How Cheap Can A 3D Printer Get? The Anet A8

The short answer: something like $200, if your time is worth $0/hour. How is this possible? Cheap kit printers, with laser-cut acrylic frames, but otherwise reasonably solid components. In particular, for this review, an Anet A8. If you’re willing to add a little sweat equity and fix up some of the bugs, an A8 can be turned into a good 3D printer on a shoestring budget.

That said, the A8 is a printer kit, not a printer. You’re going to be responsible for assembly of every last M3 screw, and there are many. Building the thing took me eight …read more http://pje.fyi/Q52230

What Actually Happens At A Hardware Hacking Con

The Hackaday Superconference was last weekend, and it was the greatest hardware con on the planet. What can you build out of a conference badge? If you answered “a resin-based 3D printer” you would have won a prize. If you decided to put your badge in a conference water bottle and make a stun gun you’d receive adoration of all in attendance. Yeah, it got that crazy.

At other tech conferences, you’ll find gaggles of nerds sitting around a table with MacBooks and Thinkpads. The Superconference is different. Here, you’ll find soldering irons, tackle boxes filled with components, and loose …read more http://pje.fyi/Q1WWbf

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
