Step 6: Putting it all together


- Two laser head slider mechanism with stepper motors (preferably matching), scavenged from old CD drives. Cost: a few bucks a piece.
- One InkShield kit, with ink cartridge and cartridge holder. Cost: $57
- Optional: additional HP C6602 inkjet cartridges. Cost: as low at $17
- Arduino Uno. Cost: $30
- Two SN754410NE H-Bridge motor drivers. Cost: $5
- Arduino prototyping shield and/or tiny breadboard. Cost: $4-21
- Wires, machine screws, standoffs, enclosure. Cost: Free to $$$, depending on how fancy you want to be.

Total cost for our version: about $150, shipping/handling for parts included. The pictures above show two different versions we made. The second one has a nice acrylic top plate, and a lot more space to put things in between.

The bottom CD drive mechanism moves the blue plate holding whatever you're printing on (such as an agarose plate). The top CD drive mechanism is set at a 90 degree angle compared to the bottom one, and moves the inkjet print head. We used Shapelock and some screws to attach the bottom platform to the laser head, and to attach the inkjet cartridge holder to the top laser head. The electronics consist of an Arduino Uno at the bottom, then the white InkShield (connected to the inkjet cartridge holder with a nice white ribbon cable), and then a protoshield with the stepper drivers on top.

The gridded paper strips on the bottom and top platforms allow us to track the position of the X and Y stages. Total print area is about 1.5 inch in both directions, with a resolution of 150 micron per step. Note that the resolution of the stepper motors is similar to the resolution of the print head: 96 dpi is a 265 micron pitch, but the dots printed by the print head are clearly separated - more like 150-200 micron.
could you use this to make leather
<p>here's the ebola strand :) http://www.ncbi.nlm.nih.gov/nuccore/10313991</p>
<p>(yes I am aware that it is not feasible to do this with this particular strand of ebola... or any)</p>

For printing in papers we use inks , but for priniting life cells what should we use ???????
<p>other living cells</p>
Soften any 'plastic', abs with a couple drops. Mix by weight 60% lacquer thinner and 40% acetone. (You can alao combine 30 to 35% ether and 65 to 70% naphtha to make a petroleum distillate but remember it's 72% volatile!) Use a suitable eye dropper non-plastic or rubber...some plastics are safe as applicators. For really small precision jobs use a suitable syringe. Polyethylene for example should be ok to use. <br><br>(You know the drill for safely dealing with chemicals...don't be stupid! Get a little help from someone who knows what they're doing and where) (http://www.uic.edu/sph/glakes/harts1/HARTS_library/solventhazards.txt)<br>This solvent works fine for making plastic welds and all sorts of plastic repairs.<br><br>Make sure to use lacquer thinner and not just toluene. The additives help make a close solvent to weld plastic. Check VOC's before you start. No MEK required but it's ok if in the lacquer thinner. (Thin out some ABS solvent and dissolve ground abs to make a great filler. <br><br>
Sorry just fyi...I'm a hack so check everything before trying to open a cartridge. I have very advanced training in industrial fabrication but the tinkering is just a hobby that I totally get for no explained reason.<br>Keep safe.
<p>I'm absolutely amazed. This work is truly fantastic. No other words than compliments and compliments. A little question.<br>Do you think is it possible using living animal cells to build an active layer for an enzimatic bioreactor like a sintetic belly - gut?</p>
<p>Wow very cool</p>
<p>Good work with printer.</p>
<p>This is a fantastic Instructable. Now I won't have to steal live kidneys anymore.</p>
<p>kidneys and eggs yum!</p>

<p>Amazing work!!!</p>
<p>Three words: Living Litmus Paper</p>
<p>Aren't the inks in inkjet cartridges alcohol based? Wouldn't it make more sense to put rubbing alcohol to clean the cartridges rather than just plain water?</p>
<p>Wow! This is amazing. Great job. </p><p>Congratulations guys!</p>
People are selling refillable ink cartridges now, so it might be much easier (and safer) to buy a cartridge that is designed to be refilled. (Although, you'd still have to open it up &amp; remove the sponge) <br>http://www.amazon.com/s/ref=a9_asi_1?rh=i%3Aoffice-products%2Ck%3Arefillable+ink+cartridges&amp;keywords=refillable+ink+cartridges&amp;ie=UTF8&amp;qid=1443536137
<p>Awesome work..</p>
<p>it is seems to be fantastic.us it possible to get the coding for the bioprinter ? if yes plss mail me </p>
<p>This project really very cool!</p><p>Iam impressed.</p>
<p>Hi ! <br><br>Great project . is it possible to get the codes used for the project. im trying to figure out how to use inkshield for a similar project of mine and im only a beginner :)<br><br>Thanks alot !</p>
<p>How about using a cnc milling machine to cut a precision opening in the top of the ink cartridges. Then another part could be machined to fit in the opening to close it. Look at the Othermill - www.othermachine.co/othermill as a suggestion.</p>
<p>clever, i'll give this a go when they come to town!</p>
<p>hello, does anyone have a sample of the arduino code? please email me abrarnourallah@gmail.com</p>
<p>Excellent project. Must try this</p>
<p>Interesting! But I have a question. What happened to the plate of E.coli on the agar plate? Wouldn't the cells eventually die off or if given nutrients grow so that the words were obscured? Is there any way to preserve the cells besides a picture? Or is deterioration inevitable?</p>
<p>I am working on a presentation for College, does anyone know what the price is? I would also like to know what will the market for this be? Will it be distributed to hospitals or will it be able to be used in small clinics?</p>
<p>Hi Alex! I visited BioBots website! When will the BioBots be available?</p>
<p>We are working on something similar over at <a href="http://www.biobots.io/" rel="nofollow">BioBots</a>. A low cost, high resolution, 3D bioprinter that is revolutionizing the field of regenerative medicine.</p>
<p>Extremely good...!!</p>
<p>Its really good :)</p>
<p>Really good</p>
<p>Thats astounding...</p>
<p>Its magnificent :)</p>
<p>Very cool!!</p>
<p>Thats impressive</p>
<p><br>Thats impressive<br></p>
<p>Thats excellent</p>
<p><br><br>Its extremely good :)<br><br></p>
<p>Reading this Instructable gives me chills!</p>
<p><br>Thats extremely good...<br></p>
