How to Clean and Maintain 3D Printed Figurines

Keeping Your Collection Looking Great

3D printed figurines are surprisingly low-maintenance, but like any display item, they benefit from occasional cleaning and thoughtful placement. A few simple habits will keep your collection looking great for years.

Dust is the primary enemy of displayed figurines. Over time, fine dust settles into the crevices and details of 3D printed pieces, dulling their appearance and obscuring the craftsmanship. Regular light dusting prevents buildup and keeps your collection vibrant.

The good news is that PLA and PETG are both stable materials that do not degrade under normal indoor conditions. Your figurines will not yellow, crack, or deteriorate simply from sitting on a shelf.

Dusting and Light Cleaning

For routine maintenance, a soft makeup brush or small paintbrush is the ideal tool. The soft bristles reach into crevices and detailed areas without scratching the surface. A quick brush-over every few weeks prevents dust from accumulating.

Compressed air cans — the same kind used for cleaning keyboards — work well for removing dust from hard-to-reach areas. Hold the can upright and use short bursts to avoid spraying propellant liquid on the figurine.

For more thorough cleaning, a slightly damp microfiber cloth can be used to wipe smooth surfaces. Use minimal moisture and dry the piece immediately afterward. Avoid submerging PLA in water for extended periods.

What to Avoid

Never use chemical cleaners, solvents, or alcohol-based products on PLA. These can damage the surface, cause discoloration, or even soften the material. Plain water with a soft cloth is all you need for the occasional deeper clean.

Avoid placing figurines in direct sunlight for extended periods. UV radiation can cause color fading over time, and the heat from direct sun exposure can potentially soften PLA on hot days. A shelf away from windows is the safest display option.

Keep figurines away from heat sources — radiators, heat vents, lamp bulbs, and other sources of concentrated heat. PLA begins to soften around 60 degrees Celsius, which can cause warping or deformation.

Storage and Moving Tips

When storing figurines that are not on display, wrap them individually in tissue paper or soft cloth. Bubble wrap works but can leave texture impressions on some surfaces if pressed too tightly.

Store packed figurines in a cool, dry location. Avoid attics and garages where temperatures can swing dramatically. A closet or shelf at room temperature is ideal.

When moving your collection, pack each piece individually and fill gaps in boxes with paper or packing material. The most vulnerable parts of figurines are thin protrusions — antennae, staffs, swords, and tails. Give these extra protection.
