MarkForged Tips & Tricks

MarkForged is excited to announce a new series of “Tips & Tricks” videos for the Mark One printer.

The video below demonstrates “Cleaning the Nozzles” on the Mark One and was produced by MarkForged’s Sr. Application Engineer, Dan Topjian.

 


MarkForged Mark One Used to Print Nylon-Kevlar Unibody for BattleBot

DDTv3: The 3D Printed Nylon-Kevlar Combat Robot

DDTu v02.2 adad DSC_0564

DDT v3’s debut was at Dragon Con 2015 where it had four matches and went 3 wins, 1 loss. I am extremely happy with its performance and the resiliance of the printed frame. I half expected the weapon shaft bore to open up after so many hits (including arena wall hits) but it remains as true as when it was first made, probably due in part to the heavy kevlar fill around the critical dimensions. DDT’s fights are embedded below. I was very lucky to not fly out of the pit on several occasions but unfortunately my luck ran out when a solid hit on Algos sent DDT flying into the pit.

Another Great 3D Printing “Case” Study from Our Partners at Markforged

Caddytown – 2 parts, a socket and power bit caddies – Created by Carl Calabria

 

The potential for 3D printing is limited only by your imagination.  Here is a great “case” study from our partners at MarkForged, innovators and manufacturers of 3D printers and systems. For questions about 3D printing or Markforged printers, contact Miller 3D.

3D printing caddy

 

Carl created caddytown in OnShape to house his ever-growing power-bit and socket collection. Both are printed in these pictures in nylon, without composite reinforcement. The nylon is actually great for this application because you can flex it slightly to pull out one of the bits. The nylon will bend slightly many, many times without cracking.

You could absolutely print this on a Mark One with a composite base, too. Eiger will add some fiber layers for you, or you could add some yourself. Adding a few fiber layers to the bottom could help the part print flat and add some stability, but this design works better using the compliance achieved with nylon – the bits fit snuggly and are easier to get out based on the way MarkForged’s nylon slightly flexes.

The socket caddy is also special for another reason. It’s specific to a Wera socket set that long ago parted ways with the socket holder. Carl was able to quickly model this holder perfectly suited to the size of these sockets.

Different socket sets may have different diameters than this tray. If you’d like to reuse it, the best bet is to scale the part to fit your sockets.

Carl submitted this part as a contestant in MarkForged’s internal “Part Of The Week Competition.” It was a close race, but Carl was first runner up. He lost to a shamelessly submitted customer part, that will be posted on the blog as well. You can also see this part on Thingiverse.
