Re: Mendel + Lego = MendeLego - 15 years ago
Short answer... I don't know. If I lean on things they bend, so I try not to lean on them. I've not got my z-axis sorted out yet but the x and y axis run on 5mm silver steel rods. I can flex those rods with my hands but that takes a fair bit of effort to do so. As for the joints. Yes, I can see that these could be a point of failure if the frame is put under stress.

Rich, I know what you mean about flex. That is my biggest concern at the moment. I have a mk4 makerbot plastruder here, which I think is going to test the design to its limits. I just need to find time it put it together. It'll be resting on those 5mm silver steel rods though, so I don't think there'll be too much flex in those. As for the rest of it, I'm current playing with the idea that Leby rob.m.clarke - General New Machines Topics

RichRap, Just wanted to follow up on the whole glue/no glue aspect. One of the things I wanted to do with MendeLego was to try and make it so that once you'd finished with your RepStrap, you could disassemble it and put the Lego bricks back into the pot for the next model you want to build. You can't really do that if you've used an ABS glue to stick the pieces together. What I have found isby rob.m.clarke - General New Machines Topics
Re: Mendel + Lego = MendeLego - 15 years ago
Thanks for the post. I've only had to "modify" a couple of Lego bricks so far and that was a conscious decision on my part. The holes in the bricks are 0.2mm off taking an M5 bolt and those are M5 threaded rods I'm using too. Take a look at that image, you can see the thread that is cut in the ABS when an M5 bolt is wound into the piece. The only real pieces I've modified are the white onesby rob.m.clarke - General New Machines Topics
Mendel + Lego = MendeLego - 15 years ago
Hi, I've been working on this off and on for a while now but I thought it was time to share where I'd got to and see what the rest of the community thought of this idea for repstrapping a Mendel type 3d Printer. All the vertices are made from Lego bricks. I'm going to go document where i've got to on my posterous blog. All opinions gratefully received. rob.m.clarkeby rob.m.clarke - General New Machines Topics
