    But they've been printing in zero-G on the ISS for over a year now. I would think radiation and extreme temperature gradients between the light and dark sides of a print would be the most...

    I think what Jeff is picturing is the old Thing-O-Matic setup. There were two big problems with that setup that are solved with using the belt as a "z-axis" of sorts.
    First, when the belt was used...

    Jeff has a point, controlling the layer orientation of a part on this would probably require a raft tilted off the belt to be parallel to the gantry. That would end up being a very thick raft in...

    Z-axis in relation to the direction of the layers. It has a limited envelope in which it can print any given layer, but an unlimited number of layers it can print.

    I remember seeing Bill Steele's prototype of this at Rapid 2016. it really makes sense for him to team up with Printrbot to bring it to market, as the form factor doesn't really match with the rest...

    There is a "clone head" function in the firmware, just set two of the heads to be a clone of the one you've selected to print in the slicer and they all print synchronously, making three of the same...

    Yeah, and it's about the size of a small cargo van. None of the teaser pictures of it had a way to show the scale, but that thing is at least 5ft (or 1.5m) tall.

    Hyrel 3D was there, we had a blast showing off our next-generation printer to the public for the first time. We just had a small booth way at the back of the 600 row, so I'm not really surprised...

    Well in my case, I got my Peachy and within days of finishing it, closed on my new house and have been super busy with it ever since (it's a fixer-upper to put it nicely). Right now it's actually in...

    While it certainly is cool, I'm a bit confused on how it is supposed to work in zero gravity. I'm either misunderstanding the process, or they are leaving some major details out of it.

    Well this is great and all, but we've been doing exactly this for over a year now at Hyrel.

    I welcome them to the market of UV-Crosslinked silicone printing, but if they claim they invented the...

    It seems like this is only good for fixing small bits of cortical bone and maybe small skin repairs. Even simple skin grafts seem to require micro-structures to work properly.

    That said, this pen...

    It looks like it has timing pauses pretty often for when two heads are predicted to be too close, which makes having those wipers pretty essential. The flying Gantry style of the bigger machine cuts...

    I know just what you're asking about and while I've got some great ideas for a multi-filament mixing head, I can't confidently say they're developed enough to be called plans just yet.

    I'm gonna second CA's sentiment, Aside from some mechanical specifics, the Aether1 is almost the same as the Hyrel System line of printers. The main difference is that the Hyrel SDS heads are...

    I think that a lot of people have sort of given up, but not in a loud and angry way. Because in the grand scheme of things $99 one time years ago isn't worth a rise in blood pressure.

    It's the kind of problem that has been plaguing online artist communities for decades now, which is why most sites give an actual copyright to their members' submissions. I'm pretty sure Creative...

    As for the rest of this, I have to agree that a story about Reddit being offended is about as informative as one about 4chan being offensive.

    I find it rather interesting that they seem to be using the exact same spindle motor that has been on the Hyrel Drilling/Milling head for about a year now. That said, I agree with awerby, even with...

    At that size, you're looking at a rather large hibachi grill.

    In fact, re-purposing a commercial flat grill might be your best bet... Good luck.

    It seems like complete overkill at first glance, but the dual motors are great for putting lots of controlled pressure on the filament. This makes for very quick prime and unprime actions and is...
