#MRRF
Midwest Reprap Festival 2019 also known as MRRF is the most incredible 3d printer convention on the planet. It may not packed with suit wearing industry experts like some additive manufacturing trade show 3d printing events but it has the potent diy hacker way of life ingrained into small but thriving community. The reprap convention is like no other event and can only be described by the experience itself. The small venue in Goshen, Indianna holds the most enriched gathering of 3d printing enthusiasts. Compared to previous years there were many more people attending or exhibiting. The venue was packed to seams with some of nicest 3d printer builds you can find. The Reprap Project founder Adrian Bowyer would be amazed at what this creative community has morphed into.

The Best CoreXY 3D Printers of 2019
3dGloop Tug of War.
White Knight 3D Printer
Some of you might remember the Black Belt Printer. The Black Belt was a useful closed source belt 3d printer with a infinity Zaxis. Carl from NAK3DDesigns published an open source version mechanical concept called White Knight 3D Printer. The White Knight is a great design and well built machine.
Carl used his experience in automotive body work and applied these skills to his build. The results were great. The finished product looked like a finished product. You can find out more about the White Knight on his Thingiverse Github accounts. Just search white Knight belt 3d printer.
3D GLoop, a start up selling their new bed adhesive on Kick Starter present their solution to a common problem in the 3d printing area…… bed adhesion. 3D Gloop is the most insanely strong bed adhesive you’ll ever see. At the end of the three day event, 3D Gloop set up the “3D Gloop 3D Printed Tug of War Challenge.” To demonstrate the strength of their bed adhesive they brought out a strap with two piece 3d printed handles. Then participants played a round of tug of war to show how strongly 3D Gloop held its bond. In addition to bed adhesive they also have a new 3d printed part spray coating that works very well and a glue that is used to glue 3d printed parts together. It’s very impressive of how well this product works. It just works. They invested much time and even hired a scientist to develop the most useful product. I know we’ll be stocking up on some soon.
E3D definitely left an impression on the 3d printing community last year when they presented their new CoreXY 3d printer equipped with a tool changer. Although the final design hasn’t been published yet that didn’t stop many from making their own or similar inspired machines. It’s amazing how quickly the RepRap community can develop and implement an idea. Many exhibitors showed their own version to the tool changer technique. While there was a small number of exhibitors that had the genuine E3D corexy printers that were sent out to early beta testers. I don’t know if tool changing 3d printers will be the feature of 3d printing multiple materials and colors but it’s a good start. Plus it gives them a reason to buy more of their great hotends. Who says you can only have a couple of hotends on a 3d printer?
The E3D tool changing corexy printer uses the Duet Wifi with the X5 expansion board to control the advanced motion system. They mentioned before how they wouldnt be able to control the printer like they do without the Duet Wifi and Reprap Firmware. The gcode based programming and configuration allows for useful macros to be utilized to get more functionality.
he Midwest Reprap Festival also has the most interesting 3d prints you possibly find. Its hard to not get inspired by all the cool stuff people 3d print. I think we also broke the record of the most 3d printed tug boats you can fit into one building( benchies.)
his interesting delta 3d printer build was designed and built by Ryan Carlyle. Ryan also wrote the book “3D Printer Engineering.” I picked up a copy from him at the show and this is what I think…… The book is great. Coming from someone who has built a handful of printers it showed me alot of information that connected the dots of machine design to the actual science and technical engineering. You can find the book on Amazon and highly suggest you add this one to your collection. This book is great. It doesn’t matter if your newbie or designed and built a number of machines there is something there for you.
