Mcor IRIS: Full Color 3D Printing with Paper

I believe there are two key factors that are holding back 3D printers from escaping its niche. The first is the material used to build models – the filaments are made from plastic and are specific to each 3D printer. There is no true one-size-fits-all solution to printing material. Because these printers are limited to using one spool at a time the models are monochromatic – making true multicolor prints difficult to create.

MCor’s IRIS 3D printer solves these problems by using readily available 8.5×11 office paper and printing in “true colour” which they define as “realistic and accurate multicolor.” Using water-based ink, (this special ink permeates the paper ensuring colored edges in the final model) and glue, the whole set up is environmentally friendly.   Should you decide you don’t want a model anymore, you can simply throw it into the paper recycling bin. Compared to the usual plastics used in 3D printing, the IRIS is much more sustainable and cost effective.

The IRIS’s color printing capability is strikingly accurate, rendering lifelike models with little more than ink, paper and glue. When printing in full color, the IRIS pre-prints the design scheme onto the paper. Using a method Mcor calls “Selective Deposition Lamination,” the IRIS accurately places adhesive over an area which will become the part, then it sets a sheet of paper above it, presses it down to ensure a secure bond and then uses a Tungsten carbide blade to outline and create the edges of the model. IRIS does this for each layer until the part is complete. Even though it is made up of paper, a coat of water-resistant material can make the model waterproof.  SDL

We see the world in color, so why be stuck to a monochromatic models? The IRIS can help in several fields from architecture to medicine and industrial design. Designers can use colors to show specific textures and color blocking when it comes to products and buildings. With regards to industrial design, it can help give the customer a tangible idea of what the finished good will look like. The medical field can use these inexpensive, highly detailed models in the class room. On a consumer level, the MCor IRIS can create 3D photos where the subject pops out into the foreground.

I’m excited to be meeting with the people behind the Mcor in two weeks at the Rapid 3D Convention in Long Beach, so stay tuned for more updates!
