapes.  In the examples below, a rectangle made the top stand while a trimmed circle created the “arc” stands below it.

Dusty embellished my design with three dimensional text that pushes through the curved surface:

A major accomplishment earlier this week was the second run of our filament maker.  A month ago, Will tore apart and rebuilt the extruder, as the original build (by me) was not precise.  By allowing a 4-5mm gap between the motor and auger, it dramatically changed the torque direction.  Now the extruder does not tear itself apart from the pressure.  We also mounted the extruder vertically, eliminating filament kinking as it cools.  Now we can reliably make our own filament at 1/4 cost of buying it, using low-cost pellets.  We hope to make totally free filament by recycling soon, too.

Last but not least, we received a request for table centerpieces.  Pam chose a number of attractive flower designs from Thingiverse, easily printable on our 3D printers:

Stay tuned for an exciting start of semester at the Wayne makerspace!

Did you know that Amazon has a 3D printing service?  You can customize objects to your liking, which are printed and mailed to you.

In the world of architecture, New York is about to receive the first entirely 3D printed home, including a printed swimming pool, four bedrooms, 2,400 square feet of living space, and more:

Our first workshop, fixing Polly, and window/door clips

Hello everyone,

It has certainly been a busy past couple of weeks!  We offered our first workshop in the new 3D Lab, composed of four days and 16 hours of training on CAD design, 3D printing, 3D scanning, building a makerspace, and more.  We hosted around 10 Northwestern Schools faculty & staff, community members, and a student or two.  Thanks to Dusty’s excellent lessons, the attendees really enjoyed the experience and will soon teach the concepts to their own students.  Thanks, Debbie, for taking photos!

We hope to visit the Orrville Boys and Girls Club soon to offer lessons to their kids on CAD designing, 3D printing, and 3D scanning.  More news coming.

Our portable printer used for offsite demonstration (affectionately named “Polly”) experienced a problem a couple of weeks ago.  The print platform would not heat to 100 degrees Celsius, which is necessary for prints to stick to the platform.  Thankfully the printer has a one-year warranty, so a replacement heating element was mailed to us ASAP.  Always ready for a challenge, Dusty had it quickly installed.

In the design department, Paul from the Daily Record brought a window clip that frequently breaks due to a weak design.  Dusty redesigned it with AutoDesk Inventor, but discovered that the dimensions were distorted when placed in the 3D printing software.  So he designed it again with Solidworks.  Not overly pleased with the printed clips from the Makerbox, we plan to print the clips with Polly soon.

Dusty also invented a clip for hanging items from the top of a door.  This was a special design because he taught his mother how to create it in CAD!  The clip works wonderfully and his mother is quite pleased.

We have a number of projects to complete with only one week before the start of classes.  It will be an exciting semester as engineering classes use the 3D printer technology for their various projects.  Stay tuned!

Thanks to a new company named 3D Babies, you can a fetus scanned and printed using 3D ultrasound images!  I am not kidding.  What a way to enjoy your tiny wonder for years to come:

In the world of prothetics, a 17-year-old creates a 3D printed arm using $250 of materials.  He made this for a fellow science fair attendee who would soon outgrow his/her $80,000 prosthetic:

Universal joints, bubbly lids, and a new 3D lab!

Hello everyone,

The summer has not slowed down activities of the Wayne College makerspace.  Thanks to Dean Deckler, the Maintanance Department, and Technical Support Services, we now have a full fledged makerspace room!  Please visit A-121 (outside  the previous location) to check things out and receive a tour.  We have plenty of room for our existing 3D printers, scanner, extruder, and expansion for future equipment.  There is a sink for chemical cleanup and a fan for future machines that need an exhaust.  And there is an eight-computer class area for offering workshops.  We have big plans for this room.

Dusty’s R/C car design (based on our engineering classes’ LEGO Mindstorms hardware) is coming along well.  He intends to build the car completely from 3D printed plastic.  His current project are universal joints used to turn the wheels.  It is a multi-part, multi printed assembly that works beautifully!

Dean Deckler challenged Dusty to create a thrust bearing, providing him with a metal model as a reference.  The on-screen design that he made is a work of art, though we have not printed it yet:

3D printed parts made with ABS plastic may have a rough look, especially if they are smoothed with sandpaper.  One trick we learned is exposing the part to heated acetone vapor.  The vapor slightly melts the plastic skin of the object, resulting in a glossy finish.  Ask Michelle Turner to show her Darth Vader pen cup to you for an example.

We recently tried to acetone-smooth a coffee cup lid that was 3D printed.  However, we exposed the vapor for too long, causing the plastic to boil and bubble.  So it is back to the drawing board for our acetone procedure:

Stay tuned as we report exciting development in-store for the new makerspace lab!

There are many companies producing 3D printers, though have disparate software that makes using multiple printers difficult.  AutoDesk (makers of AutoCAD) is releasing a software platform called Spark that can be used to support any 3D printer.  They are also going to sell their own 3D printer hardware:

3D printers are making their mark in space!  Not only does NASA have a 3D printer on the International Space Station for printing on-demand parts, SpaceX is using them to print thrusters for their SuperDraco spacecraft:
