Requirements

Pre-colored requires a few steps for set-up on Shop3D:

Format Required

The model for pre-color 3D printing consists of 3 files: A model, a texture and a UV-MAP with the formats of .OBJ, .MTL and .BMP/JPEG/PNG, respectively.

The .MTL file needs to be linked to the appropriate corresponding files, so if it is assigned a .BMP, a .PNG file should not be provided.

Alternatively, you can attach a VRML/WRL file, as this contains all required materials.

Note: If you opt to upload a WRL as an attachment, please add this blank MTL file as well to avoid possible compatibility issues with Shop3D.

File Size

At the moment Shop3D only supports models under 256 Mb. Don't worry - the model weight normally can be easily decreased with decimation.

Mesh and Details

Make sure your mesh is closed, oriented and single. All details on the model (.obj)
need to have a minimum thickness of 2mm. The mesh needs to be one single model, not separated into various files as this can cause issues during the printing process.

Model Size

Shop3D full-color bed size allows you to print models in sizes up to 508 x 508 x 305mm

File Name

All files should have the same file name. No dots or other unnecessary symbols are to be included in the titles for example.

How to upload:

Begin by uploading your .OBJ file, adding the name, descriptions and images of your product as you normally would. Note: for Pre-Color models, a .STL file will not be accepted.

In order to avoid possible customer error and reduce the chances of your customers purchasing the wrong item. We highly recommend including the following disclaimer on your product's description:
"This model is Pre-Colored which means it is digitally painted and manufactured in color."

Proceed by clicking the "View Product" button once you're finished.

Click on the paper clip icon under the file's name, and upload your .MTL and texture file as attachments to the model.

Click on "Edit price", and click on the green plus icon.

Under "Material" select "Resin", and under "Color" select "Multi".

Click the green "Add" button.

Important note: make sure that you delete the Grey Resin option to give your customers accurate pricing at face value.

We recommend a 50-80% markup from the Shop3D cost to keep your color models accessible to customers.
