Yesterday at CES, Makerbot CEO Bre Pettis announced three new 3D printers, including a massive, fifth-generation Replicator capable of producing objects that are 45.7cm tall and 30.5cm wide/long. Interestingly, all three new models -- there's also a simple, one-button version and a desktop prosumer version -- sport clear plastic sides. 3D printers are very susceptible to disruption from even slight breezes (the wind cools the plastic between the nozzle and the previous layer) but there's a completely batshit patent on the totally obvious "invention" of putting see-through sides on a 3D printer, so in general printers don't ship with sides, and manufacturers don't publicly advise their customers to add plastic sides to their machines.
It may be that these patents have expired, or that
Eos Stratasys, Makerbot's new corporate owner, holds or licenses the patents.
Update: It appears that Stratasys does indeed hold the patents on putting plastic walls on your 3D printer to control the temperature.
The two high-end new printers also ship with scanners to make it easy to copy existing shapes, and internal cameras and small exterior LCDs so you can monitor the build in detail while it's in progress. There's also a cloud-based, easy modelling app for making new 3D shapes for your printers.
Additionally Pettis announced a store selling cheap 3D files -- $1 each -- that will co-exist with Thingiverse, Makerbot's repository of free/shareable 3D objects. It's not clear to me what relationship these two will have, though -- there's good reason to worry that the store will pick off the best of Thingiverse's stuff and put it behind the paywall, and that this will put the brakes on the collaborative improvement of designs that makes Thingiverse such a marvel. It'll be interesting to see how Makerbot manages this tension.

Samsung’s Galaxy Chromebook is unusually fancy and handsome for a platform usually associated with cheap, low-end machines, at least outside of Google’s own flag-carrier devices. How does it stack up? The Verge says its no good because despite the pretty case, high-end hardware and 4k screen, it’s unreliable and has poor battery life. Engadget thinks […]
CuloClean is a portable gadget that turns a plastic bottle into a bidet. I can’t vouch for its efficacy but it seems like a useful alternative to wiping your bum, especially as toilet paper has become a high-value currency. Apparently CuloClean supplies are also running low but it seems like you could make one yourself […]
Today apple announced a new MacBook Air (faster, cheaper) and an upgraded iPad Pro with LiDAR, “studio-quality” microphones and the full array of ultrawide and telephoto lenses as sported on recent top-of-the-line iPhones. But the thing that sells it to me is the new keyboard, which includes a trackpad (at last!) and fancy hinge that […]
Have you ever had more time to hone in on fine details than right now? Sure, at first glance, this might not seem like the time to get tripped up on the nitty-gritty of minutia. But how often are you ever going to have this much time to really stop and think about hows and […]
There are plenty of productive ways to spend time while stuck indoors. While it’s undoubtedly fun to binge all 15 seasons of Supernatural or sink days of playtime into an Overwatch campaign, learning something new is definitely a more meaningful and long-term beneficial use of open hours. And if you’re going to invest time in […]
Yoga studios are closed nationwide. The irony is that between the anxieties of the outside world and those popping up inside your very own home with everyone trapped indoors, there’s probably never been a time where yoga’s calming zen was more vital and needed. Rather than just throwing in the yoga mat and subjecting family […]
