Cheap 3D Printers Make Cheaper(er) Bioprinters

In case you missed it, prices on 3D printers have hit an all time low. The hardware is largely standardized and the software is almost exclusively open source, so it makes sense that eventually somebody was going to start knocking these things out cheap. There are now many 3D printers available for less than $300 USD, and a few are even dipping under the $200 mark. Realistically, this is about as cheap as these machines are ever going to get.

A startup by the name of 3D Cultures has recently started capitalizing on the availability of these inexpensive high-precision three …read more http://pje.fyi/PvlHrR

Refurbishing an old P3Steel

In the aftermath of the London Unconference, after the usual beer drinking networking at the pub, I meet Javier Varela, one of our many readers that were present. It turns out my fellow Iberic friend is involved in some interesting hardware projects, one of them being the OVM20 Lite board. I was looking for an excuse to mess around with my old Prusa and this was the perfect one. The P3Steel 3D printer was just getting dusty on my basement and it printed just fine in the past. Until one day…

Based on Arduino Mega 2560 with the RAMPS 1.4, …read more http://pje.fyi/PsR8NJ

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
