View on PolymakerWhat Makes a Good Lithophane Filament?
Not all white PLA is created equal when it comes to lithophanes. The ideal filament needs specific properties that most general-purpose filaments simply don't optimize for. Understanding these factors will help you pick the perfect filament.
Critical Properties
- • Consistent translucency - Even light transmission
- • Pure white color - No yellow or gray tint
- • No impurities - Specks ruin lithophanes
- • Tight diameter tolerance - ±0.02mm or better
- • Low moisture absorption - Stays dry longer
What to Avoid
- • Off-white or warm-tinted whites
- • Inconsistent spool-to-spool color
- • Filament with visible specks or debris
- • Overly opaque "super white" formulas
- • Brittle or moisture-damaged filament

Top 5 PLA Filaments for Lithophanes - Detailed Reviews
1. Polymaker PolyLite True White PLA
Polymaker's PolyLite True White has become the gold standard for lithophane printing. The exceptional consistency batch-to-batch means every lithophane looks identical, crucial for making matching sets as gifts. The formula produces perfect translucency - not too opaque, not too transparent - creating that ideal balance where thin areas glow brightly while thick sections remain appropriately dark.
2. American Filament Lithophane Maker PLA
As the name suggests, this filament was literally designed for lithophanes. American Filament spent significant R&D optimizing the light transmission properties specifically for photo prints. The result is noticeably smoother gradients and better detail in midtones compared to standard white PLAs. It's the only filament here that lists "lithophane printing" as its primary use case.
3. eSUN PLA+ White
eSUN's PLA+ offers exceptional value for lithophane makers on a budget. The enhanced formula includes modified impact modifiers that reduce brittleness without sacrificing translucency. While not quite as consistent as premium options, the white color is true and clean with minimal batch variation. The included resealable bag helps keep moisture out.
4. Hatchbox White PLA
Hatchbox has earned its reputation as the most reliable brand in budget-friendly PLA. Their white works admirably for lithophanes with consistent quality spool-to-spool. It's the "safe choice" that won't let you down, even if it doesn't excel in any single metric. The strict quality control means fewer failed prints and wasted time troubleshooting.
5. SUNLU White PLA
SUNLU shines when you need multiple rolls at the lowest cost per kilogram. Their multi-pack deals bring the per-spool price down significantly, making them ideal for high-volume lithophane makers or sellers at craft fairs. Quality is good though slightly less consistent than premium brands. Perfect for beginners learning the craft.

Optimal Print Settings for Lithophanes
Having the right filament is only half the battle. These are the optimal slicer settings I've dialed in for consistently stunning lithophanes:
Recommended Lithophane Print Settings
Pro Tips for Better Lithophanes
Print Vertical, Not Flat
Always print lithophanes standing on edge. This ensures each layer represents a horizontal line of the image for maximum detail and proper light transmission.
Use "Positive" Mode
In your lithophane generator, select "positive" mode so thicker areas appear darker. This creates natural-looking images when backlit from behind.
Keep Filament Dry
Moisture in filament creates bubbles that scatter light unpredictably. Store your white PLA in a sealed container with desiccant for best results.
Test Your Filament First
Print a small test lithophane before committing to large projects. This lets you fine-tune settings for your specific filament batch and printer combination.
Frequently Asked Questions
What is the best color filament for lithophanes?
Pure white or "true white" PLA is the best color for lithophanes. White allows light to pass through evenly, creating proper contrast. Avoid off-white or tinted whites as they give unwanted color casts to your images. Some makers experiment with translucent/natural PLA for artistic effects.
What layer height should I use for lithophanes?
Use a layer height between 0.1mm and 0.16mm for best results. A 0.12mm layer height offers an excellent balance between quality and print time. Lower heights (0.08mm) produce smoother gradients but take much longer. Never exceed 0.2mm as you'll lose significant image detail.
Should lithophanes be printed vertically or flat?
Always print lithophanes vertically (standing on edge). Vertical printing ensures each layer represents a horizontal line of the image with consistent light transmission. Flat printing creates visible layer lines that interfere with the image and reduces contrast.
What infill percentage works best for lithophanes?
Use 100% infill - this is mandatory for lithophanes. Any gaps or infill patterns will show through when backlit and ruin the image. Enable "monotonic" infill if your slicer supports it for the smoothest surface finish.
What print speed is recommended for lithophanes?
Print slowly at 30-50mm/s for best quality. Slower speeds produce smoother surfaces and more accurate light gradients. External perimeters should be even slower at 20-30mm/s to maximize surface quality on the visible face.
Final Verdict: Which Filament Should You Buy?
For most makers, Polymaker PolyLite True White PLA is the clear winner. The consistent quality, perfect translucency, and reliable results justify the modest price premium. You'll waste less filament on failed prints and produce more impressive lithophanes.
If you're on a tight budget or just starting out with lithophanes, eSUN PLA+ White delivers solid results without breaking the bank. It's forgiving enough for beginners while still producing beautiful gift-worthy prints.
For high-volume makers selling at craft fairs or online, SUNLU multi-packs offer unbeatable cost per print while maintaining acceptable quality for commercial work.
