Application

Glow-in-the-dark materials for 3D printing

Additive manufacturing places its own demands on pigments – from filament compatibility to stability in the printing process.

Technology

Technical key points

  • Filament and resin systems

    For filaments, the pigment is compounded into the polymer; for DLP and SLA resins, it is stirred into the liquid resin. In resins, as with casting resins, keep an eye on settling.

  • Heat resistance during printing

    The glow pigment is stable up to 1,100–1,200 °C. Tinted pigments should not be used from approx. 150 °C – for filaments, untinted pigments with a light, whitish daylight colour are therefore the right choice, such as yellow-green and blue-green.

  • Particle size, print quality and brightness

    Finer grades are easier to process and give smoother surfaces but glow somewhat less. We match the particle size to your printing process.

Raw materials

Suitable raw materials & processing

We supply the glowing building block – you process it further. For 3D Printing, these raw materials are suitable:

  • Six piles of photoluminescent pigment powder in green, aqua, blue, violet, orange and red, glowing in the dark

    Pigments

    Compounding into filament or stirring into DLP and SLA resins.

In practice

Typical use cases

  • Prototypes with an afterglow function
  • Customised consumer goods
  • Printed functional parts for safety marking

Material

Material data at a glance

Key data of our glow pigments. How brightly a product glows in the end depends on carrier, layer thickness, loading and excitation – which is why we clarify this together through sampling in your own system.

Strontium aluminate glow pigments
MaterialEuropium/dysprosium-doped strontium aluminate, inorganic
SurfaceSiO₂-coated and therefore hydrolysis-resistant – even permanently in water
Thermal stabilityGlow pigment 1,100–1,200 °C; from approx. 150 °C use only untinted pigments (light, whitish daylight colour)
Glow coloursYellow-green (base shade, brightest), blue-green, blue; further shades tinted and weaker
Afterglow durationYellow-green, blue-green, blue: more than 10 hours in total darkness, as a faint glow after 1–2 hours
ExcitationUV content (daylight, UV from 365 nm) charges fastest, artificial light more slowly
Guide loading15–20 % relative to the carrier material, 30–50 % in opaque carriers
Ageingaround 5 % loss of brightness over 10 years (empirical value)
