Do we have a such thing? There are just about 10 inkjet heads manufacturers in the world. They produce about various industrial inkjet head types. There is absolutely no standard at all. BTW, industrial stuff is quite expensive. You can start with contacting head manufacturers like Ricoh, Xaar, Seiko, Dimatix and asking them for price quote and datasheets.

That dpi head is good enough already similar or close to the printhead i attached earlier. Its photo printing resolution grade no wonder its expensive Back in the day I had many artist friends and many of them owned large format inkjet printers that as far as I know did not use cartridges of any kind.

They filled them with bottles of ink. I had some friends who sold software that controlled them. This was 25 years ago. The prints their printers made were absolutely gorgeous. Crappy consumer inkjet printers are designed to break so you spend more money.

Its a false economy. And software. And mechanical transport. Also you will need to persuade head supplier that you are worth dealing with. Getting proper ink might be an issue too. Though some people make low grade inkjet printers, google might help here. Please participate in the discussion and bring your new Ideas for hacking the Head.This is an inkjet print head made using a RepRap.

The manufacturing process is both simple and ingenious. It uses a vibrating piezo buzzer to pump printing liquid through a tiny nozzle. The red disc seen above is exactly the same diameter as the piezo that resides behind it. There is a hole offset from the center to feed ink in between the two discs.

Take a look at the test footage after the break. To make the nozzle a hole was cut in the plastic disc, then a pin inserted and the whole thing was covered with hot glue.

Then when you print in full green you will get an equal mix of both parts in one pixel…. The current reprap works because the plastic cools almost immediately, giving it rigidity.

Danger, high voltage!!!! This evaporates leaving no char when you bake it in a domestic oven. The inkjet head should be a lot smaller than existing print heads. Any one can tell how to hack a printer to work with a vacuum black cartridge? You can thin down epoxy with acetone. That might make it printable. Might experiment one day. Hi Mike.

Would you be able to provide specs for this printhead setup? Any updates on this? This site uses Akismet to reduce spam.

There are many tips on the internet about unclogging the print head. Such tips range from helpful to detrimental for the printer. The mechanics behind clogging are simple. The print head is like a water tank with a very tiny opening.

During printing, the machine squeezes out microscopic picoliter ink droplets. The ink is designed to dry fast so as not to smudge. You can use water to dissolve or soften the blockage. Sit the print head in a bowl of water for few hours. Most print heads can be submerged underwater as long as you dry up the contact points before inserting back in the printer.

That is, the ink must be able to dissolve in ink. So the best solvent is the solvent that the printer manufacturer used to make the ink. Many ink manufacturers offer cleaning solution BCH offers such print head unclogging solution which works with both dye and pigment ink. If this is not readily available, use water. In most cases, water performs as well as cleaning solution.

Do not use cleaning solutions that contain corrosive ingredients such as bleach or alcohol, which will increase clogging in pigment ink. When you search for cleaning solutions, see if the seller also manufactures ink and if the package looks factory-made. There are cleaning solutions on the market that contain corrosive agents which will temporarily remove the blockage, but then your print head will be permanently damaged because it is corroded.

Since different substances are made from different atoms, increased temperature will affect their dissolving to different extents. Therefore, you should use hot water when you soak the print head.

There are some websites using fire to heat up the print head. We are not sure about the practice but want to show you that print heads can tolerate high temperatures.

Or, you can create suction from underneath. Be creative about this. Some customers showed us the suction chamber they made out of a rubber eraser. Most hoses can be bought at your local hardware store.

How to Make Inkjet Print Head Cleaning Solution

There are some examples of such tools on the web. Printheads are easy to be removed for HP and Canon Printers. For Epson, there are instruction videos on YouTube. However, as our reader point out, you are risking an electric shock. Bring it to Next Level: Ultrasonic Cleaner. You may want to invest in an ultrasonic cleaner like the one used in cleaning jewelry or medical equipment. An ultrasonic cleaner uses cavitation bubbles induced by high-frequency pressure 20 — kHz waves to agitate a liquid.

The agitation produces high forces on contaminants adhering to the print head. The ultrasound can be used with just water, but the use of a solvent appropriate for the print head enhances the effect.

Cleaning normally lasts between one to three minutes. Print heads must not be allowed to rest on the bottom of the device during the cleaning process because that will prevent cavitation from taking place on any portion of the object not in contact with water. Never place the print head directly on the bottom of the unit.After looking around, a group from University of Washington found that there were no DIY inkjet kits available.

Sad times. Parallax used to sell one, and the book Inkjet Applications by Matt Gilliland which went along with it, is no longer in print. Ganter do? The best part is that you can use it to print on all kinds of objects--paper, t-shirts, even mousepads remember those? The team's new printer prototype was constructed from steel rods and parts printed on a fused deposition modeling FDM machine --a piece of equipment that injects molten material in layers to form a part.

The group also found that they could cut the cost of printed parts in half by making silicon molds and casting the parts from polyurethane. Although the home DIY'er may not have the money to buy an expensive 3D printer, you might get away with using a DIY RepRap machine or by having your parts professionally and cheaply made by Shapeways.

After a little investment, you could also make your own silicon molds, just like what many people use to make wax molds for casting metal in invesment casting. The printer is based on an Arduino board ; the group used it because of the open-source platform's easy-to-use hardware and software, and because it's very cost efficient.

It should also have an option to print black and white with all four printheads for faster printing like I planned before for the 10 nozzle printhead instead of CMYK.

It would be a dream if it works out. I removed the 36V power supply, 3 LNs, the step down converter, the shift register, the WAGO clamps and the pump speed controller and added a 12V power supply, 3 more pumps, a much heavier speed controller and a step up converter. The printhead is now a 4 nozzle, single piece, height adjustable printhead for 4 different colors. I ordered cheap inkjet ink which I would mix with water for testing, but today I saw there is even cheaper ink out there which I could use without mixing it with water.

I tried to print a few pictures using water mixed with color. Since the last test with color I've increased the speed by optimizing the software and driver electronics and I solved the issue of continuous ink supply with a closed ink supply cycle and a peristaltic pump. I've added a Closed Cycle Material Supply System in form of a T fitting with some hose connectors, a Nema 17 stepper motor driven peristaltic pump, an extern stepper driver, a check valve and some silicon tubes to solve the problem of continuous material supply.

The pump pumps the material to the T fitting, which is mounted in the correct hight, so that the printhead neither leaks nor runs dry.

In the top of the T fitting is a hole drilled, so that the pump not influences the pressure between the T fitting and the printhead. A small amount of the material is used for printing, but the majority of it flows back to the tank.

This way there is always enough material in the T fitting to print until the tank is empty and besides of once setting up the right hight of the T fitting and refilling the tank when it's empty there is no additional maintenance needed.

I use a peristaltic pump, because that way the pump has no direct contact with the material which maybe could damage the pump or contaminate the material. Here is a test with all 10 nozzles online and speed optimized post processing script.The group set out to construct a low cost, open source inkjet printer for personal use that utilizes standard inkjet technology.

Their working prototype, pictured above, satisfies all of those requirements, making it an ideal device for the at-home hobbyist. The printer was constructed from easy to obtain components such as steel rods and stepper motors, along with other parts that can be printed using a RepRap or similar machine. An Arduino Mega manages the steppers and repurposed print head, recreating whatever Processing-generated image it has been given. The printer is quite a hit so far, and people are already talking about adapting the design to print on spherical objects think EggBotto create direct etch resist PCBs, and more.

We think it would make a great direct to garment printer with just a few small tweaks. Unimpressive… most of the technology of inkjet printing is in the print head… the part that they got readily made the whole cartridge. Now, what i really want to see is something like CISS that works better, every time, without problems. That would make a low cost solution. Fairly certain direct print etch resist only works with Epson piezo type cartridges and the yellow ink they use, not the HP ones unfortunately.

If someone has reverse engineered the mechanism for driving those, this could be a winner. Bogdan the reason the printers are dirt cheap is that the companies make revenue from the ink cartridges.

Scratchbuilt Piezo Printhead

Why do you think there are so many printers out there which does not let you refill and reuse the same cartridge or toner? I know that. That is the actual problem. They have used a ready made cartridge, which is where the technology really is, and no matter which model you choose, it is expensive. If the design was about making a good quality, cheap printhead. But I think such a design is well beyond hobby level.

You still do not get it. An open printer is also designed to LAST longer, to be self-serviceable or shop repairableand as this article points out… easily customized. You admit you understand the manufacturer sells these things below cost.

The manufacturer also designs inkjets to last very short times went through 6 Epson printers in 8 years at my home.

The manufacturer can afford to do this because of 2 things: vendor lock-in on expensive replacement ink, and taxpayer subsidized disposal of the device when it fails. Fact is electronics are routinely mixed in with common trash, and must be sorted out at the local landfill.

This is both unfair and not sustainable. Maybe initially, but print engines would go from being proprietary parts, to interchangeable commodity parts. What amazes me, is the guy make a printer, that skips the basic problem, the size and cost of the ink cartridge, and as you mention, the longevity of the product really is the issue. There is no social reason for planned obsolescence it is a factor of capitalism trying to supply in a system where it has to create demand. Although I think all the printing issues and costs are intentional to get everyone to have to use digital systems that can have the content monitored and changed when someone is targeted by some agency.This is an inkjet print head made using a RepRap.
