Finishing Touches and Post-Processing for 3D Printed Animals

Creating a 3D printed animal is only part of the journey. The magic truly comes to life in the post-processing stage, where your print transitions from a simple object to a piece of art. This phase is critical for achieving a professional look that breathes life into your model. Whether you’re working with resin or filament prints, the right finishing touches can elevate the realism and appeal of your creation.

Cleaning and Curing

For Resin Prints:
- Cleaning: Immediately after printing, resin models are covered in uncured resin, which is sticky and can obscure details. Submerging and gently agitating the model in a bath of isopropyl alcohol will remove this excess resin. A soft brush can help dislodge any stubborn spots.
- Curing: Once cleaned, curing under UV light is essential. This process hardens the resin, solidifying your model’s final form. Depending on the resin type and the size of your model, curing times can vary. A dedicated UV curing station ensures even exposure, though sunlight is a viable alternative for hobbyists.
For Filament Prints:
- Sanding: Layer lines are a common characteristic of FDM prints. Starting with a coarse grit sandpaper and working your way up to a finer grit can smooth out these lines, preparing your model for painting. For intricate details, consider using tools like needle files or sanding twigs.
- Support Removal: Supports are often necessary to print overhangs or undercuts but leave marks when removed. Carefully cutting away supports and smoothing the affected areas integrates these sections seamlessly into the rest of your model.

Painting and Detailing

The transformation of your 3D printed animal model is most dramatic during the painting and detailing stage. This is where your creative vision comes into play, adding color, texture, and life to your print.

Priming: Applying a primer is the first step in the painting process. Primer helps paint adhere to the model and can also highlight any areas that may need additional sanding. For best results, choose a primer that is compatible with both your model material and the acrylic paints you’ll be using.
Painting: Acrylic paints are widely recommended for both resin and filament prints due to their ease of use, fast drying times, and water solubility. When painting, start with broader base coats, working up to finer details with each layer. Thinning your paints can help maintain the intricacies of your model without clogging up fine lines and textures.
Detailing: This is where your model truly comes to life. Adding small details like eyes, fur textures, or specific markings can dramatically increase realism. Fine brushes, micro pens, or even a toothpick can be used for the minutest details. Consider using gloss varnish on eyes or wet surfaces to simulate moisture and add depth.
