Overview:

After printing the squirrel model, designer sand it smooth and apply color to it.

Project Introduction

When crafting with FDM 3D printer, designers sometimes feel that they are bound by the materials. Currently, FDM 3D printer mainly uses thermoplastic as the raw materials, as well as the surface texture. However, with post process, the printed model can be more colorful and even has a metal texture.

Print the model

For this project, we use a squirrel model as an example. After sliced by 3DStar software, the model was saved in a USB drive and loaded into the Einstart-C 3D printer. Couple hours later, a beautiful squirrel was printed and ready for post process.

Polish the Surface

Surface polish is necessary for later coloring. Using a fine sand paper to smooth the surface.

Coloring

Acrylic paint was used for coloring in this model as it has a strong bond with the PLA model surface. To paint the model, the first step is to apply a black base. Use black acrylic paint to cover the whole model evenly.

Wait for the base paint to dry and then apply bronze paint. Dry up the bronze paint a little bit before painting onto the model. This will prevent the paint from flowing into detailed place and destroying the texture. Gently brush the surface so that the paint only apply to the protruding area.

Finally, apply varnish paint to make the surface shining and create a metal reflective effect. Also, varnish can protect other paint layers.

With post process, it is possible to use a low-cost desktop 3D printer to create wonderful art with different textures.
