3D Printed Lithophanes: A Step-by-Step Gift Making Guide

Introduction

If you own a 3D printer, you’ve probably heard about lithophanes. They’re one of those projects that seem complicated until you actually try one. A lithophane is essentially a 3D printed picture that shows up when you hold it up to light. Where the print is thin, light comes through. Where it’s thick, it stays dark. The whole thing turns into a grayscale photograph. It sounds like a lot, but once you get the hang of it, it’s one of the more rewarding things you can make on a printer. This guide covers How to Make to make 3d printed lithophanes from scratch—image choice, software settings, and the little printer tweaks that make the difference between something you’ll give as a gift and something you’ll toss.

I spent way too long figuring this out the hard way. Here’s what I wish I’d known from the start.. For more on this, see our guide on How to Build a 3D Printed Drone: Materials and Setup Guide.

I’ve printed dozens of these over the last few years. Some came out great. A few got thrown out. The difference was almost always a handful of decisions I made before hitting print. This should help you avoid the bad ones and get to the good ones faster.

What Is a Lithophane? A Quick Overview for Beginners

A lithophane is basically a carved relief in a thin sheet of material. You hold it up to light, and the different thicknesses create a photographic image. Dark spots are thick plastic that blocks light. Light spots are thin and let it through. The result is a surprisingly detailed black-and-white version of your original photo.

This isn’t a new idea. People have been making lithophanes from porcelain and wax since the 1800s. But 3D printing makes it doable for anyone with a basic FDM printer and some white PLA filament.

One thing I hear a lot is that you need a resin printer for these. You don’t. A well-calibrated FDM printer with a small nozzle can produce results that are just as good for most uses. Another common idea is that lithophanes are fragile. When printed with 100% infill and the right settings, they’re pretty sturdy.

The main tradeoff is time. A decent-sized lithophane can take four to eight hours to print. It’s not a quick project, but the result is usually worth the wait.

What You Need: Essential Tools and Materials

Before you start, get these together. None of them are expensive or hard to find, but skipping any one can cause headaches.

Hardware

• A 3D printer – Any FDM printer that can do 0.1mm layer height will work. I’ve used both an Ender 3 and a Prusa MK3S for lithophanes. The Prusa is easier to dial in, but the Ender 3 can give identical results with proper calibration. If you’re after a solid starting point, a machine like the Ender 3 or similar FDM printer is a good bet.
• White filament – Standard white PLA is the best place to start. Don’t use colored or transparent filament. White gives the most even light diffusion. I’ve had good luck with eSun or Hatchbox white PLA.
• A backlight source – This could be a window, a phone screen, or a dedicated LED panel. For gifts, a simple USB LED light panel or a custom 3D printed frame with built-in LEDs works well.

Software

• A lithophane converter – The easiest one to start with is ItsLitho (web-based or app). Other good options are Lithophane Maker and 3dp Rocks. All are free or have free tiers.
• A slicer – Cura or PrusaSlicer. Both handle lithophane profiles well.

Post-Processing Tools

• Flush cutters – For cleaning up brims and stringing. If you don’t already have a pair, a basic set of flush cutters for 3D printing will do the job.
• Fine sandpaper (400-600 grit) – Optional if you want a smoother finish.
• Clear coat spray – Optional for protection and a bit of polish.

Choosing the Right Image: Tips for Success

The image you pick is the single most important factor in how your lithophane turns out. A bad photo will give you a bad lithophane no matter how well you tune your printer settings.

What makes a good image?

• High contrast – You want clear differences between light and dark. Portraits with strong natural lighting work great.
• Well-lit subject – Avoid shadows across faces or harsh backlighting.
• Minimal background noise – A plain background helps the subject stand out. Busy backgrounds create muddiness in the final print.
• Faces – People and pets with distinct facial features produce the best results. Landscapes and text-heavy images can work but are less predictable.

I once tried a group photo taken in a dimly lit restaurant. The print looked like a blurry ghost. Too much noise, not enough contrast. I should have known better. Straight into the scrap pile.

Stick with simple, high-resolution portraits for the first few tries. You can get more creative once you see how the software handles different image qualities.

Converting Your Photo: A Step-by-Step Guide to Using Lithophane Software

For this guide, I’ll use ItsLitho because it’s beginner-friendly and gives reliable results with minimal tweaking. The process is similar across most converters.

Step 1: Upload Your Image

Open ItsLitho and upload your photo. The software will show a preview of how the lithophane will look backlit.

Step 2: Choose Your Shape

ItsLitho offers several shapes. For beginners, start with:

• Flat – The simplest option. Good for frames or standalone display.
• Curved – Creates a slight arc. Works as a nightlight or desk ornament.
• Cube or cylinder – More advanced but impressive results.

I’d recommend a flat or slightly curved shape for your first try.

Step 3: Adjust Settings

These settings matter:

• Thickness – 3mm to 4mm is a good range. Too thick and the dark areas are hard to see. Too thin and the print gets fragile.
• Border – A 5mm to 10mm border gives you room to handle the print without touching the image area.
• Min thickness – Leave it at the default (around 0.6mm to 0.8mm). This controls how much light passes through the lightest areas.

Step 4: Generate the STL

Click the generate button. The software will make a 3D model from your image and settings. Download the STL file.

Step 5: Import into Your Slicer

Open your slicer and load the STL. Don’t scale the model unless you have to. Scaling changes the thickness and ruins the effect.

The whole process takes less than five minutes. The time investment is small compared to the print time, so take a minute to get the settings right.

Printer Settings That Make or Break Your Lithophane

This is where most lithophanes go wrong. The default settings in your slicer aren’t meant for this kind of print. Here’s what I use for every lithophane.

Layer Height

Use 0.12mm or 0.16mm. Anything thicker and you lose detail. Finer layers give you a better grayscale gradient. A 0.12mm layer height adds about 30% more print time, but the clarity improvement is worth it.

Infill

100% infill. No exceptions. A lithophane needs to be solid to hold its shape and display the image correctly. Less than 100% leaves voids that look like print errors backlit.

Supports

No supports. Lithophanes are meant to be printed upright. Orient the model right and you don’t need supports. Adding them will damage the surface when removed.

Print Speed

Slow down. I print lithophanes at 40mm/s to 50mm/s. Higher speeds introduce vibration and layer shifting that blur the image.

Orientation

Print the lithophane standing upright on its edge. This gives the best detail because the nozzle extrudes vertically along the image features. Laying it flat on the build plate gives a much worse result.

Filament Temperature

Follow the manufacturer’s recommendation for your white PLA. For most brands, that’s 190-210°C. If you see stringing, lower it slightly. If you see poor layer adhesion, raise it slightly.

Cooling

Keep cooling at 100% after the first layer. Good cooling helps the thin layers set quickly and hold detail.

Printing Your Lithophane: What to Expect

A typical 100mm x 150mm flat lithophane at 0.12mm layer height takes about five to seven hours to print. A curved lithophane of similar size takes slightly less because the arc reduces the total height.

The first few layers are critical. Watch them go down. If the nozzle is too close to the bed, the first layer gets squished and you lose detail. If it’s too far, the print won’t stick. If you see either problem, stop and adjust your Z-offset or bed leveling.

Common failure points during the print:

• Warping – The corners lift off the bed. This happens when the bed temperature is too low or when the room is drafty. A brim helps prevent this.
• Layer separation – Thin sections delaminate. Usually caused by insufficient extrusion or poor cooling. Check your extruder calibration.
• Stringing – White PLA tends to string on lithophanes because of all the small movements. A few fine strings are normal. Heavy stringing means the temperature is too high or retraction needs tuning.

Most prints finish without major issues if you’ve calibrated recently. If you haven’t printed in a while, run a quick calibration cube first to make sure your settings are still dialed in.

Post-Processing: Smoothing and Finishing Your Lithophane

Once the print finishes, let the bed cool down completely before removing the lithophane. Warm prints are flexible and can warp if removed too early.

Step 1: Remove Brim or Raft

If you used a brim, peel it off carefully. Flush cutters work well for stubborn spots. Don’t pull hard against the surface or you might crack it.

Step 2: Clean Up Stringing

Use a heat gun on low setting for a few seconds to melt away fine strings. Be careful not to overheat the surface. A lighter works in a pinch but is harder to control. You can also gently sand off stringing with fine-grit sandpaper.

I’ve used both approaches extensively, and honestly, it depends entirely on what you’re trying to accomplish.. For more on this, see our guide on 3D Printing for Tabletop Gaming: Best Settings for D&D Minis.

Step 3: Light Sanding (Optional)

If you want a smoother front surface, lightly sand with 400-grit sandpaper. Don’t press hard. You’re only trying to remove the top layer of nozzle marks. Sanding also slightly thins the material, which affects light transmission. Keep it minimal.

Step 4: Clear Coat (Optional)

A spray-on matte clear coat gives the lithophane a finished look and protects it from dust and fingerprints. I use Krylon Matte Finish. One light coat is enough. Don’t use gloss—it creates glare that washes out the image.

Step 5: Backlight Your Lithophane

Hold it up to a window or place it on a light panel. The image will appear. If you want a permanent display, mount it in a 3D printed frame with a USB LED panel behind it.

5 Common Mistakes Beginners Make (And How to Avoid Them)

I’ve made all of these. Here’s how to skip them.

1. Using a low-contrast photo. A photo that looks fine on a phone won’t necessarily translate well. If the image has lots of mid-tones without clear highlights and shadows, the lithophane will look muddy. Choose images with clear definition between light and dark.

2. Printing at the wrong layer height. Anything above 0.2mm will give a staircase effect on curved surfaces. Stick to 0.12mm or 0.16mm for clean results.

3. Not calibrating before printing. If your extruder is over-extruding by 5%, the extra plastic thickens the thin areas and washes out highlights. Run an extrusion calibration test before your first lithophane.

4. Rushing the support decision. Adding supports to a lithophane is almost always a mistake. They leave marks that can’t be sanded away without destroying detail. Orient the print so no supports are needed.

5. Using the wrong filament. Cheap white PLA can have dyes that block light unevenly. Stick with reputable brands like eSun, Hatchbox, or Inland for consistent results.

Best Filaments for Lithophanes: Comparing Options

Not all white filaments are the same. Here’s a breakdown of what works best.

Standard White PLA

This is your best all-around option. It gives good light diffusion, prints easily, and is affordable. Most white PLA filaments are slightly translucent when thin enough, which is exactly what you need. Hatchbox White PLA and eSun White PLA are my two go-to options. If you want a reliable brand to stock up on, white PLA filament from eSun or Hatchbox is a solid choice.

Silk White PLA

Silk PLA has a glossy finish that looks nice on other prints but hurts lithophane quality. The gloss creates hotspots that make the image uneven when lit. Avoid it for lithophanes unless you really want a shiny surface and can accept some loss in clarity.

Translucent PETG

PETG is more durable and slightly more transparent than PLA. It needs higher print temperatures and better cooling. PETG lithophanes are less likely to crack if dropped, but print quality is slightly lower because PETG strings more. Use PETG only if you need extra durability, like for a keychain or outdoor use.

Specialty White Filaments

A few brands make filaments specifically for lithophanes. These are usually more expensive but can produce slightly better results. ProtoPasta White HTPLA is one example. Worth trying if you have a project that needs the best possible quality, but standard white PLA is good enough for most people.

Creative Gift Ideas Using Lithophanes

Lithophanes make excellent personalized gifts because they combine photography with something you made yourself. Here are a few ideas that are easy to do.

Nightlights. Print a curved lithophane and mount it on a small USB-powered LED base. You can find pre-made nightlight frames on Etsy or design your own in Tinkercad. These work well for grandparents who want photos of grandchildren in their kitchen.

Keychains. Use a small lithophane, about 30mm x 40mm, with a hole for a keyring. These print quickly and make good stocking stuffers. Keep the image simple. A face works better than a full-body shot at this scale.

Ornaments. Flat circular lithophanes with a hole at the top can hang on a Christmas tree. Add a festive border or a small hook. These have been some of the most appreciated gifts I’ve given.

Coasters. Print flat square lithophanes as coasters. They’re functional and a conversation starter. You’ll need to seal them with clear coat to protect against moisture. PETG is a better choice for coasters because it handles heat and moisture better than PLA.

Desk keepsakes. Small curved lithophanes on a simple stand make nice desktop decorations. I have several around my workspace showing travel photos. They’re subtle enough to not be distracting but noticeable enough to start a conversation.

Final Tips for Success: Settings, Patience, and Practice

Your first lithophane probably won’t be perfect. That’s normal. Here’s what I’ve learned after printing dozens.

Always print a small test first. Use a low-resolution photo of a face and print it at 50% scale. This takes about two hours and will reveal any problems with your settings or filament before you commit to a six-hour print. Adjust based on what you see.

Keep a log of your settings. I use a simple spreadsheet where I record the layer height, filament brand, temperature, and print orientation for each lithophane. This helps me replicate good results and avoid repeating bad ones.

Don’t get discouraged by early failures. I’ve had prints that looked fine while printing but turned out blurry backlit. I’ve had prints that warped halfway through. Each failure taught me something specific. After a few tries, you’ll have a solid feel for how your printer handles these.

Experiment with different images and shapes once you have the basics down. Flat lithophanes are easiest, but curved ones often look more polished. Cube lithophanes are tricky but produce stunning results when done right.

Frequently Asked Questions About 3D Printed Lithophanes

Can I use any filament?
Not really. Only white or light-colored filament works well. White PLA is the standard. Some off-white or beige filaments can work but give a yellow tint. Colored or dark filaments block too much light.

How long does a lithophane take to print?
A standard 100mm x 150mm lithophane at 0.12mm layer height takes about five to seven hours. Size and layer height are the biggest factors. A small keychain-sized one might take 45 minutes. A large wall display could take 12+ hours.

Why is my lithophane blurry?
Blurriness usually comes from one of three things: the original image is low resolution or low contrast, the layer height is too thick (above 0.2mm), or your printer has mechanical looseness like a loose belt or wobbly frame.

Do I need supports?
No. If you orient the lithophane upright and use a brim to keep it from falling, no supports are needed. Adding supports will damage the surface.

Can I make a color lithophane?
Full-color lithophanes require a specialized process called hueForge or similar techniques using multiple filament colors or color mixing. It’s much more complex than a standard single-color lithophane. For most people, the grayscale result is satisfying enough.

How do I clean the print surface after printing?
Isopropyl alcohol and a microfiber cloth work well. Avoid acetone or harsh solvents that can damage PLA. If you applied clear coat, use a damp cloth.

Ready to Print Your First Lithophane?

By now, you have everything you need to make a solid first lithophane. Grab a good high-contrast photo, some quality white PLA, and a few hours of printer time. Use the settings and tips in this guide, and you’ll end up with something worth giving as a gift or displaying on your own desk.

After all the research and comparison, I’ve found that the simplest answer is usually the right one.

If you want to get started quickly, grab a spool of Hatchbox or eSun white PLA and visit ItsLitho to convert your first photo. The software is free, and the printing is straightforward once you know what to look for. Start small, note your settings, and don’t be afraid to try again if the first print isn’t perfect..
