Saw this at World Maker Faire 2012, fell in love.

Will definitely be purchasing some injection molded parts from these guys!

Hope you're bringing this to Maker Faire Fort Wayne next month (Oct. 6
amp; 7)!... 8-)

BTW brought the H1 home to try and finish it over this weekend... this having a real job thing sucks the Maker time out of life.

Ok guys, since so many of you have asked/emailed, here it is!


Added a quick clip of the MAX running with the injection molded arms on our facebook page. Steve burned the midnight oil this weekend finishing up the molds and running the first sets of arms. So far, besides looking awesome, they work awesome. And, theyre lighter than printed arms, stronger and more durable too!



How does making a Delta using the effector general shape and the U-joint idea make this a derivative? And how can you call it an
gt;MAX without any association with or designed by the creator? DONT_KNOW

Hey there bstott. Did you get the parts we sent btw? It is a Rostock derivative in that we were inspired by his design, and we contacted Johann to let him know we wanted to build something along the lines of it. He said there were many people making changes, and that he wanted to add extruded rails to his design as well, so we had some collaboration with him in that front.

Thanks for checking it out!

Just take my money!!!!!!


Here's a quick video clip showing the linear Cheapskate slide in action. It's FAST, and with the 15 tooth pulleys I machined the other day, it ahs tons of torque


Why not using Makerslides?

We are using standard aluminum extrusions because the things like makerslide and openrail are hard to get, and just as, if not more, costly. Using regular t-slot, anyone can have access to the materials in a day or less almost anywhere in the world!

Absolutely - you must put this up on KickStarter ...

Thanks! We are talking about doing something like that. And, we are thinking of building 5 to have ready to ship if and when we launch a campaign, so you can have a chance to have one of the first rostockMAX's ever!

When will the kit be available?


I actually had the exact same idea for a parallel 3D printer

very glad to see you guys could actually pull it off.

We're working on all the little detailed stuff this week, and hopefully we'll be running production on kits next week! As we finish parts, and tool up for the molded parts (i.e. when the cad files are 100%) I'll be uploading the .stl files etc... Take a look at the rods, how awesome do they look! The injection molded parts have radius edges, and the main "beam" section is thinner, but it's glass-filled nylon, so it's SUPER stiff, and Steve just squared them up a bit to make them more printable for you guys

please put this on kickstarter :-$

Thanks sgraber, btw, I printed an origional this weekend too. Ya know, just for fun. Coming to the MakerSpace meeting tomorrow? BRING YOUR PRINTER!!!

Yep I'll be down. :) You bringing the printer to the MakerSpace meeting?

Of course, wait, which one? haha. I'll bring my H-1 AND the RostockMAX.

Anyone reading, if you're close to Goshen, IN come on down to the electric brew tomorrow night at 5-5:30, We meet there weekly for our makerspace meetup

I'll bring my Cupcake but we'll have to move to a corner because these steppers are loud! =-O
