Printed a t-shirt! It ran out of ink at the end, but it came out great for the first try! It is hard to print white on black...so this should raise a few eyebrows.

Fantastic work guys, Bravo! Bravo. I wasn't expecting anything like that. You've got me really jazzed up again.

Yes guys the "Make your own T-shirt" is really cool.

Is the paint dispenser something you made or is it a kit you bought?

Do you turn on the air pressure by hand to pump out the paint?

It is a pneumatic transducer running at 50hz (for this demo). We control the xducer with PWM via EMC2/HAL. The xducer is fed 55psi from a compressor, and (for this one) allowed to vent on the negative stroke. I sourced numerous syringes with luer-lock fittings. The fittings include graded capillaries down to .004", but stainless tubing is available to .0005". The syringe is 'gas adapted' to the compressor, though I will try to use liquid CO2 next (quiet!). The Z can carry numerous 'depcaps' allowing for one-pass color printing, but more exciting; multiple 3d materials...what I guess I'm calling 'polyfabbing'.

Wow that is very impressive! It is amazing to see this in action printing white on black t-shirts as this is on of the (many) basic uses I would have for 3dp. There is so much more potential but this is very cool indeed.

I havnt watched all of the new videos you posted yet as im at work ... Grayson can you please give me some more info on the types of ink/dye/paint that could/can be used? Would it be easy to print multiple colours? Are you envisioning multiple print heads for the initial 3dp beta or would it be relatively easy and quick to switch colors by flushing out any previous ink/dye/paint that was in the system? Would it be possible or easy to add color to the UV curing polyester resins?

Hi Gav,

You can print with anything that is flowable through a capillary. Let me just say a big YES to all of your other questions.

One of my stated goals is to print a silicone hand with urethane 'bones', hopefully culminating in something usable! You can print color all at once by simply having a capillary for each of your desired colors. You can always use the micRo to manufacture any special mounts you might need, and we'll provide a few 'all purpose' pieces with the 3DP kit. (My name for it is the UNIFAB: the universal fabricator).

I've seen CO2 used for air brushing where compressors would be obnoxious, is that similar to what you have in mind?

Yes, here it is in one of these vids:

(For scale, the spiral we printed toward the end was about the size and width of a human fingerprint.)

Nice! Nothing like a little video to spread the good word...

Loving the playlist format of the posted videos, being able to sit back and enjoy instead of clicking and loading all those instances and making the browser slow. Also, thanks for posting videos, very fun to witness such progress!

what a great job guys, would be very nice to find some kind of ink resistent enough to print pcbs with this metod, looks posible at first view.

thanks for sharing all this stuff.

I must confess to sending Make the link... like many others I lurk around here, watching the awesome videos. (Yes people are watching them! ) When I saw the T shirt printing, I had to tell the world!

Awesome, thanks! Next up, a raster image of my face on my labcoat??

Go to like 12 seconds in of the 6th video. I got to say BC your forehead looks a lot like a majestic sun rise over the horizon.

What do you use to create those spirals? Is that a macro in EMC2, a python script, or hand-coded G-code or some other robin/brainchild-induced magic? I'm interested because one of my first projects for my micro involves cutting a pair of intertwined spirals (180deg out of phase), and for the life of me, I couldn't figure out how to draw that sort of spiral in Qcad.

Hi David,

Robin does most everything we do by hand. I can't remember the last time we CAM'd anything.

BC or Robin,

What are you using to print with? Just a die?

As I recall, it wasn't a dye, just thinned out paint

I did a small amount of T-shirt silkscreen printing in high school, I was surprised that the paint we used looked a lot like regular old household paint. It's been around 10 years but I still have at least one of those shirts, the paint is cracked quite a bit but the logo is just fine, that shirt is still in my regular rotation.
