Resins for Display Miniatures
For display models that emphasize intricate details and won’t be handled often, standard or less flexible resins are a better fit. Resins like AMD-3 provide exceptional precision and capture fine details beautifully. However, these resins tend to be more brittle and are less suited for miniatures exposed to regular use. The stiffness of these resins enhances detail clarity but comes at the cost of fragility, making them perfect for static displays or collectible pieces.
Avoiding Marketing Gimmicks
When choosing resins, don’t get swayed by exaggerated claims of 8K or 12K resolution. While higher resolution may sound impressive, detail quality largely depends on the resin’s formulation and printer settings, not just marketing buzzwords.
Additional Considerations
When selecting a resin, it’s important to consider the environmental and mechanical stresses your miniatures may encounter. For models that will face regular handling, transport, or exposure to varying conditions, focusing on specific mechanical properties can significantly enhance their durability and longevity:
- Tensile Strength: This measures the resin’s ability to withstand pulling forces without breaking. Miniatures with higher tensile strength are better equipped to endure stress during gameplay or assembly, reducing the risk of snapping or cracking.
- Impact Resistance: Perhaps one of the most critical properties for miniatures, impact resistance measures a resin’s ability to absorb shocks without breaking. A high-impact resin can prevent miniatures from shattering if dropped from a table during gameplay. Durable resins like TGM-7, known for their excellent balance of toughness and flexibility, provide peace of mind for those crafting and handling miniatures regularly.
- Elongation at Break: This property indicates how much a material can stretch or flex before it breaks. A higher elongation value means the resin has some flexibility, making it less prone to brittle failures during handling or minor impacts. Tough or ABS-like resins often excel in this area, making them ideal for functional miniatures.
- Low Water Absorption: For miniatures exposed to humid environments, paints, or washes, choosing a resin with low water absorption is crucial. This characteristic helps maintain the model’s dimensional stability, preventing warping, swelling, or degradation over time. This is particularly important for outdoor settings or display pieces that might encounter variable moisture levels.

Scaling Your Miniatures for 3D Printing: Precision Matters
When it comes to miniature resin printing, selecting the right scale for your model can be crucial. While it’s not always necessary to scale miniatures, there are cases where adjusting the size may enhance their fit and function within your existing collection. Whether you’re crafting miniatures for wargaming or board games, ensuring the scale aligns with your current models can help maintain visual coherence on the tabletop.
Scaling Miniatures Down
Scaling down STL files can be an effective way to fit larger models onto your build plate, allowing you to create stunning resin miniatures without exceeding your printer’s capacity. While resizing offers flexibility, it’s crucial to approach this process carefully to avoid compromising the quality and success of your prints.
If you decide to scale down a model, it is absolutely necessary to rework the supports—and often the hollowing and drainage holes as well. When models are reduced significantly, pre-existing support structures can become too thin or fragile, leading to detachment during printing. This can result in failed prints, loss of intricate details, and wasted time and materials.
The only exception to this rule is if you’re scaling down by a very small margin—no more than 5%. Minor adjustments like these usually don’t affect the integrity of supports or hollowing, and prints can proceed without major modifications. However, any reduction beyond this threshold demands careful re-supporting, hollowing, and re-positioning of drainage holes to ensure a successful print.
Failing to properly prepare scaled-down models can lead to structural weaknesses and difficulties in the post-processing stage. By taking the time to rework and optimize your models for their new size, you can get high-quality prints that retain their original detail and durability.
Scaling Miniatures Up
Scaling up miniatures can be an excellent way to create visually striking centerpiece models or larger bosses for tabletop gaming. However, when resizing models to a larger scale, it’s crucial to approach the support structure thoughtfully to avoid potential issues.
While supports naturally thicken during scaling, this can lead to new challenges. Overly thick supports can leave noticeable marks on the model, make removal difficult, and risk damaging the surface detail. At the same time, scaling up increases the size of unsupported spans, or “bridges,” which can compromise the stability of the print.
To address these issues, it’s better to focus on increasing support density rather than relying on automatically thickened supports. Denser supports provide greater stability for larger models while minimizing the need for overly bulky structures. However, the scaled-up model should always be re-supported for the best outcome. This ensures optimal support placement, properly sized contact points, and balanced stability for successful prints.
Printer and Model Considerations
The decision to scale up a model should also account for the capabilities of your resin 3D printer. Smaller printers may struggle to accommodate larger models, requiring segmentation of the design or hollowing to reduce resin use. Conversely, larger printers can handle significant pieces but often demand careful adjustments to the model’s setup to ensure a flawless print.
Final Tips
Always compare the scaled dimensions to existing models in your collection to ensure consistency. Attention to scale and proportion enhances the visual coherence of your gaming setup, providing both aesthetic and practical benefits.
By carefully managing the scaling process, particularly with regard to support structures and density, you can produce breathtaking large-scale miniatures that serve as impressive highlights in your collection and gameplay.

Hollowing Out Models: A Smart Approach for Certain Miniatures
Hollowing out models can be a smart strategy in resin printing, particularly for larger miniatures. This technique helps save resin and reduce print time, making it especially advantageous for sizable models that would consume significant material if printed solid. However, not all 3D printed miniatures need to be hollowed out; smaller or highly detailed models may retain their quality and structure better when printed solid.
Benefits of Hollowing Models for 3D Printing
For larger miniatures, hollowing can significantly reduce resin usage, making the printing process more economical. By creating hollow versions of your models, you can significantly reduce waste. This approach is particularly beneficial for larger tabletop gaming miniatures, where the overall weight and cost of materials can impact your project budget.
Preventing the Blooming Phenomenon
A major advantage of hollowing is its ability to mitigate the blooming phenomenon, which occurs when internal pressure builds up in solid prints during curing. This pressure can lead to surface imperfections. By hollowing your model and incorporating drainage holes, you allow excess resin to escape, reducing internal pressure and the risk of defects, ultimately improving print quality for your resin miniatures.
Addressing Suction Effects
When printing hollow models, it’s important to consider potential suction effects during the curing process. As resin cures, it can create a vacuum effect inside hollow areas, hindering adhesion to the build plate and potentially leading to warping. To combat this, add multiple drainage holes in strategic locations to equalize pressure and facilitate smooth resin flow during printing.
Tips for Hollowing Miniatures for 3D Printing
Hollowing models can save resin and improve print efficiency, but it requires careful planning to avoid common pitfalls that can lead to failed prints or trapped resin. Here are some essential tips to ensure successful hollowing:
- Optimal Wall Thickness
Aim for wall thicknesses of 2–3 mm when hollowing your model. This strikes a balance between maintaining structural integrity and reducing material usage. For smaller or highly intricate miniatures, consider leaving the model solid to avoid complications such as fragile walls or resin traps. - Avoid Closed Pockets
Carefully inspect your hollowed design for closed pockets—isolated hollow areas that aren’t connected to the main internal cavity. These can trap resin, leading to uncured sections inside your model, increasing weight, and risking long-term resin leakage. For small miniatures, hollowing may not be practical as it can unintentionally create such pockets. - Drainage Holes
Include at least two drainage holes to allow the resin to flow out during and after printing. Holes should be at least 3 mm in diameter for optimal drainage. Place them as close to the build plate as possible to ensure proper flow. Avoid positioning drainage holes where they will be heavily obscured by supports, as this can hinder their effectiveness. - Resin Flow and Cleanup
After printing, thoroughly rinse hollowed models to remove any residual resin inside. Properly placed drainage holes simplify this process, reducing the risk of clogs or leftover uncured resin.
Hollowing Miniatures: Summary
Hollowing is a powerful technique to save material and enhance print quality, but it requires attention to detail. Always review your design to eliminate closed pockets, strategically place drainage holes, and ensure proper wall thickness. This thoughtful preparation will help you produce flawless resin miniatures that are lightweight, durable, and ready for tabletop gaming or display.
Optimizing Layer Height, Exposure Times, and Supports for 3D Miniature Printing
When it comes to resin printing intricate tabletop miniatures, the interplay between layer height, exposure times, and support strategies can significantly impact your miniature quality. Each element plays a critical role in determining the quality, detail, and structural integrity of your prints. Striking the right balance between precision and efficiency is essential for producing miniatures that not only look stunning but also hold up well in gameplay or display.
Best Layer Height for Miniatures: Considerations
The layer height you choose is a critical factor in 3D printing miniatures. It determines how smooth your prints look and how visible the layer lines are. Using a smaller layer height—typically 20 to 50 microns—can significantly reduce these lines, creating cleaner and more professional-looking miniatures. This is especially important for detailed or display models.
Impact of Layer Height on Miniatures
The difference between prints at 100 microns and 50 microns is dramatic. At 100 microns, layer lines are much more noticeable, especially on curved surfaces. In contrast, 50 microns delivers sharper details and smoother finishes with less visible stepping. This improvement reduces the need for post-processing, such as sanding or excessive priming.
However, reducing layer height even further—to 20 microns—offers only marginal improvements. The finer lines may not be noticeable without close inspection, but printing times increase significantly. For most 3D-printed miniatures, the balance between quality and efficiency makes 50 microns a popular choice.
Key Considerations
- Layer Line Visibility: Smaller layer heights focus more on reducing layer line visibility than increasing detail.
- Purpose of the Miniature: Choose 20–30 microns for display pieces where a flawless finish is essential. For gaming pieces, 50 microns is sufficient and saves time.
- Time vs. Quality: Hobbyists printing multiple models may prefer higher layer heights for faster results. Those prioritizing exceptional finishes should invest in lower settings.
Finding the Balance
Selecting the best layer height for 3D printing miniatures depends on your goals. If you value speed, higher settings are more practical. For highly detailed, painted, or display miniatures, lower layer heights are worth the extra print time. Experimenting with different settings helps you find the perfect balance for your needs, ensuring your miniatures look their best while meeting your deadlines.
Best Exposure Times for 3D Printing Miniatures
Finding the optimal exposure time for resin printing is crucial to achieving high-quality miniatures with sharp details. Proper exposure settings strike a delicate balance: too short an exposure can lead to incomplete curing, resulting in weak layers and print failures, while excessive exposure may cause over-curing, blurring fine details and compromising the structural integrity of your miniatures.
To navigate this balance effectively, we highly recommend utilizing the AmeraLabs Town calibration part. This tool allows you to determine the ideal exposure settings tailored to your specific resin type, including flexible and durable options like TGM-7.

Correctly orienting your STL file is critical to achieving high-quality results in resin 3D printing. Proper model orientation not only reduces the risk of print failures but also preserves the intricate details that make 3D printing miniatures so appealing. Here’s a deeper dive into why orientation matters, how to optimize it, and what to watch out for during the process.
The Problem with Flat Orientations
Printing a model flat on the build plate can seem straightforward but often leads to significant challenges:
- Sharp Cross-Section Transitions: Large, flat surfaces can cause abrupt increases in cross-sectional area between layers. This sudden change generates higher separation forces during printing, increasing the likelihood of detachment from the build plate.
- Surface Imperfections: Flat orientations may leave visible layer lines or adhesion marks, particularly on the bottom-facing surfaces.
- Suction Effects: Flat surfaces create suction as resin cures between the model and the FEP film, which can damage the print or strain the printer’s mechanics.
Best Practices for Orienting Models
- Angle the Model:
Tilting your model slightly (30–45 degrees) during slicing can significantly improve print success. Angling reduces suction forces and promotes better resin drainage, preventing trapped resin in hollow models.- Tip: Check your slicer’s cross-section preview to avoid abrupt cross-sectional changes, even when tilting. Gradual transitions ensure even layer curing and reduce strain on the printer.
- Optimize Support Placement:
- Strategic Support Usage: Avoid placing supports on highly visible areas such as the face or decorative elements of your miniatures. Instead, place them in inconspicuous areas like the base or less detailed sections.
- Balanced Density: Use a mix of heavy supports for stability at the base and lighter supports for smaller islands and overhangs. This balance minimizes support marks while maintaining structural integrity during printing.
- Smooth Transitions:
When orienting, ensure that the model’s cross-sections evolve gradually. Abruptly increasing or decreasing the cross-section can result in stress points that lead to print failures.
Using Rafts and Drain Holes
For larger or hollow models, rafts and drain holes are indispensable:
- Rafts:
A raft provides a strong foundation for the print, improving adhesion to the build plate. This is especially helpful when printing complex or angled models, as it stabilizes the structure. - Drain Holes:
Hollowed miniatures need properly placed drain holes (at least 3 mm in diameter). These holes prevent resin from getting trapped inside, which can cause cracking or incomplete curing. Position the holes near the build plate and ensure they are not obstructed by supports.
Avoid Common Pitfalls
- Tilting Isn’t Always Better:
While tilting often reduces suction, it can sometimes increase cross-sectional areas in unintended places. Carefully evaluate how each slice transitions to avoid introducing new weak points. - Model Detail Preservation:
Pay attention to the model’s visible surfaces. Orient the miniature to minimize exposure of detailed or decorative areas to supports. - Use Slicer Tools Effectively:
Leverage tools like cross-section previews and support placement features in slicer software (e.g., Lychee, Chitubox) to identify potential problem areas.
Why Orientation Matters for 3D Printing Miniatures
Resin 3D printing miniatures requires meticulous attention to orientation because of the intricate details involved. Improper orientation can result in:
- Visible Layer Lines: These are especially noticeable on flat surfaces or steep overhangs.
- Lost Details: Poorly oriented models can obscure or damage fine details, especially when supports are removed.
- Failed Prints: Abrupt transitions, suction effects, or trapped resin often lead to incomplete or failed prints.
Key Takeaways for Optimizing Model Orientation
- Avoid flat orientations unless printing bases or simple components.
- Angle the model to reduce suction and enhance resin drainage.
- Use rafts for stability and ensure hollow models have adequate drain holes.
- Evaluate cross-sections carefully to avoid abrupt transitions.

One of the most frequent issues is poor adhesion of the first layer. This problem can result in prints detaching from the build plate during the process. First, To fix this, increase bottom exposure, then ensure your build plate is level and clean. Additionally, double-check that the printer settings, including exposure time, align with the resin specifications. If prints continue to fail, consider adjusting the room temperature. Keeping it consistently above 23°C (73°F) enhances print quality and adhesion.
2. Unwanted Supports or Marks
One common challenge when 3D printing miniatures is dealing with unwanted supports or the marks they leave behind. If you find supports difficult to remove, use pliers or a model knife carefully. Be gentle to avoid damaging intricate details on your miniatures.
To make support removal easier, consider adjusting the support settings in your slicing software. Increasing the support density, while reducing the size of the support tips, can make the supports easier to remove without damaging your print. This adjustment provides more stable supports while keeping them less intrusive, ensuring a smoother post-processing experience.
For any imperfections that remain, sanding can significantly improve the surface finish. Start with lower grit sandpaper to remove rough spots, then transition to finer grit for a smoother, more polished result. Additionally, using a hot air gun or dipping the miniatures in hot water can help make support removal easier, as the resin becomes more flexible, reducing the risk of damaging the model.
3. Warping or Bending After Curing
Miniatures may sometimes warp or bend after the curing process. One of the causes of warping might be that your prints absorb uncured resin. To prevent this, do not leave minis on the build plate, and wash the prints as soon as possible. It is also important to ensure proper post-curing conditions. Use a UV cure station to provide even exposure, and remember to flip your miniatures over during the process for consistent curing. This practice helps eliminate unevenness and ensures your models maintain their intended shape.
4. Uncured Resin Residue
Finding uncured resin residue on your prints can be frustrating. Thorough washing is crucial to remove this residue effectively. Use isopropyl alcohol (IPA) or an ultrasonic cleaner, and be sure to follow the manufacturer’s recommendations for your specific resin, such as TGM-7 or AMD-3. A careful washing process can save you from potential health risks associated with uncured resin.
5. Layer Misalignment
Layer misalignment results in visible lines or uneven layers that disrupt the smooth appearance of your finished print. This common issue often arises from z-axis instability or insufficient support structures. A wobbly z-axis can cause layers to shift slightly during the printing process, while weak or improperly placed supports fail to stabilize the model, leading to misaligned layers.
To address z-axis issues, check that the z-axis screw and rods are secure and well-lubricated. Tighten any loose components, and ensure the printer is placed on a stable, level surface to minimize vibrations. If support structures are the cause, refine your slicer settings. Adding thicker supports or increasing the density of light supports can provide better stability for delicate or overhanging parts. Additionally, consider adjusting the contact size of support tips—larger tips can offer more reliable adhesion to the model without being too difficult to remove post-print.
Taking these steps not only resolves layer misalignment but also improves the overall quality of your prints. For more in-depth troubleshooting tips and advanced solutions, visit our blog post on layer misalignment in resin 3D printing.
