You have invested in a collection of 3D printed figurines, and you want them to look as good in five years as they do today. The good news is that PLA and PETG collectibles are inherently durable and require minimal maintenance. The less good news is that a few common mistakes, such as leaving a figurine on a sunny windowsill or using the wrong cleaning products, can cause permanent damage that is difficult or impossible to reverse.
This guide covers everything you need to know about caring for your 3D printed collectibles, from daily handling to long-term storage, cleaning techniques, UV protection, and even basic repair methods for the occasional accident.
At 3DCentral, we produce over 4,300 unique collectible designs at our facility in Laval, Quebec, using primarily PLA and expanding into PETG. We have tested our products under a wide range of conditions and gathered care recommendations from thousands of customers. This guide distils that knowledge into practical, actionable advice.
Understanding Your Figurine’s Material
Before you can properly care for a 3D printed figurine, you need to understand what it is made from. The material determines how the piece responds to heat, light, moisture, and handling. For a detailed material comparison, see our PLA vs PETG material guide.
PLA (Polylactic Acid)
The most common material for 3D printed collectibles. PLA is rigid, produces fine detail, and comes in an enormous range of colours. Key care considerations:
- Softening point: approximately 60 degrees Celsius — vulnerable to heat sources
- UV sensitivity: colours fade over months of direct sunlight exposure
- Moisture resistance: good for indoor use; prolonged water exposure is not recommended
- Brittleness: rigid but can crack or chip on hard impacts
PETG (Polyethylene Terephthalate Glycol)
PETG is tougher, more flexible, and more heat-resistant than PLA. It is increasingly used for outdoor display pieces and frequently handled collectibles. Key care considerations:
- Softening point: approximately 80 degrees Celsius — significantly more heat-resistant
- UV resistance: substantially better than PLA; maintains colour longer in sunlight
- Impact resistance: more likely to flex than crack when dropped
- Surface: slightly glossier, can show fingerprints more readily
Daily Care and Handling
Handling Your Figurines
The simplest care advice is often the most overlooked: handle your figurines with clean, dry hands. Skin oils transfer to the surface of the print, and over time these oils attract dust particles that settle into the layer lines that characterise FDM-printed objects. On lighter-coloured prints, particularly white, cream, and pastel shades, accumulated skin oil creates a visible yellowing or dulling effect.
For particularly valuable or delicate pieces, such as detailed busts or large fantasy display pieces, consider wearing cotton gloves when repositioning them. This is standard practice in traditional figurine collecting and applies equally to 3D printed collectibles.
Handling Articulated Figurines
Articulated figurines with print-in-place joints, such as those designed by Flexi Factory and Cinderwing3D, require a specific handling consideration: work the joints gently when the piece is new. Fresh off the build plate, joints may feel slightly stiff as thin connection points between segments settle. Flex each joint through its full range of motion a few times with gentle pressure. Forcing a stiff joint aggressively can snap the connection point.
Once broken in, articulated joints should move smoothly. If a joint becomes stiff over time (usually from accumulated dust), a quick pass with compressed air into the joint gap restores free movement.
Cleaning Your 3D Printed Figurines
Routine Dusting
Dust is the primary enemy of displayed 3D printed figurines. The layer lines inherent to FDM printing create tiny horizontal ridges that trap dust particles. Regular dusting prevents buildup that becomes progressively harder to remove.
Recommended tools:
- Soft-bristle brush: a clean makeup brush or dedicated display brush works perfectly. Natural bristles are gentler than synthetic on delicate features.
- Compressed air: a can of compressed air or a small electric air blower removes dust from crevices, joints, and fine details that a brush cannot reach. This is especially useful for articulated pieces where dust settles between joint segments.
- Microfibre cloth: for larger, smoother surfaces like the base of gnomes or the body of ducks, a dry microfibre cloth lifts dust effectively.
Dust weekly if your figures are displayed in the open. Monthly if they are in enclosed display cases.
Deep Cleaning
When dusting alone is not sufficient, a gentle wet clean restores the original appearance.
Method:
- Fill a bowl with lukewarm water (never hot — PLA softens at 60 degrees Celsius).
- Add a tiny amount of mild dish soap, just enough to create a slight lather.
- Dip a soft cloth or soft toothbrush into the soapy water and gently clean the figurine’s surface.
- For stubborn grime in layer lines, a soft-bristle toothbrush works well. Brush along the layer lines, not against them.
- Rinse by wiping with a cloth dampened in clean water.
- Dry thoroughly with a clean microfibre cloth. Do not leave wet — standing water in layer lines can attract dust more quickly.
Products to avoid:
- Rubbing alcohol (isopropyl) — can cloud PLA surfaces, especially on glossy or silk finishes
- Acetone — dissolves and warps PLA; it is a smoothing agent for ABS, not PLA
- Bleach or harsh chemical cleaners — can discolour and weaken the plastic
- Abrasive cleaners or rough sponges — will scratch the surface
- Hot water — temperatures above 50 degrees Celsius risk deforming PLA
Cleaning PETG Figurines
PETG is more chemically resistant than PLA, so cleaning is slightly easier. The same lukewarm water and mild soap method works, but PETG tolerates slightly warmer water (up to 65 degrees Celsius) and is less prone to cloudiness from brief alcohol exposure. Still, the safest approach is mild soap and water for both materials.
Protecting from Heat and Sunlight
The Heat Danger Zone
Heat damage is the number one cause of ruined 3D printed figurines. PLA begins to soften at approximately 60 degrees Celsius, a temperature that is surprisingly easy to reach in everyday situations:
- Sunny windowsill in summer: surface temperatures can exceed 65 degrees Celsius
- Car dashboard or enclosed car interior: routinely exceeds 70 degrees Celsius
- Near a heat vent or radiator: direct warm airflow can push surface temperature past the softening point
- Top shelf near ceiling in a warm room: heat rises, and the top of a tall bookshelf can be 5-10 degrees warmer than floor level
Heat-damaged PLA warps gradually. A figurine may lean slightly, a base may bow, or thin features like wings or weapons may droop. This damage is essentially irreversible because the material has physically deformed.
Prevention: Display PLA figurines at least one metre from any heat source. Avoid direct sunlight positions entirely. If you want figurines in a sunny room, choose a shaded shelf or display case. For sun-exposed positions, PETG pieces are a safer choice.
UV Protection
Ultraviolet light degrades PLA over time, causing colour fading and surface chalking. This process is gradual — months rather than days — but cumulative and irreversible. Dark colours (black, navy, dark green) are most resistant to fading. Light and bright colours (white, yellow, bright pink) fade fastest.
Protection strategies:
- UV-filtering display cases: glass or acrylic cases with UV-protective coating block the harmful wavelengths while allowing visible light through
- UV-filtering window film: applied to windows, this reduces UV penetration into the entire room and protects all displayed items
- Position management: display figurines on shelves that do not receive direct beam sunlight, even if the room is bright overall
- Rotation: periodically rotate figurines to distribute any UV exposure evenly across all surfaces
Optimal Display Conditions
Temperature
The ideal temperature range for displaying PLA figurines is 15-25 degrees Celsius, which conveniently matches normal indoor living conditions in most Canadian homes. Temperature stability matters more than absolute temperature; rapid fluctuations can cause micro-stresses in the material.
Humidity
PLA is mildly hygroscopic, meaning it can absorb moisture from the air. In display conditions, this is rarely a practical concern. However, in high-humidity environments (bathrooms, unconditioned basements, outdoor covered porches), prolonged exposure can cause slight surface haziness. For most Canadian indoor environments, humidity is not a factor.
Display Surface
Place figurines on stable, level surfaces. Some PLA colours can leave faint marks on certain finishes over time (particularly soft-painted wood or certain plastics), so felt or fabric pads beneath figurines protect both the piece and the surface.
Repairing Damaged Figurines
Broken Pieces
If a figurine breaks cleanly (a snapped wing, broken antenna, or separated base), super glue (cyanoacrylate) bonds PLA effectively. Apply a thin layer to one surface, press the pieces together firmly, and hold for 30-60 seconds. Wipe any excess immediately with a dry cloth.
For structural repairs where strength matters, two-part epoxy provides a stronger bond than super glue, though it requires mixing and longer curing time (typically 5-10 minutes working time, 24 hours to full strength).
Scratches and Surface Damage
Light surface scratches on PLA can sometimes be reduced by gently rubbing with a fingernail or the back of a spoon (applying warmth through friction softens the very top layer enough to reduce the scratch). For deeper scratches, light sanding with 800-1200 grit sandpaper followed by a clear coat spray can restore the surface. This approach works best on single-colour pieces.
Heat-Warped Figurines
Minor heat warping can sometimes be corrected by carefully warming the affected area to just above PLA’s softening point (using a heat gun on low, held at a distance) and gently bending the piece back into shape, then immediately cooling with a blast of compressed air or cold water. This is delicate work with a risk of further damage, so only attempt it on pieces you are prepared to potentially lose.
Colour Fading
UV-faded colours cannot be restored to their original vibrancy. The degradation is chemical, not surface-level. However, faded figurines can be repainted with acrylic paint to give them new life. Many collectors enjoy the creative aspect of repainting as an opportunity to customise their pieces.
Long-Term Storage
If you need to store figurines (seasonal rotation, moving house, collection overflow), proper storage prevents damage during non-display periods.
Individual Wrapping
Wrap each figurine individually in tissue paper or bubble wrap. Avoid newspaper, which can transfer ink. For articulated figurines, gently straighten the joints to their neutral position before wrapping to avoid stress on the joint mechanisms.
Box Storage
Store wrapped figurines in cardboard boxes with dividers between pieces. Avoid stacking heavy items on top. Label boxes clearly so you can locate specific pieces without opening every box.
Environment
Store in a climate-controlled space. Avoid attics (temperature extremes), unconditioned garages (temperature and humidity swings), and damp basements. A bedroom closet or climate-controlled storage unit is ideal.
Caring for Specific Product Categories
Ducks
3D printed ducks are typically sturdy with simple geometries, making them among the easiest collectibles to maintain. Their rounded shapes resist dust accumulation better than detailed figurines. A quick wipe with a dry microfibre cloth keeps them looking fresh. For ducks displayed on car dashboards (popular in Jeep ducking culture), use PETG versions to withstand the heat.
Gnomes
Gnome figurines often feature fine details like beards, hats, and small accessories that trap dust. A soft brush is more effective than a cloth for cleaning beards and textured surfaces. For outdoor garden gnomes, PETG versions resist UV and weather better than PLA. Bring PLA gnomes indoors during extreme weather.
Articulated Figurines
Articulated pieces from artists like Flexi Factory and Cinderwing3D need periodic joint maintenance. Use compressed air to clear dust from joint gaps every few weeks. If joints become sticky, a tiny drop of silicone lubricant (NOT WD-40, which can damage plastic) on a toothpick applied to the joint restores smooth movement.
Busts and Large Display Pieces
Larger busts and fantasy display pieces have more surface area exposed to dust and UV. Enclosed display cases are highly recommended for these premium pieces. The investment in a good display case pays for itself in reduced cleaning time and UV protection.
Seasonal Collectibles
Seasonal pieces spend part of the year in storage. Follow the long-term storage guidelines above when rotating seasonal collections. Inspect each piece when it comes out of storage: check for warping, dust accumulation in packaging, and joint function on articulated models before putting them on display.
Building a Care Kit
Assemble a simple care kit for your collection. Everything you need is inexpensive and readily available:
- Two or three soft-bristle brushes (different sizes for different figurines)
- A can of compressed air or a small electric blower
- Several microfibre cloths
- Mild dish soap
- Super glue (cyanoacrylate) for emergency repairs
- Optional: cotton gloves for handling premium pieces
- Optional: silicone lubricant pen for articulated joint maintenance
Total cost for this kit is under $25, and it will serve your entire collection for years.
Frequently Asked Questions
Can I wash 3D printed figurines in water?
Yes, using lukewarm water (never hot) with a tiny amount of mild dish soap. Gently clean with a soft cloth or soft-bristle toothbrush. Rinse with a damp cloth and dry thoroughly with a microfibre cloth. Avoid submerging articulated figurines for extended periods as water can be difficult to fully remove from joint mechanisms.
Will 3D printed figurines melt in a hot car?
PLA figurines can warp in a hot car, as interior temperatures routinely exceed PLA’s softening point of 60 degrees Celsius during summer. PETG pieces are more resistant (softening around 80 degrees Celsius) but can still be affected in extreme heat. If displaying figurines in a vehicle, PETG is the safer material choice.
How do I remove dust from articulated figurine joints?
Use compressed air directed into the joint gaps. Short bursts are more effective than sustained blasts. For persistent debris, a wooden toothpick can gently dislodge particles from between segments. Avoid metal tools that could scratch the joint surfaces.
Can I use rubbing alcohol to clean 3D printed figurines?
Avoid isopropyl alcohol on PLA, as it can cloud the surface, especially on glossy and silk finishes. PETG tolerates brief alcohol exposure better, but mild soap and water is the safest cleaning method for both materials.
How should I store 3D printed figurines when not on display?
Wrap each piece individually in tissue paper or bubble wrap. Store in a cardboard box with dividers in a climate-controlled space. Avoid attics, unheated garages, and damp basements. Straighten articulated joints to their neutral position before wrapping.
Can I repaint a faded 3D printed figurine?
Absolutely. PLA accepts acrylic paint very well. Lightly sand the surface with fine-grit sandpaper (400-600 grit), apply a primer coat, then paint with acrylics. Finish with a clear coat spray for protection. Many collectors enjoy repainting as a creative customisation opportunity.
How long do 3D printed figurines last?
With proper indoor care (away from heat and direct sunlight), PLA and PETG figurines last indefinitely. The materials do not degrade under normal room conditions. Colour vibrancy can diminish over years of UV exposure, but structural integrity remains intact. Well-maintained 3D printed collectibles can be enjoyed for decades.
