The STARDUST 3D range offers a series of products specifically designed for FDM or resin 3D prints, available in 60ml or 250ml sizes for enthusiasts and professionals. (Products also available in 5L and 20L upon request)

Purpose and Usage

Acrylic primers are self-leveling liquid primers designed to be sprayed with an airbrush or paint gun. They dry quickly, creating a smooth, leveled, and matte surface ready to paint.

The acrylic primer for 3D printing is specially formulated to create a covering and uniform color without hiding the micro-details of miniature figurines. Each layer deposits a dry film thickness of approximately 25µm (0.025mm).

The acrylic 3D primer is perfect for FDM/PLA or Resin 3D printed parts and possesses numerous qualities for this purpose :

• Solvent-free acrylic formula, non-flammable, odorless, non-hazardous

• Excellent multi-surface adhesion

• Excellent fluidity

• Self-leveling

• Quick drying

• Compatible/Overpaintable with all acrylic and solvent-based paints

The background color is crucial, and it should be chosen based on the paint colors and effects to be applied

White Base : fluorescent paint, vibrant colors, light pearlescent paints

Gray Base : general colors, medium tones

Black Base : recommended for metallic paints, pure pearlescent paints

Surface Preparation : Don't skip these steps!

Avant de décorer ses figurines imprimées, il convient de bien préparer le support.

Before decorating printed figurines, it's essential to properly prepare the support.

If possible, remove roughness, streaks, support points, etc., with P320 sanding. On complicated areas, it's advisable to use a gray abrasive sponge

♣ For small-sized and intricately shaped figurines, acrylic primers are perfect as they can be applied directly without sanding.

For medium and large prints (Cosplay), prefer solvent-based spray or pot primers. These products provide better coverage and filling and are meant to be sanded.
