Fun With Ingredients
With the campaign winding down, we wanted to share some additional details on the hardware and components used on the DeltaMaker. To borrow a line from Papa John’s, “Better Ingredients, better printer.” Let's talk about some of the ingredients that make a better printer.
The brains of your 3D printer is not the place to save a few bucks. We have evaluated the boards currently available on the market and feel that the Azteeg X3 is the best of bunch. We are locked into this board and this will ship on all of our printers. To see more about this board, please check out www.panucatt.com.
Linear Bearing System:
MakerSlide aluminum extrusions paired with Delrin v-wheels on bearings. This provides a linear motion system much more robust and rigid than found on many low-cost 3D printers and kits. This also retains a clean and elegant finished look, while still allowing the user to see all of the mechanical workings. For more information on MakerSlide, check out buildlog.net.
Delta Arms and Rod Ends:
The arms and rod ends are a potential weakness in delta designs. Flexing of the arms, and high friction in the rod ends, limits accuracy at high speed. DeltaMaker arms are constructed of 6061 aluminum tube with low friction, lightweight IGUS rod ends. This provides a very stiff, lightweight solution while allowing for the high pivot angle (+/- 40 degrees) necessary for the design.
Drive Pulley and Timing Belts
The DeltaMaker utilizes GT2, closed-loop, timing belts in its design. The drive pulley is all aluminum, with 20 teeth. This size, combined with 1/16 microstepping, provides the right balance of speed, torque, and resolution for this application.
What about the printed parts on the prototype?
Production DeltaMakers will contain no printed components. These parts will be replaced with a combination of aluminum, engineered plastics, and injection molded components.
How fast can this thing go?
We have run motion tests as fast as 200 mm/s on prototype hardware (video coming to YouTube tonight!). As printed parts get replaced with production hardware, we will go faster.
Thanks for supporting the project!
