I recently created an obj file of myself and I was using Maximo to position my character. Is there a way to save a single frame of the animation as an obj file so the model will say positioned? I am trying to save it as an obj file so I can 3D print it.
Yes there is.
the file you download will have two sets of bones... the T \ A pose you uploaded to Mixamo and the animation so you still need to use a 3D tool like Photoshop or Blender to see the correct pose anyway
also be aware the model will not have any textures when you print it out in 3D i.e, only a white \ gray model is what you finish up with but you can still paint that by hand
At AdobeMAX, they showcased some options for printing 3D that included colored sandstone. If it's a one-off that you want to send to a service like SHAPEWAYS, you can get metal, SLS, (standard PLA or ABS).
My coworkers print all kinds of solid color PLA models - some of them look great as a single color!
