an open 3D printing forum
We would like to share something we made:

Stay tuned for more details…
[…] awesome crew over at Open3DP at the UW have birthed a new species of open 3D printer: Adderfab! by Bre Pettis | Categories: Human Friends! | Enjoyed this article? Subscribe to the full […]
Coming from Lexington, Massachusetts, I would say that ranks up there with “The Shot Heard Round the World”
Dimitrios, thank you. We will be working to make it available and faster.
Nice!!!!! Great work, can’t wait to see more of this!
Erik, thanks. We’ll be working to make it faster and available.
Well done, can’t wait to see some details, thanks for sharing the powder recipe’s
John, we’ll release more details. We will work on this project over spring quarter to productize it and work out some of the details (like getting the speed up).
What kind of cartridge did you use?
Oleksiy, we are using an HP point-of-sale print head.
Fantastic work. The world really needs an open source powder bed printer so we can all try those powder recipes you have been sharing. The design looks very simple and elegant. Kudos to the design team
Kevin, thanks for the kind words. More cool things coming (we have something past 10 new posts coming)! So stay tuned.
You guys are _open_. Can’t at least minor bits of information get posted now? Could we get a description of the power that is used in the bed, and the material that is deposited by the print head?
Owen–details to come, we thought the video should have the first 1000 words…
Owen, tasty isn’t it. The printing material is one of the four new powders that we are releasing over the next couple of weeks! Sorry it’s not the next powder to be posted but
Congratulations! Looking fordward to see more of its capabilities! Regards 🙂
Congratulations! Amazing work. It seems a lot of interesting things are rising up this year and also keep others motivated.
Wow.. Congratulations..!! Can’t wait to see info
Details will be coming.

Congratulations – that is wonderful!
I’ve been following the antics on this site for a while. Really great work.
If you ever need mechanical help and/or know how commercial system solve some of the problems, I’d be happy to help.
Three key questions:
(1) Is this design to be open source?
(2) Is this printer capable of creating usable molds for clonedel reprap parts?
(3) What can we expect these to cost to make? (& how much is that print head?)
Andrew, nice email address! We will provide details as we always do. It may not be clear BUT we’re at a University AND we’ve been on break the past two weeks.
1.) yes that was part of the original design spec. This is OUR choice and has been from the beginning.
2.) yes. In fact, any 3D AM system can make the mold masters. We are hoping to re-design all the AdderFab parts to be moldable.
3.) Our goal cost is about $300-$350. Print heads are used in POS systems and thus widely available at a reasonable cost.
Are you using hp11 or hp85 print heads? Or something different all together?
Thanks in advance,
Jeff, we are using HP POS printing heads (as their are very available) currently but are exploring something else.
11’s or 85’s? Trying to determine if one has advantage over the other.
Thanks for the reply,
jeff, neither. I would choose a head that isn’t chipped (as you may need to do special things to deal with the chip).
By chipped you mean electronically chipped, correct? Sorry, somewhat new to the game. Thought they all were electronically controlled.
Thanks very much for your insight.
Jeff, no, some manufacturers build print heads with special chips that prevent them from being refilled, some provide date of manufacture, etc. These print heads are much more difficult to use in a DIY setting. If you’re trying to build a DIY 3D powder printer, then please look at HM3DP as it will provide most of the details to fab a 3D printer using an existing paper printer.
Thanks again for the info. We’ve been following your progress for quite some time and really appreciate all of the info you provide.
Our main hurdle has been software issues. We need the ability to print multiple models at one time (production runs) and most info available pertains to one-off type printers and/or software. Definitely making headway, though.
Jeff, our suggestion is purchase a used machine and take it off-road. It gives you access to good software and a large support community. Good luck.
Any thoughts on using thermal printheads over Piezoelectric printheads?

[…] If we are to be prepared, then, we must also be on the lookout for the long noses of innovation. These may be weak signals, outliers, ungainly things, as noses often are. We may not find such things among “best practices’ or among experts. Surveys of what is popular, also may not help us, unless we leave a big space for “other” and pay attention to maybe one or two responses there that are unlike anything else we’ve ever seen. Rather than dismiss these responses as insignificant, it may be that these are the very bits of the future we should be preparing for. To seek out innovation means to pay attention to minority experiences, not because it is politically correct, perhaps, to do so, but because it is where we will find, likely, our innovative future–in the rare event, the weak signal, the random thought, the experiment that failed, the silly thing that becomes the next steam engine or 3d printer.
