Summary

Celebrate birthdays in a stylish and personal way!
This series of heart-shaped decorations features milestone ages — 10, 18, 20, 30, … up to 90 and even 99. Each number is embedded inside a heart silhouette, optional with a second heart above the number, making it perfect as a table decoration, gift insert, or keepsake.

While these hearts can be printed on a home 3D printer in PLA or PETG, they truly shine when manufactured with professional-grade materials and finishing through JUSTWAY.

Recommended Material & Process:

Nylon (PA12) with SLS (Selective Laser Sintering): Strong, slightly flexible, and smooth — perfect for fine lettering and clean edges. Works great for everyday use and lightweight decorations.
Resin (SLA/DLP): For smaller versions with very high detail, producing crisp lines and a polished look.
Aluminum (SLM): For a premium, long-lasting decoration — perfect for milestone birthdays. Lightweight yet durable, with the option for polished or matte finishes.
