To start 3D printing or Laser Cutting, you'll need to create an account here. Once done, you'll be able to upload your files and get live quotes of yours parts

Sculptris lacks features that are available in more advanced programs, such as its counterpart ZBrush. This software is unable to do any analyzing, measuring or resizing of your model.
To actually perform these actions, you can use Blender. Just export your file as a .obj and import it into Blender. For more information on using Blender for 3D printing, please see our tutorial Prepare your file for 3D printing with Blender.
To export the texture (not as a 3D model of the component but as a separate entity, or “parent”), activate the “Show Advanced Tools” button and then export the texture with “Save Texmap.”
Export this texture in the format “PNG” in a specific folder. In our case, we will save the texture as “dino.png.”
Then we’ll save the “model” which is simply the 3D shape. To do this, click on the “Export” button. Then save it in the same folder with the same name.
Now, on to the creation of the .mlt file. This file will serve as a connection between the texture and your 3D model. In other words, in the absence of this file, the computer will not know where to apply the texture (.png) to the 3D model (in .obj).
First, go to the folder that contains the dino.png and dino.obj. Open the document “dino.obj” in a text editor like this:
Then add on top of the text the following two lines of code:
Then delete the line “usemtl (null)”
That will give you this:
Then replace the first line “MA_MODEL” with the name that you used to name your file. In our case, we therefore “dino”. Once this is done, close the file.
Create a new text document will maintain the same name throughout the process. For us, it will be “dino.txt.” This will serve as our .mlt file, eventually.
Open the text file and then copy the following lines: newmtl material_0 map Kd MY TEXTURE.png. Then, replace “MY TEXTURE” with the name you use. So in our case, substitute “dino”.
Last step, change the extension from txt file to “.mlt.” After setting up your operating system to display the extensions, simply change the endings .txt .mlt like this:
Your MLT file is ready.
To transfer your model on our site for a print, we need to upload all 3 of these files at the same time. For this, you need to compress them into a single .zip (or compressed) file.
Once your .zip created, you just have to upload it to Sculpteo! We’ll print it for you.
