Now Accepting Dogecoin!

Good news, everyone!

Today we are announcing two things:

First, we are now accepting Dogecoin for our 3D printing services.  If there’s something you want such as a cover for your Google Glass camera (, or a stand for your Google Glass(, or something which doesn’t at all relate to that product at all –  we now quote prices in Dogecoin!  (Yes, we still take BTC and LTC).  Much additive manufacturing!  Such adoption!


For over a year, CryptoPrinting has seen steady interest, which we have been able to service without scaling: If many orders and requests arrive, we will likely have to start a waiting list until we can scale up to deal with demand. (I say this particularly for the benefit of our BTC and LTC customers who may have come to expect fast service, which I would not want to give up providing. The second announcement is regarding #Dogetags!  Yes, we are working to develop an NFC-capable Dogecoin simulacrum, which you can use to do all of the things you could do with our water-resistant NFC tags, such as:

  • Store your private keys (wrap it in foil to prevent stray scanning)!
  • Store a single private key and become your own bank;
  • Store your public address so that others can scan it to pay you;
  • Theoretically you might store a variety of public addresses for different coins, so that people can pay with what they wish (still looking into this).

Additionally, we realized that you could use CryptoPrinting’s #Dogetags as real-world dogtags and store your contact info on a little 3D printed tag attached to all your canine pals!  Or use your dog as your bank and keep the private key on him!  You do what you want to do with it; out-of-the-box thinking encouraged.  Very printed, much wow!

Since we’ve already received positive responses about this idea, we’d like to get serious about it. This is where some community involvement would be great because:

1. For something like this to be useful to people who are trying to use them to keep their pets safe/have their pets returned promptly, we would need some kind of awareness campaign to make sure people recognize these tags and are aware that their NFC capable smartphones can retrieve the dog owner’s data.  We need a little bit of assistance spreading the broader idea of this #Dogetag project, which will hopefully be an open source, decentralized, opt-in, pet identification system.  Please join in on the conversation here:

2.  We need to choose a consistent model or models to help facilitate #1, which we could make a fun contest out of.  There are a few Dogecoin models on Thingiverse but they all have different problems, either in their design, or some kind of non-manifold STL, which resists repair. If there’s anyone experienced with running a fair crypto-driven contest, we would like some input on how to do it well. Model Design requirements: We need a recognizable coin with a hole in it, which is sized to allow an NFC tag to be inserted during printed without overlapping the hole.  In general our other coins are around ~3.8cm in diameter, for comparison.

3.  I cannot possibly supply the larger needs of pet lovers alone should this catch on.  In an effort to deal with this proactively, while also celebrating one year of operation, I will be open sourcing the NFC coin-making process, hopefully giving anyone with access to NFC stickers and a 3D printer the tools required to make their own #Dogetags.

Here’s the plan:

1. We need to solve the 3D model/STL problem first through the design contest.  I’d like to make it as democratic as possible with rewards going to the winning designer, but if we can reward all participants – great!

2.  Once the model is chosen and I’ve made sure that the NFC/printing part is working, the open sourcing of the process will be developed so that others can make their own coins.  From there on out it’s mostly an information campaign “If you find a dog with this on, scan it and return them please!”  Anyone who wants one can make their own, and those who want to purchase one are welcome to do so.

3.  After that point, CryptoPrinting will take orders until I’m booked solid, then I’ll start looking to scale our local operation, build a more distributed printing network as needed, or otherwise rely on people to create their own #Dogetags.  Such a network would also need some decentralized reputation network to build off of, which I’m not sure exists yet.  Either way, very excite!  Much opportunity!

 It’s a brave new world in Cryptoland!

NFC+BTC Protips

Dear Cryptofriends,
I wanted to pass some information along that will be useful to you and anyone else who happens to want to use our NFC for Bitcoin/altcoin related purposes (particularly putting a public address on an NFC tag for others to pay to).
Unfortunately, with the closure of BitMit and a slapdash attitude toward record keeping on my part, a large fraction of my customer’s email addresses have been lost (if I ever had access to them in the first place).  I like to think that this shows I’m not the kind of person to hoard your private information, as opposed to revealing that I am a scientist/engineer trying to play business-creature, but take it as you will.  The practical result of this is that it is difficult to communicate privately with all of our past customers and we think this information is worth sharing more broadly anyway.
If you find the information valuable, please consider tipping the OP, whose address is listed in the reddit post.
All the best,

Bitcoin without BitPay

Bitcoin without BitPay

CryptoPrinting (a.k.a. 3DP 4 BTC) is no longer accepting Bitcoin payments via BitPay.  We would like to take a minute to explain this change.

Let us start off by commending BitPay for the service they provide.  For those who want to accept bitcoin without having to hold bitcoin – or otherwise deal with the legal uncertainties associated with it – BitPay surely is a useful service.  We still support both BitPay and the brick and mortar services that use it.

That being said, CryptoPrinting was started with cryptocurrencies in mind – without any intention of accepting fiat at any point.  It was never intended to replace our day jobs, nor could it.  For a service like ours, BitPay lessens the impact of using Bitcoin as a payment solution by adding unneeded fees.

BitPay operates by taking a small fee from each transaction.  However, their payout process typically takes longer than it takes us to fulfill each order.  It also acts as a communication barrier between us and our customers since we need certain customization info like the type of NFC tags desired in order to fulfill orders.  Finally, BitPay does not provide escrow, so your trust in our service is still needed.

As we continue our search for alternative escrow solutions, we ask that you please contact us directly for negotiation and payment: [email protected].  Thanks!!

CryptoPrinting’s Positive BitMit Feedback

BitMit CryptoPrinting (1)

While CryptoPrinting has always been open to users submitting 3D printable designs, our NFC-enhanced simulacra have been useful for getting our name into the cryptocoin space.  Bitmit in particular has been a strong source of sales and feedback from our start in late February, 2013.

With Bitmit closing down, we thought it might be worth publicly posting our 100% positive feedback record for posterity, as what is currently publicly available information will soon be turned to digital dust.  Since BitPay has no escrow option, trust is needed more than ever for those ordering directly with us for the first time.  We’d like to point out that we’ve tried to make maintaining that trust a priority through our service record.

If you have any suggestions on how to keep improving our services, or have a suggested replacement venue with features comparable to Bitmit, please post your thoughts below.

CryptoJunky Review: 3D Printing For Bitcoin – Combining Disruptive Technologies


3D Printing For Bitcoin – Combining Disruptive TechnologiesWhat happens when you combine two of the world’s most disruptive technologies? That’s what the newly formed site 3DP4BTC is exploring as they offer custom 3D printing for Bitcoin. That’s right, you can now order anything a 3D printer can produce with a purely digital currency that you help run from the comfort of your home. Welcome to the future ladies and gentlemen. Also referred to simply as Crypto Printing, 3DP4BTC is the intersection of two burgeoning technologies, 3D printing and Bitcoin. 3D printing has been grabbing a lot of headlines as the technology is continually explored and expanded. For instance, Venture Beat recently reported about a project combining 3D printing and augmented reality. It’s not surprising that Bitcoin and 3D printing have been combined considering all the attention the two have garnered recently. In fact these two also happen to be the focus of Seed Fund Boost VC, who recently announced they’ll be focusing on Bitcoin for this summer’s incubator batch (Boost VC and Crypto Printing aren’t directly related). Boost is sector and stage agnostic but have current interests in consumer tech, 3D printing and Bitcoin related companies. How CryptoPrinting Works Crypto Printing showcases their NFC-enabled Bitcoin and Litecoin simulcra under their shop section. Purchasing these is pretty straightforward. Just add your choice to your shopping cart, enter your shipping information and checkout with BitPay (If you’re unfamiliar with BitPay it’s the same service I used in our recent NameCheap review). The simulcra are offered for $17 per Bitcoin/Litecoin or $30 for the pair. While these NFC-enabled simulcra are their flagship products, they’re not the only offerings from Crypto Printing. In fact they offer custom 3D printing. So with a few Bitcoin at your disposal you can now print pretty much anything that a 3D printer can produce. Just use their custom orders form to provide them with a STL file and your contact information. They’ll then get back to you with a price and any other pertinent information. My Experience I’ve been pretty intrigued by 3D printing after learning of the low cost of MakerBots as well as a slew of new models. Still I haven’t had the funds or the time to really try the process out yet. Crypto Printing offers a pretty simple way to get started with 3D printing without the overhead cost or time of buying and setting up your own printing. I decided to start out by ordering a few of their Bitcoin and Litecoin simulcra. To be exact I ordered one Bitcoin simulcra with a NTAG206 NFC tag, one Bitcoin simulcra with a Mifare 1k NFC tag, and one Litecoin simulcra with a NTAG206 NFC Tag. After printing the Crypto Printing staff informed me that one of the Bitcoins had a slight blemish on the edge which I opted to keep so I could tell the two different tag types apart. Once they’d finished printing Crypto Printing sent me a photo of the finished products. They gave me the choice to pay in Bitcoin or in Litecoin.

Our Crypto-Coins Are Waterproof & Buoyant!

For those of you holding our NFC-enabled 3D-printed cryptocoin simulacra ‘in the wild,’ we would like to give you a product update: your custom-printed coins are all WATERPROOF!*
Bitcoin Dunk - Top Down
We recently decided to test out our cryptocoin simulacra to see how waterproof they really were.  The results?  Not only are your coins waterproof, but they also FLOAT!!  The printing process traps small pockets of air into the coin, which allows it to float!  After giving it a short bath (with dunking), the NFC tag inside didn’t have any functional (read/write) problems at all.
For a while, we were confused why the NFC stickers we embed into your 3D prints were not considered ‘waterproof,’ while other NFC tags were.  What makes one of these tags waterproof?  It turns out that it’s all in the plastic coating around the tag.  This coating prevents the device antenna from becoming deformed or otherwise breaking when the tag gets soggy.  In that sense, embedding the tags into our 3D prints might be considered it’s own kind of waterproofing.
*We will be conducting a similar test of longer duration soon, but thought that this information was worth passing along.  That being said, anyone who has already written a private key to their tag should continue to exercise all due caution.  You wouldn’t dunk your laminated laptop into a bathtub, would you?

3DP 4 BTC Now Accepting Litecoin!

As of 4/2/2013 it costs 15 litecoins per 3D-printed NFC-enabled litecoin simulacra (or bitcoin simulacra) with domestic shipping included.  Add 5 LTC for international shipping.

Our fledgling operation has managed to satisfy a few customers so far (see here, but instead of being swamped by orders, we’ve been left pondering – Might people be unwilling to spend their bitcoins?  Is the speculative aspect dominating the utility of exchange?  Or is the market for custom 3D printing just already swamped with other services?

As we started a printing service for BTC to expand the marketplace/economy associated with it, we decided that in that spirit we should begin accepting LTC as well.  So we are now happy to accept litecoin for 3D printed stuff!

We are looking for a trustworthy escrow service which accepts LTC if anyone has one in mind.   We are also looking for a suitable model so that we might offer this little ‘trifecta of technology’ of 3D printed NFC-enabled litecoin chits, if there are any designers out there who might be willing to give it a crack.
