Next Weekend: The Midwest Reprap Festival

Guess what next weekend is? It’s the Midwest Reprap Festival, in Goshen, Indiana. We’ll also be there keeping tabs on an absurd amount of new RepRaps and other 3D printers, new filaments, and distributing a ludicrous amount of Hackaday swag.

The highlights of the fest include the folks from Lulzbot and UltiMachine, [Prusa] showing off his i3, [Nick Seward] and the Wally, Simpson, and Lisa RepRaps, and hundreds of other RepRappers showing off their latest projects and printers.

Here’s the best part: it’s all free! It would be cool if you register before making the trip out, but any way you look at it, it’ll be an awesome weekend. It’s also the largest US gathering of 3D printer aficionados that isn’t on the east or west coast.

Laser-Based PCB Printer

February 3, 2014 by 62 Comments

Being able to create PCB’s at home is a milestone in the DIYer’s arsenal. Whether you physically mill or chemically etch boards, it’s a tricky task to perfect. [Charlie & Victor] are working towards a solution to this complicated chore. They call their machine the DiyouPCB. DiyouPCB is an open source PCB etching project consisting of both hardware and software components.

The project is based on using a Blue Ray optical pickup. The pickup was used in its entirety, without any modification, to simplify the build process. In order to use the stock pickup, [Charlie & Victor] had to reverse engineer the communication protocol which also allowed them to take advantage of the auto-focus feature used while reading Blue Ray discs. The frame of the machine is reminiscent of a RepRap, which they used to do preliminary testing and laser tuning. The X and Y axes run on brass bushings and are belt driven by stepper motors which are controlled by an Arduino through a specially designed DiyouPCB Controller Shield.

Touring Deezmaker, The First *Good* 3D Printer Store In The World

January 23, 2014 by 24 Comments

When we visited the Crash Space hackerspace earlier this week, it came to our attention we were staying mere blocks away from Deezmaker, a 3D printer store in beautiful Pasadena that is home base for the Bukobot and Bukito printers, an awful lot of awesome printed plastic things, and [Rich] a.k.a [whosawhatsis], creator of the RepRap Wallace and all this stuff. Obviously a tour was in order.

Inside Deezmaker is a treasure trove of printed baubles and a fishbowl full of a herringbone planetary gear systems free for the taking. They have printers running all the time, a very nice lab for [whosawhatsis], and enough work space to host a few workshops every week.

In the video below, [Diego], the big cheese of Deezmaker takes us around the shop showing off his wares. [whosawhatsis] also makes an appearance showing off his latest invention, the Bukito printer. It’s a very small and incredibly portable printer that can be powered by batteries. They’re using a 3-cell 5000mAh lipo battery when they take the Bukito camping. I didn’t catch how long the battery lasts, but it’s more than enough to squirt out a few of the gear systems they give away.

Video after the break.

3DMonstr Printer: 8 Cubic Feet Of Build Volume

December 24, 2013 by 21 Comments

3D Monster

So you’re looking at 3D printers, but the build volumes for the current offerings just aren’t where you’d like them to be. [Ben Reylblat] had the same problem and came up with the 3DMonstr, an enormous printer that has (in its biggest configuration) a two foot cubed build volume, four extruders, and the mechanical design to make everything work.

Most of the ginormous 3D printers we’ve seen are basically upgraded versions of the common table-top sided models. This huge Ultimaker copy uses the same rods as its smaller cousin, and LeBigRap also uses woefully undersized parts. The 3DMonstr isn’t a copy of smaller machines, and instead uses very big motors for each axis, ball screws, and a proper welded frame. It’s highly doubtful anyone will call this printer a wobblebot.

The 3DMonstr comes in three sizes: 12 inches cubed, 18 inches cubed, and 24 inches cubed, with options for two to four extruders.  We caught up with the 3D Monstr team at the NYC Maker Faire, and from first impressions we have to say this printer is freakin’ huge and impeccably designed.

3D Printering: Making A Thing In AutoCAD, Part II

printering

It’s time once again for another part in 3D Printering’s series of Making A Thing. Last week was a short tutorial on the beginnings of making a thing in AutoCAD. This is an extremely complex software package, and in a desire to make things short and sweet, I broke this AutoCAD tutorial into two parts.

Since we already covered the 2D design portion of AutoCAD, part II of this tutorial is going to turn our 2D part into a three-dimensional object. Check out the rest of the tutorial below.

Custom Rostock 3D Printer Makes Use Of IKEA Components

December 18, 2013 by 9 Comments

After discovering 3D printers, [Turi] had to make one. This past summer he did, and it looks fantastic.

He chose the Rostock design not only because it can print big parts quickly, but also because of its mesmerizing operation. 3D printers are generally fun to watch for the first few minutes, but Rostocks tend to have an even more robotic appeal in the motion of its end effector (robotics lingo for tool head).

The cool part of this build is [Turi’s] choice of enclosure. He had an IKEA cabinet collecting dust in his basement, so he decided to make use of its drawers for the main structure of the Rostock. A bit of wood work and some matte black spray paint later, and he has one great looking enclosure! The rest of the build was pretty standard, making use of 3D printed parts, a RAMPS 1.4 control board mounted on an Arduino Mega, and a computer power supply. He did make his own control arms using carbon fiber arrows, though!

To see it up close and in action, check out the quick video after the break.

3D Printed, Solderless Circuits

3d printed board

If you’re looking for yet another alternative to etching your own PCBs, then check out this new Instructable on 3D printing test circuits!

[Mikey] decided to try out this method when he needed a small board prototype. He designed the perfboard to have a standard thickness—only 1/16th thick (~1.6mm)—with thin, recessed channels on one side and through holes on the other. [Mikey’s] circuit board allows you to stuff your components in, hold them down with a piece of tape, and then fill the channels with some kind of conductive material. In this example he’s used a highly conductive paint.

This 3D printed option probably won’t suit all your circuit-building needs, but it could provide an excellent shortcut for your next hack! As always, there’s a video after the break.
