    XYZprinting has a good deal today, buy 12 rolls of filament and you receive a free DaVinci 1.0 printer.
    That is a decent printer with 7.8" cubed volume.

    Hi Adam, I am measuring your wall thicknesses...

    Hi Adam,

    I am measuring your wall thicknesses at 0.02 mm. That is impossible to 3D print with current machines.
    If you are using an FDM machine, take your nozzle size+0.05 mm for the minimum wall...

    Yes, this is no new knowledge at all. Brush-on smoothening has been proven to work and is so simple as a principle it needs no fancy abbreviation.
    Besides, CMF already stands for...

    Lowering the layer height and temperature will produce better arches.
    Also for the specific height at the top of the arches you can lower printing speeds for more consistent extrusion in those...

    Unless the part is used in water or very moist environments, I advise nylon. As an amorphous polymer, TPU with its lower hardness will display much more fatigue over time and fail due to stress...

    It doesn't work for all filaments, but setting the temperature at the lower end of the permitted range, say 195C for PLA, with the right amount of cooling, will improve these parts as well.
    But...

    Shapeways can be pretty cost-effective for small parts, study the design guidelines and optimize the file accordingly for a much nicer price!

    I participated - good survey.

    The Mechanics of Materials group at Eindhoven University is starting a PhD on food printing as well.
    It would be good to connect and align visions....

    Hi, Rhino does a lot of file conversions. With 3D Studio Max you can export a mesh to IGES. I prefer Rhino.
    These computations are very intensive so you need to have a good amount of Vmem.

    Wow, this printer started at $3k market price, now it's at 17k. If they can get the price down they would reach so many customers and people would know about this great machine. Anyway, I'm curious...

    Davo,

    Can the Hyrel Engine printers also fit two extruders simultaneously for multimaterial prints, or is that restricted to the larger models?
    We are developing a multimaterial product in...

    We found that a 0.2mm clearance works perfectly for extended straight wall sections. Walls stick together but with a razor blade can be separated. We now are stepping to full color prints but the...

    After some research we found that a 0.2mm clearance works perfectly, and is the minimum for extended straight wall sections. The walls stick together but with a razor blade can be separated. We now...

    STEP and IGES are common file formats used by manufacturing facilities for years. Together with DXF they are more or less the industry standard. They describe geometry in terms of rich definitions so...

    There is a great need for better elastomeric filaments. It would be great to have a rubber filament that can be post-cured in an oven. Not only can we specify the properties of such a rubber, the...

    Hi,
    The texture is in essence a 2D image mapped onto the coordinates of the 3D mesh.
    First realize that to 3D print texture you need a very advanced 3D printer. These work with .obj or vrml files,...

    Right, I'd also go for just the gypsum which are calcium bonds and the H20 bonds will heat up in the microwave.
    I suppose you need a dedicated microwave for this because you will have large...

    Hi,

    As Marm said, plaster of Paris will be your best option based on a 3D printed mother mold.
