Inside the Mcor IRIS #3dthursday

3DprintedSkull

Here is some great information about the MCOR IRIS 3D printers as seen at Euromold by Fabbaloo.com, the ones that Staples Europe will be offering in their stores that use paper as the printing medium:

At Euromold 2012 we managed to get deep inside the Mcor IRIS color 3D paper printer. This device uses standard paper as it’s build material. Each layer (or page in this case) is formed by cutting the outline of each page appropriately. That’s perfectly understandable, but how do they print in color? 
 
The answer is flabbergastingly simple. The IRIS sits on a table, but in a secret compartment underneath there’s a standard Epson 2D color inkjet. 

The inkjet pre-prints color onto a stack of pages. Only a thin outline of color is printed on each page, corresponding to the outer skin of the object. The pages are printed duplex (both sides), with special ink designed to soak into the page, so you won’t see “white” page edges on your object. 

The pages for the entire object are pre-printed and collected in a large stack. Then this massive sheaf of paper is inserted into the 3D printer, which then pulls out its blade and goes to town.

But wait, you ask, “what if the pages are mixed up/missing/etc.?” We wondered that too and found that not only are the colors pre-printed, but a special bar code also appears on each page. The 3D printer verifies the correct page is in sequence for each layer. If not, it stops for you to print a replacement. 

The results are startlingly good. This 3D printed skull looks almost real. This is the print quality everyone will be able to access when Mcor’s deal with Staples enables 3D printing from copy centers.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!


We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
