CleanGreen3D’s paper-based 3D printer creates tough, durable 3D models that are greener and produce less waste.
Across industries, the benefits of 3D printing have made the technology a growing go-to for producing more cost-effective, efficient and lighter models, parts and products. While this method offers a significant reduction in waste over traditional methods, the available 3D printing materials—from plastics to metals—still have some downsides. There is also a greener, cleaner and more colorful option available: paper.
The thought of paper may seem like an unlikely and less-than-durable option, but CleanGreen3D’s CG-1 printer and related technologies quickly change that perception. Using a selective deposition lamination (SDL) method, the printer produces a finished model that is durable and more like reconstituted wood.
Although high-tech, this method relies on three seemingly simple ingredients: paper, ink and glue. The sustainably produced paper is made without optical brightening agents and is biodegradable and recyclable. The CG-1 is also designed to efficiently use the material, thus further reducing waste. The inks and glue are nontoxic and water based. The glue, which is a modified PVA, is also water soluble. With more studies revealing the potentially harmful sides of 3D printing in close quarters, this method produces no fumes, dust or chemicals, making it especially well-suited for use in nonindustrial settings.
Since a model is printed on paper, it better absorbs colors, as well as allows for printing more than a million colors at the same time. A photorealistic resolution ensures that the model looks the same on the computer as it does in real life. There are finishing treatments available for preserving or enhancing color. To hold true to staying environmentally friendly, plant-based M3A or lacquer-based M3B are the best options.
Similar to other printers on the market, the CG-1’s printing begins with a 3D data file that is read by CleanGreen3D’s control software, Orange. It determines the computer model into printable layers equivalent in thickness to the paper. The software also enables the user to
position the part, or several parts, within the 3D printer’s build chamber. While an operator is required to load the paper, the rest of the process is automated.
As each layer starts, adhesive is deposited. The machine presses it to the previous layer, as well as makes additional cuts, before the color is printed on the perimeter. The process continues until the printing is done. Once the printing is complete, instead of having to remove supports, use chemicals, or perform other tasks, the waste removal, which is called weeding, occurs. These small parts are easy to remove while leaving the model intact.
While paper may not be a viable solution in many cases, such as printing parts for machinery, it is an affordable choice for people working on prototypes and refining designs. Whether a manufacturer is developing new packaging, an architect desires a full-color model, or an educator wants a more hands-on approach to teaching, this method is fast and recyclable. For those wishing to explore this as an option, CleanGreen3D offers a free sample.
