Animated Bathroom Sign

Once upon a time, pants were created. After a while, women were allowed to wear them too. This has made a lot of people happy and been widely regarded as a good thing. There is a problem, however – bathroom signage is largely predicated on the idea that there are two rigid genders which all humans must be sorted into, and they’re defined by whether you’re wearing pants or a dress. [Robb Godshaw], among others, disagrees with this, and set about building a gender fluid bathroom sign.

The project seeks to exploit the traditional symbols of “male” and “female” – …read more http://pje.fyi/PQ3Mr7

Hackaday Prize Entry: Printing Bones

You would be forgiven to think that 3D printing is only about rolls of filament and tubs of resin. The fact is, there are many more 3D printing technologies out there. Everything from powders to paper can be used to manufacture a 3D model. [Jure]’s Hackaday Prize entry is meant to explore those weirder 3D manufacturing techniques. This is a printer that lays down binder over a reservoir of powder, slowly building up objects made out of minerals.

The key question with a powder printer is exactly what material this printer will use. For this project, [Jure] is planning on …read more http://pje.fyi/PL98yY

Formlabs Announces a Desktop SLS 3D Printer

Formlabs have just announced the Fuse 1 — a selective laser sintering (SLS) 3D printer that creates parts out of nylon. Formlabs is best known for their Form series of resin-based SLA 3D printers, and this represents a very different direction.

SLS printers, which use a laser to sinter together models out of a powder-based material, are not new but have so far remained the domain of Serious Commercial Use. To our knowledge, this is the first time an actual SLS printer is being made available to the prosumer market. At just under 10k USD it’s definitely the upper end …read more http://pje.fyi/PK3gNy

New Useless Machine Does The Twist

Useless machines might not do any work or produce anything of value on their own, but they can be a great learning tool, and are often beautifully crafted as an expression of the builder’s artistic talents. By and large, they consist of a switch to turn the machine on, and an arm that switches the machine back off in response to this. Vladimir had a different take, and built this twisting vase useless machine instead.

The build references the twisting vases we saw recently – [Vladimir] loved the way they so elegantly opened and closed, and decided to base the …read more http://pje.fyi/PJLNP4

Sexiest Tiny Metal Core-XY 3D Printer

That’s a lot of qualifications, but we’re pretty sure that you can’t accuse us of hyperbole in the title: this is one of the tightest little 3D printer builds we’ve ever seen. Add in the slightly esoteric CoreXY kinematics and the thick aluminum frame, and it’s a speed demon in addition to being a looker.

[René] had built a few 3D printers before, so he had a good feel for the parameters and design tradeoffs before he embarked on the DICE project. Making a small print volume, for instance, means that the frame can be smaller and thus exponentially more …read more http://pje.fyi/P0qrgY

MRRF 17: True Color 3D Printing

3D printing has evolved to a point where dual extrusion isn’t really that special anymore. A few years ago, a two-color frog print would have been impressive, but this isn’t the case anymore. The Midwest RepRap Festival is all about the bleeding edge of what 3D printers are capable of, and this year is no exception. This year, we were graced with a few true multicolor filament-based 3D printers. The biggest and best comes from [Daren Schwenke]. His Arcus 3D printer is a full color, CMYKW mixing printer that’s able to print in any color imaginable.

The electronics for this …read more http://pje.fyi/NmGfPS

Replica Fallout Terminal

If you’ve played Fallout 4, you’re familiar with the wall-mounted terminals in the game. They’ve got a post-apocalyptic aesthetic and the glowing green screen that calls out to anyone that grew up with computers and hacker movies from the 80s and 90s. Remember the first time you set your command line text to green? Don’t be embarrassed, we were all young once.

[PowerUpProps] liked the Fallout terminal so much they developed a replica. It’s a build that leans heavily on maker standards, a Raspberry Pi and 3D printing form the basis of the terminal. With ready access to such powerful …read more http://pje.fyi/NlpBc7
