[Aldric Negrier] is no stranger to the 3D printing world. Having built a few already, he designed and built an SLA/DLP 3D printer, named RooBee One, sharing the plans on Instructables. He also published tons of other stuff, like a 3D Printed Syringe Pump Rack and a 3D Scanning Rig And DIY Turntable. It’s really worth while going through his whole Instructables repository.
This open-source 3D printer was inspired by the Cristelia – SLA/LCD 3d printer and the Vulcanus MAX 3D printer (that he designed). RooBee One has an aluminium frame and an adjustable print area of 80x60x200 mm, with up to 150x105x200mm build volume using an ACER DLP projector. In addition, a fan on top of the printer was added to extract the toxic vapours outside and away from the printer operator. The electronics are based on the Arduino MEGA with the RAMPS 1.4 shield and one NEMA 17 stepper motor. As for the Arduino Mega firmware, [Aldric] choose to use Repetier, which he usually uses in his other printers.
The SLA resin he used is the Standard Blend Resin from Fun to Do Resins. These resins tend to release toxic airborne particles, so extra care should be taken to ventilate the area while printing and also do a proper cleaning afterwards.
You can get a glimpse of the printer making a small gear come to life in the following video:

In this Instructable, [Wayne Mason-Drust] shares the step by step guide on how to make a cool, good-looking, 3D printer based on the Ikea LACK table. From an Ikea lantern weather station to a fully printed CNC based on an Ikea table, it’s almost safe to say that a 3D printer Ikea hack was overdue.
The idea to use a Ikea table as a base for a 3D printer first came to [Wayne] as he used this table to support other 3D printer he had working in his business. He realized that, even after five years of use, the table showed no signs of wear or distortion. So he decided to start to work on a 3D printer based on this precise table, the one that used to hold the printer.
[Wayne] stacked two together and named it Printtable (pun intended?). This open source, cartesian rep-rap 3D printer looks pretty slick. With a build area of 340mm X 320mm and 300mm on the Z axis and a price tag for the parts starting as low as $395, seems like a pretty decent 3D printer. With some work sourcing the parts, maybe it can be even lower.
Or we can just wait until Ikea starts selling them.

T’is the season to hack, and the maker brigade won’t disappoint — there’s no better way to crank out a few cute holiday tchotchkes than to fire up the 3D printer. [Niklas Roy] has released gDraw, a software package that creates G-code to print out 2D drawings on your 3D printer.
The interface is simple, allowing the quick and easy creation of basic vector drawings. The program then converts the paths in the drawing to a G-code representation that your printer follows to squirt them out in plastic. Think of it as the 3D printed equivalent of the “Stroke Path” tool in Photoshop.
[Niklas] chose to demonstrate the software by creating some interesting greeting cards that Big Christmas is sure to rip off next year and sell for $30 a pop. The printed plastic drawings give a fun 3D effect to the cards, and we’d love to see more examples of art created with this technique. The software was designed to work with the Ultimaker 2, but with tweaks, it should be able to generate code for other printers, too.
We’ve seen plenty of great festive hacks over the years — like this awesome laser projection setup.
A new version of the Printrbot Simple was released this summer, and this sleek new model includes a few highly desirable features. The metal enclosure was improved, linear rails added, a power switch was thrown in, and the biggest feature — a touch screen — makes headless printing easy.
Adding a usable display and achieving reliable WiFi are big engineering challenges, and thanks to the Internet of Things it’s only going to become more common to expect those features. How did the Printrbot team implement this? [Philip Shuster] recently released a write-up of how the Printrbot Printrhub came together.
The story of the display and WiFi module in the newest Printrbot begins about a year ago with a post on Hackaday. [Philip] built the Little Helper, a little electronic Swiss Army knife capable of basic IO, sending out PWM pulses, sniffing I2C, and a few other handy features. The Printrbot team reached out to [Philip], and after a few conversations, he was roped into the development team for the Printrhub.
Departing slightly from the Little Helper, the Printrhub features the same microcontroller found in the Teensy 3, a 2.8 inch TFT display, capacitive touch sensor, microSD card slot, and an ESP-12 module to handle the WiFi connection. The display system was tricky, but the team eventually got it working. Using an ESP8266 as the WiFi module for a printer is more difficult than you would think, but that works too.
One of the more interesting challenges for 3D printers in the last few years is the development of a good printer display with wireless connectivity. Yes, those graphic LCDs attached to an Arduino still work, but a display from 1980 doesn’t sell printers. In just a few months, the Printrbot team came up with a relatively simple, very elegant display that does everything and they’re releasing all the hardware as open source. That’s great news, and we can’t wait to see similar setups in other makes of 3D printers.
The holidays are almost here, and with that comes the traditional Mass Consumption of Consumer Goods and Gift Exchange. 3D printers are getting really good and really cheap, and it’s inevitable that a lot of 3D printers will be given as gifts this year. Be careful if you’re giving or receiving one of these printers: they can cause fires as [Ben Hencke] found out when diagnosing a problem with a printer he bought this year.
The printer in question is the Monoprice Maker Select V2, a Prusa i3 clone with impressive specs for a $300 printer. This printer is a rebranded Wanhao Duplicator i3, and we’ve reviewed it favorably. It’s a capable printer that beats the pants off of any Kickstarter printer in quality (and for the fact that you can buy it right now). We’re pretty sure there are going to be more than a few of these printers under the Saturnalia tree this year.
After a few weeks, [Ben] noticed a bit of smoke coming from the printer while the bed was preheating. This wasn’t blue pixie smoke, like you’d find from an exploded capacitor. There was a lot of smoke.
After a closer inspection and help from [Elecia White] from embedded.fm, the problem was traced to the power connector for the heated bed. The green, bromine-infused plastic for this connector was charred and there’s little doubt this could have caused a fire.
3D printing is a fantastic tool, and has enabled more hacks and builds over the last few years than we could have ever imagined. 3D printers are getting very good, and very cheap, and of course this will eventually mean someone losing their workshop to a printer fire. Until someone figures out how to build a ‘thermal fuse’ or something of that nature, 3D printers — from the high-end ones to the still very good Monoprice and Wanhao units — have the potential to start a fire.

He’s a little cagey about the reasons, but [Ivan Miranda] plans to put a drill press on the internet. What could go wrong with that?
We’ll take [Ivan] at his word that there’s a method to this madness and just take a look at the build itself, in the hopes that it will inspire someone to turn their lowly drill press into a sorta-kinda 2-axis milling machine. [Ivan] makes extensive use of his 3D printer to fabricate the X-axis slide that bolts to the stock drill press table. And before anyone points out the obvious, [Ivan] already acknowledges that the slide is way too flimsy to hold up to much serious drilling, especially considering the huge mechanical advantage of the gearing he used to replace the quill handle for a powered Z-axis. The motor switch was also replaced with a solid state relay. The steppers, relay, and limit switches are all fed into a Teensy that talks to an ESP8266, which will presumably host a web interface to put this thing online.
The connected aspects of the drill press become a little more clear after the break.

Cartesian 3D printers were the original. Then delta printers came along, and they were pretty cool too. Now, you can add tripteron printers to the mix. The tripteron is an odd mix of cartesian and delta. The system was invented at the robotics laboratory at Université Laval in Quebec, Canada. The team who created it say that it is “isotropic and fully decoupled, i.e. each of the actuators is controlling one Cartesian degree of freedom, independently from the others.” This means that driving the bot will be almost as simple as driving a standard X/Y/Z Cartesian printer. The corollary to that are of course delta robots, which follow a whole different set of kinematic rules.
A few people have experimented with tripteron printers over the years, but as far as we can see, no one has ever demonstrated a working model. Enter [Apsu], who showed up about a month ago. He started a post on the RepRap forums discussing his particular design. [Apsu] works fast, as he has now demonstrated a working prototype making prints. Sure they’re just calibration cubes, but this is a huge step forward.
[Apsu] admits that he still has a way to go in his research – especially improving the arm and joint implementation. However, he’s quite pleased that his creation has gone from a collection of parts to a new type 3D printer. We are too — and we can’t wait to see the next iteration!
