You might soon be able to 3D print wood
Posted By Lucie Gaget on Mar 20, 2019 |
We are now able to 3D print a lot of different materials, and researchers continue to be interested in the development of new 3D printing materials. Today, let’s talk about this new project of 3D printed wood, developed by researchers from Columbia University! They managed to 3D print digital wood. How? What are the possibilities offered by this experiment? What are the different possibilities we actually have to 3D print wood? Let’s discover it right now!
3D printing wood: Is it already possible?
A new experiment has been led
Could it be possible to 3D print wood with the same quality we now print metal, plastic or resin? Maybe soon. A new manufacturing technique has been developed to 3D print wood, or should we say, to 3D print parts looking like wooden parts!
The resin blocks developed by the researchers look just like olive wood! The huge challenge of wood 3D printing is actually to recreate the external and internal texture of wood. Engineers from Columbia University actually used voxel mapping to create objects with a rich internal structure.
In order to mimic the structure of wood, they had to expose and go through a 3D scanning process of the internal structure of a wood sample; obviously not the easiest thing to do. Engineers used a special technique they called destructive tomographic imaging. This process involves slicing the wood using a 3040T desktop CNC machine, with a camera controlled by a program taking consecutive images. Each slice was 27 microns in height corresponding to the layer height of the 3D printer used in the study.
Images of the wood sample had to be scaled to match the printer’s XY resolution, and then, the RGB images were converted into a CMYK standard, to fit the requirements of the 3D printer used for the experiment. Thanks to all of that, a GrabCAD voxel file has been made using all of these information.
What about 3D printing wood filament?
Scientists from Michigan developed last year a technique allowing 3D printing with wood filament made of… wood waste! Recycled wood might be the next solution to print a wood project. Indeed, using a process in four different steps, scientists succeeded in creating a filament made out of wood waste and PLA plastic.
In order to do that, the wood waste has been transformed into powder and then heated with PLA pellets. Once it is cooled down, the mix is solidified and … Here is the wood filament!
Perpetual research of new 3D printing materials
If you follow our 3D printing blog and receive our newsletter you should know it: a lot of 3D printing material research is made to increase the benefits of 3D printing. Why is it so important to create new 3D printing materials, you might ask. New design and manufacturing techniques and even finishing techniques are making the technology go further every day. Possibilities offered by 3D printing technology are endless, and developing new 3D printing materials with new properties will help this technology develop to its full capacity.
Using new printing materials, new industries, companies, and sectors could start to be interested in additive manufacturing and improve their manufacturing process significantly. All this research is so promising, and some of your projects could soon be 3D printed with wood, with some good print quality! Wood 3D printers could be a reality sooner than expected.
