    Dollo 3D: Self replicating 3D printer

    Finally got one made. Z-axis was the biggest hurdle and it's not perfect yet, but it prints :). Next some tweaking to get the quality up; Z-has some twist, it's motion 'fluctuates' every 1cm or so (bausing uneven layer hights) and X-axis motor mount is too loose. But it works! woo!

    Dollo 3D: Self replicating 3D printer

    True, some of the problems can be caused by differences between printers, but i had to change the motor mount part about 1mm and i think that's quite much for varinace, especially when other parts generally fit. Then again i haven't measured what the actual prints are compared to the models... i'm using Slic3r and recently purchased Simplify3D.The Z-axis is an interesting idea, i think i'll play around with the current version just to see how well it works. Looking forward to the finished version.And i wish you luck with the kickstarter campaign, i'll pobably get me a kit even though i'm printing one :)

    Dollo 3D: Self replicating 3D printer

    In the NEW ties folder, the twist corner vertical grooves didn't fit the extention part and top ties where too tight of a match to get them fit on the next part.Also the motor mount was bit too tight for the rack to fit in the groove.I forked the github project, my modifications are here: https://github.com/spegelius/Dollo. If the changes are viable, i can create pull request to merge them. I think i did some kind of fix for the include-warning, too...I'm waiting for my summer vacation so i can continue with this project. Currently all parts are printed (i think, haven't kept that close count :) ), but haven't had time to assemble. I also need a plate for the bed, i was thinking about designing and printing somekind of frame, but don't know what it'll be yet.Nice project, the tinkerer ...see more »In the NEW ties folder, the twist corner vertical grooves didn't fit the extention part and top ties where too tight of a match to get them fit on the next part.Also the motor mount was bit too tight for the rack to fit in the groove.I forked the github project, my modifications are here: https://github.com/spegelius/Dollo.

    Dollo 3D: Self replicating 3D printer

    I started printing this a couple of weeks back. Got most of the parts printed for small Dollo, but still need to print some of the bow ties and long ties. Also need to design something to hold the bed.Some of the other parts needed haven't arrived yet, like RAMPS board and hot bed.I've had some minor problems with prints being too tight fit, but that's just problem with my print settings, been tuning them as i go and now the parts seem to be fine. Also the new long ties models have some mismatches that i fixed after forking the github project.I did start assembling the frame today and it does seem quite rigid. My plan is to make the smallest first and then increase the size, starting with the Z-axis.
