Yesterday the Trump Administration unveiled its proposed budget for fiscal year 2020. This budget contains steep cuts research, education, and social services in order to fund the construction of the border wall. Chief among the cuts is an unprecedented reduction in funding for NOAA, which functionally disbands several core research programs within Ocean Services. From A Budget for a Better America:
“The Budget also proposes to eliminate funding for several lower priority NOAA grant and education programs, including Sea Grant, Coastal Zone Management Grants, and the Pacific Coastal Salmon Recovery Fund.”
Rumblings on the hill suggest that Secretary of Commerce Wilbur Ross plans to unveil his own plan to drastically reduce the budget of the National Oceanic and Atmospheric Administration and permanently hamstring NOAA in furtherance of the Administration’s goal to find funding to construct a wall on the US southern border.
These cuts include zeroing out the budget for the following agencies and programs:
NOAA Coastal Zone Management Program
National Centers for Coastal Ocean Science (NCCOS)
Pacific Salmon Restoration Program
Potentially at least one fisheries laboratory
These cuts would be catastrophic America’s Coastal Communities and Economies, especially in places like North Carolina, Maryland, and Louisiana.
How cheap can a 3D printer be and still function? Although they seemed plucked out of science fiction, there’s not really that much to these machines. A few stepper motors, some switches, a control board, a heating element, and a nozzle are really all you need. It’s the software, and the expiration of a bunch of patents, that kicked the 3D printing revolution into high gear.
Is it possible to assemble the right collection of components to make a functional 3D printer for less than $100? iNSTONE thinks you can, and they are not wrong.
Monoprice, the king of rebadged 3D printers, has two entries in the sub-$200 printer category. We already dug into the guts of the Mini Delta, a great little delta-style printer, and now it’s time for the Monoprice Select Mini! This is a pretty standard cantilever printer, with the x-axis tied to the print bed and an y-axis connected by a single support to a moving gantry. It’s basic, but solid, with a bare-bones set of features that gets the job done.
There is also a Select Mini Pro which, since this review series started, has been discounted to $199. It does look like it has some nice features that make it wort the extra $11, including an automatic bed leveler, magnetic build plate, and touch screen. The budget for this series is blown, but if Monoprice wants to send us one *hint hint* I’ll be happy to put it through the wringer.
You can buy a 5-lb bag of polymetallic nodules from the Clarion-Clipperton Fracture Zone on Amazon, right now.
Depending on your vantage point and how long you’ve participated
in the deep-sea mining community, this will either come as a huge surprise or be
completely unexceptional. Prior to the formation of the International Seabed
Authority, there were no international rules governing the extraction of
seafloor resources from the high seas. Multiple nations as well as private companies
were engaged in exploration to assess the economic viability of extracting
polymetallic nodules and tons of material was recovery from the seafloor for
research and analysis. Some of that material almost certainly passed into
One of the reasons 3D printing exploded seemingly overnight a decade ago has a lot to do with the RepRap project, an initiative to build a fully open-source and largely 3D-printable 3D-printer. The idea of a machine that could replicate itself was pulled straight from the pages of science fiction, and yet, here were machines–janky, kludgey, barely functional, machines–assembled from parts clearly fabricated by those same machines. They were conceptually impressive, but not a particularly awe-inspiring sight to behold.
And then came Josef Průša and the Prusa Mendel.
Affectionately known as the Ford Model T of the 3D printing world, the Prusa Mendel was the first of the open-source 3D printers that was designed to be easily mass produced. It looked good and it ran great. Released under an open-source license, it was replicated and iterated on a massive scale. That didn’t prevent Průša from building a successful company. The current Prusa i3 MK2 is among the most successful desktop 3D printers in the world, and certainly one of the best.
Clocking in at $197.69, the Anet A6 is the most expensive printer in this review series. It’s also the biggest, with a massive 220mm by 220mm by 250mm build area. It’s an upgraded version of the popular Anet A8, with a larger build volume and a better user interface, but not much else. From reviews, this printer seemed like a solid representation of what you can get at the top end of the menagerie of sub-$200 Prusa i3 clones. It (and its smaller A8 brother) certainly have the fan-base and hacking community to support its reputation.
This acrylic-framed beast ships as a kit, so expect to spend half a day putting this printer together.
If you’re going off of dollar per cubic millimeter, this is the best bang for you buck by a wide margin. And that’s about the extent of the good things I have to say about this machine.
Monoprice is an interesting organization. They’re a rebadging company that seeks out unbranded or off-brand products, makes a few tweaks, and then sells them to secondary markets under their own brand. They made their mark in the early 2000s selling good, cheap cables and have expanded from there. You can find headphones, cookware, cables, computer accessories, and, of course, 3D printers, under the Monoprice label. But that doesn’t mean their products are cheap knockoffs. Monoprice has a reputation for finding quality equipment.
The Monoprice Mini Delta is a rebadged Malyan M300. From the specs, it doesn’t look like Monoprice changed anything but the logo, and that’s a good thing. Malyan printers have a great reputation.
This is a delta printer, which means rather than having independent X, Y, and Z-axes, three identical stepper motor arrays work in tandem to control the position of the extruder while the bed itself remains stationary. It uses a Bowden-style extruder that keeps the weight on the printhead down. It has an aluminum frame with steel structural elements. The relatively small circular print area is 110 mm diameter by 120 mm height. Controls are integrated into the printer and it allegedly has WiFi capability through an app.
