Print your design with a new 3 mm wood-filament.Printable wood / LAYWOO-D3 / is a new FDM filament that I developed within the last year as an alternative printing material. It allows to print wooden-like objects with annual rings - and that without warp !The original design for my first reasonable print is a concept toy - "locomotive with plugable wheels"from the 80-ies (designed by Grit Weiss Annaberg) that I rebuilt with permission for 3D-Printing. Using the main parts asthere are easy modifications possible to create waggons for a complete train. You can print the filament in a range from 175°C to 250°C without blockage the nozzle. The flow of molten LAYWOOD3 is excellent. The printed wood will appear rough, similar to MDF Medium-Density Fiberboard Playing a little with material feed settings brings more craters or smoother surface.Annual-Rings printing-temperature: 180°C = bright colour, 245°C = dark wooden effectsfeatures of LAYWOO-D3Hygenic aspects: The composite material contains recycled wood and only such polymers that are harmless, but printed parts should not be eaten. To be honest - because the filament contains the half polymer binder - it´s not a typical bio-product and sadly not cheaper than standard ABS or PLA.your requests: I sell little trial amounts (0.25Kg) german ebay: search: printable wood / LAYWOO-D3 / trial amount January 22th 2013: 1.75 mm as a trial amount of 0.25 Kg is available in now: search in ebay please.We also found dealers in USA, Austria, Canada, Netherlands, Spain, Austria and Switzerland + Germany.
