3D Printers You Might Not Have Heard About

In Uncategorized on 07, Dec, 2011 at 22:23

The Felix 1.0 can be found at FelixPrinters.com for about $1100. Designed by Guillaume Feliksdal because he has experience in mechatronics and he thought RepRaps took too long to put together and calibrate. The kit is mostly aluminum t-slot extrusions. It does not seem to be open source, but it is reportedly quick to assemble and calibrate, taking only 2-6 hours to go from zero-to-printing.

“…I love…to realize innovative technical ideas. The printer could also be useful for making my future inventions.” – Guillaume Feliksdal

The Orca 0.30, designed by Gubbels Engineering, can be found at Mendel-Parts.com. The kit is pretty much entirely steel rod and (anodized!) aluminum sheets, is about $800, and seems to be intended to be open source when the design is finalized.

The Mosaic, designed by Rick Pollack, can be found at MakerGear.com. The kit is mostly laser-cut plywood with pre-assembled precision linear guides, is about $1000, and doesn’t appear to be open source.

The Printrbot can be found at Printrbot.com. Designed by Brook Drumm because he figured people needed a printer that was a lot simpler and easier. The kit is about the most minimal combination of ABS and steel rod imaginable, is listed as $500 on the kickstarter page, and a lot of noise has been made about making it open source when the design is finalized.

The Prusa Air is Mecano’s redesign of the Prusa Mendel. It replaces a lot of the metal and plastic parts with flat sheet. Here it is on Thingiverse.com and the RepRap wiki. He says that the design evolved out of an attempt to make the Prusa more attractive and intuitive enough that someone could put it together after glancing at a picture. He has a version 2.0 on the way.

“Eventually I would like to see, apart from improvements in 3D printers, laser cutting open hardware, open hardware lathes, open hardware phones, etc” – Mecano

The Rook Printer by Jolijar can be found on Thingiverse and at Jolijar’s blog. He’s replaced the vast majority of the RepRap frame with t-slot aluminum and has redesigned the printed parts accordingly.

The Solidoodle 3D Printer, designed by Sam Cervantes, can be found at Solidoodle.com. This is a somewhat unusual design. Most of the functional parts are laser-cut wood, but the whole thing is enclosed in a steel frame that protects the whole printer. It only comes fully assembled for $700. The design doesn’t seem to be open source, but they do have a Facebook page. So you’ll have to make due.

The 3D Micro Printer is a stereolithography system that’s about the size of a large book and is only about $1600. It is the result of collaboration between teams led by professor Jürgen Stampfl and professor Robert Liska at the Vienna University of Technology. The prototype was developed by Klaus Stadlmann and Markus Hatzenbichler. The real strength of this approach, and the reason the overall machine is so small, is that it can be used to print very precise parts. This first generation prints in layers 50 microns (0.050mm) thick.

The following are even farther off the beaten path because they are CNC mills.

Don’t let that be a reason for ignoring them! Unlike a dedicated 3D printer, a CNC mill can do both additive and subtractive work (3D printers aren’t rigid enough to hold a carving tool in place without wobbling).

The MTM Snap has an exceptionally clever design. It was designed by Jonathan Ward at MIT’s Center for Bits and Atoms and it actually snaps together. Yes, snaps. The entire structure is rigid enough for milling but doesn’t include a single fastener. It is open source.

The White Ant was designed by Patrick Hood-Daniel and can be found at BuildYourCNC.com. Looks like it’s around $1000, but for that you get a machine that’s specifically designed to be either a 3D printer or a CNC mill. It’s a compliment to the book, Printing In Plastic, which takes you through the entire build process. It’s extremely hackable, as the design has been released under the Creative Commons license (free to reproduce) and, while it’s cleaner to CNC mill the wood pieces, the entire thing can be made in a garage with power/hand tools.

“I would like to see a machine that would be able to fabricate using multiple materials in one process…I will be developing an SLS machine kit in the near future.” – Patrick Hood-Daniel

ZEN Toolworks, owned by Xin Chen,  has several variations of a hobby CNC. They also have a very nice wiki for learning about their kits. The CNC mill is about $810 and they have a conversion kit for $80 that makes the build volume more suitable for 3D printing. They don’t sell any extruders and Xin explained that they don’t sell a complete kit (mechanical and electrical) for 3D printing because they figure it’s better to get 3D printing-specific electronics from somewhere else. However, you can pick up the mill itself (just mechanical) for about $450 and get the electronics & extruder from a different vendor. This product is not open source.

The micRo (yes that’s how it’s spelled) is available at micro.lumenlab.com for around $700. You’ll get the CNC mill which you can use for 3D printing if you mount an extruder or syringe. LumenLabs does seem to be working on a high-precision 3D printing addition to turn the micRo into the UNIFAB, but there’s not much information at the moment.

Maybe you prefer your projects a bit more…freeform. If so then check out how many 3D printers/CNC machines there are on Instructables.com.

So there you have it. The 3d printing world is a lot bigger than RepRap and Makerbot! The great thing is that more and more of these new designs are showing up all the time. Pretty soon there will be such a huge selection you’ll be able to find one that exactly suits your requirements. Additionally, the point of this post was little-known 3d printers. If you know of one that I missed please share that information with everyone else.

I’m Conflicted About Buildatron

In Uncategorized on 15, Sep, 2011 at 22:13

I have a few keywords like “reprap” and “makerbot” on my google alerts list, so I heard about this new company Buildatron. The link in my email took me to a press release that is responsible for the inner turmoil.

See…I want 3D printing to move into the mainstream. There’s only 4 years left until my inter-family prediction of “this stuff is totally going to be everywhere” becomes premature. I want to go to Wal-Mart and pick up a $100 3D printer that makes cell phones, and I want it now! On the other hand, I am convinced that the old people who own all the stuff and write all the laws are going to fill up their Depends when they realize the same people who pirate music and movies are now free to pirate physical products.

As is pretty obvious to anyone who bothers to look ahead: 3D printers are going to create some legal issues. With the Supreme Court ruling that corporations are people, and Congress worried that existing businesses might not pay for their reelection, it’s not outside the realm of possibility that 3D printing would end up strictly regulated. The exciting thing about desktop additive manufacturing is how much more efficient it makes people. That’s great for individuals, but not so great for existing corporations. Combine the threat of copyright infringement with the decreased revenue from simple (and not so simple) little gizmos and you’ve got a recipe for a new version of the RIAA.

It seems to me the best way to make that possibility unlikely is to push 3D printing into schools where it can give a whole new generation a reason to learn STEM. About the time industry lobbyists are marching around demanding regulation I want school kids marching around showing off how they invented a new pacemaker or something. That will even get the attention of industry (they need all the STEM geeks they can hire). Thus, creating a strong argument for allowing 3D printing to flourish with modest, safety-based regulation.

That’s my point of view, and I’m working on it (slowly; I have a day job). But then I see stuff like the Buildatron 1. The company’s press release stops just short of going “YOU get a car and YOU get a car and YOU get a car”…but then you click on the link.

They put a box around a reprap. Then they put their name on the box. Then they promised a revolution.

The best thing is that there are already companies selling reprap parts and kits assembled or disassembled. There’s makergear and reprapcentral and reprapstores and reprapkit and XYZprinters and botmill and techzone and I’m sure I missed some. Last but certainly not least there is Dr. Bowyer himself. And you know what? None of them bothered to brand an open-source project. Why does the Mendel need a box around it? I assume it was the only way they could create enough space to FIT a brand name in there.

I love open-source for exactly that reason. Since no one had ever thought of putting a big title on the machine there isn’t even any room to add one if you want to. It’s a marketing department’s nightmare.

See, Buildatron instantly invites comparison to Makerbot. Makerbot is from New York, so is Buildatron. Makerbot had 3 techie founders, so does Buildatron. Makerbot was based on the reprap project and so is Buildatron. Makerbot looks like a box…and so does Buildatron. Even the name looks copycat (build-a-tron, mak-er-bot). However, all that stuff is just surface. What seems significant to me is that Makerbot looks like a box because those guys actually designed a new printer. It makes sense for them to put their name on a product that was merely inspired by the reprap project. The Buildatron 1, however, IS the reprap project. With a box around it.

They didn’t even have the decency to make the box printable.

A  few of my favorite quotes from the press release:

Today Buildatron Systems announced the international launch of the Buildatron 1 3D printer…

Their offering represents a new paradigm in 3D personal manufacturing technology…

social network driven DIY (Do It Yourself) 3D printer kit.

We worked … industry leading customer support via Buildatron’s social network gateway

Buildatron’s opening of the 3D printer market to millions at industry shattering prices makes no bones about the impact they will have…

Buildatron is working hard to put you in the drivers seat by developing a new generation of tools unparalleled in history.

It’s just sooo cookie-cutter and over-the-top. They’re international because they have a website. They’re a new paradigm because they have a box. They’re social networking because they have a facebook page. They’re industry leading because there’s no industry to lead. They’re opening the market by sitting next to Makerbot at Makerfair. They’re unparalleled because they’re taking what everyone else is working on in a weird direction. The best part is that they could actually lower the price of their kit if they didn’t bother to put it in a box.

All of this leaves me conflicted. I want people to get involved in 3D printing who can hype it. Bre Pettis is awesome because he can get in front of a camera and really evangelize 3D printing. I don’t think an external control panel is all that important or useful, but I’ll let Makerbot do anything they want without complaint as long as they’re putting so much effort into building public awareness. However, the approach Buildatron is taking, right from the get-go, makes me want to tell them to stop.

You know who else saw what Makerbot was doing and thought it was a good idea? Well, Rick Pollack of Makergear and Erik de Bruijn of Ultimaker come to mind. They are both selling their own (branded) boxy 3D printer. But THEY DESIGNED NEW PRINTERS! The Mosaic and the Ultimaker are both brand new and innovative designs that take INSPIRATION from the open-source projects that birthed them. It makes perfect sense for them to give it a new name because it’s new. Buildatron just put a Mendel in a box.
