What makes a good 3D printer for field work? It needs to be reliable, it needs to be durable, it needs to be reasonably portable. It also needs to print good, strong parts with decent resolution. They don’t have to be pretty, but they do have to work.
Last year, if you asked me what the absolute best 3D printer for field work was, I wouldn’t have hesitated to tell you it’s the Printrbot Simple Metal. This little beast has traveled the world with me, gone to sea, and taken an absolutely massive beating. And it’s still my main workhorse. At $600 plus a lot of custom modifications, it’s still the best deal in terms of quality, cost, and reliability out there.
If you can find one.
My Simple Metal, with the famous 3D-printed computer driving the 3D-printer that 3D-printed that computer.
Printrbot went out of business last year, due in large part to the proliferation of cheaper machines that have pretty good quality. The company sat in an awkward niche, too expensive for entry-level consumers, not quite up to par for people looking to drop several thousand on a professional machine. As important as it is to me, “can you kick the crap out of it and drop it off a boat?” is not a criteria that rates highly for most people who want a low-cost machine that will sit comfortably on a desk forever.
But that puts me in an tough spot right now. Conservation Tech, especially low-cost, open-source conservation tech, is booming, and we need machines that work in the field on the budget of a conservation biologist. I couldn’t tell you what the best cheap 3D printer on the market is right now for people who need it for field work, travel, or just want a tough machine that works and doesn’t cost much.
So I’m going to buy a bunch, beat them to hell, and figure it out.

Hagfish appear to use slime to avoid predators like sharks (top) and large fish (bottom). The images above are from videos showing fish eating a hagfish, which then produces slime and is able to escape (Images from wikimediacommons).
It’s month two of the longest shutdown in US history and there’s only one party who won’t allow a vote to reopen the government proceed. Have you called you senator today?
Ministry hints Putin’s Arctic ambitions are not realistic. There is unease in several Russian government ministries as officials start to understand that the President’s objectives for the Northern Sea Route can not be reached. The only way to please the president might be to expand the sea route itself.
There is controversy whenever a human creates a close interaction with a wild animal. Those arguing in favour of the human’s behavior inevitably settle on the argument that if the animal didn’t like it, the animal would have bit them or exhibited some sudden reaction to the human. People who propose this argument have a … Read More “Why I don’t bite everyone that stresses me out: The cost-benefit analysis of predators” »
The Rio Grande Rise is an almost completely unstudied,
geologically intriguing, ecologically mysterious, potential lost continent in
the deep south Atlantic. And it also hosts dense cobalt-rich crusts.
The Rio Grande Rise is a region of deep-ocean seamounts
roughly the area of Iceland in the southwestern Atlantic. It lies west of the
Mid-Atlantic Ridge off the coast of South America and near Brazil’s island
territories. As the largest oceanic feature on the South American plate, it straddles
two microplates. And yet, like much of the southern Atlantic deep sea, it is
relatively under sampled.
Almost nothing is known about the ecology or biodiversity of
the Rio Grande Rise.
The US Government enters it’s third week of shutdown over Trump’s Border Wall. Democrats in the House passing funding bills identical to the one unanimously passed by the Senate. Despite that, McConnell won’t let those funding bills come to a vote in his Senate. The Republicans own this travesty.
The future of fitness tracking is here! reStepper is an open-source, arduino-powered machine to walk your fitness tracker after those unfortunate workouts when your steps didn’t get logged. Did you have the audacity to take you child for a walk in a stroller? Get those steps back! Were you foolish enough to go swimming when you could have walked in aimless circles around the pool? Don’t let the credit drift away! Reckless enough to do something, anything, that might require you to take off your jewelry before working up a sweat? Let the reStepper sweat it all back! Maybe you just don’t want third parties to know where you run, or where your secret morel patch is, or how fast they need to make the people harvesting machines in order to catch Charlton Heston.
The reStepper, an engineering marvel.
Ummm.
It’s funny.
So what is it?
The reStepper is an open-source machine that “walks” a fitness tracker for you.
Hagfish. You love them. I love them. Of all the fish in all the seas, none are more magnificent than the hagfish. Across the world, children celebrate the hagfish by making slime from Elmer’s glue, their own mucous, or just, like, something. Seriously, how is is that toddler hands are always coated in some strange, unidentifiable slime?
2018 was a big year in hagfish science. Below are just a few of my favorite studies.
Biogeography
A hagfish in the high Antarctic? Hagfish have previously never been observed in the shallow waters around Antarctic, but a photograph from 1988 was determined this year to be a hagfish feeding on a large pile of clam sperm in shallow water. Neat!
Possible hagfish at 30 m in Salmon Bay in 1988. The white patch is Laternula elliptica sperm.
Incidentally, the reason the photo languished for so long is that it was originally though to be a Nemertean. Because Antarctic Nemertean worms are huge and horrifying.
Pirates! Robots! Meteors! A team of plucky teenage explorers! If this doesn’t end up as a feature film, I’ll eat my red watch cap.
On Monday, February 6, 2017 a meteorite dropped out of space and dropped right into Lake Michigan. Since then, a team of young explorers sponsored by the Shedd Aquarium and the Adler Planetarium have been combing the lake for the lost meteorite. Catch up with this epic adventure through their podcast and on OpenExplorer. The search continues into 2019.
Not all hydrothermal vents emerge in the deep sea. Of the coast of Iceland, shallow water vent spew forth their hydrothermal plumes in the shallows, where small underwater robots can easy access. You’d think we’d know more about them than their deep ocean counterparts but we actually know less.
On a hot summer day in the murky waters of the man-made Millbrook Quarry in Northern Virginia, a group of about 25 people outfitted in scuba gear take turns going down to a depth of 30 feet, testing their compass reading skills, flooding their masks and practicing emergency ascents without air. The sight is not so unusual since Millbrook is the main training and certification site for scuba divers in the DC/Maryland/Virginia area and often hosts such groups. What might give folks pause, however, is that upon closer look they may notice that all 25 of the divers are African American. And if they chat with this unexpected bunch, they might also find that a majority are certified and qualified to search for, document and help excavate slave trade shipwrecks.
Divers with Purpose and the Slave Wrecks Project will be traveling across Africa and the Caribbean documenting the stories of underwater archaeologists working to preserve the history of the Atlantic slave trade buried at sea.
