• Larger Print Volume: Build volumes on FDM printers tend to be larger than resin printers, allowing you to print bigger miniatures or multiple miniatures at once.

Cons for Miniatures:

• Lower Resolution: FDM printing uses a larger nozzle compared to resin printers, resulting in a visible layer line on the final product. This can be a challenge for capturing fine details on miniatures.
• Support Structures: FDM printing often requires complex support structures to print overhangs. Removing these supports can leave blemishes on the miniature, requiring additional cleaning and potentially damaging delicate features.
• Long Printing Times: Due to the layer-by-layer deposition process, printing miniatures on FDM printers can take significantly longer compared to resin printers.

Stereolithography (SLA)

SLA printers utilize a vat of liquid resin and a laser to cure the resin layer-by-layer, solidifying the desired 3D model. This process offers incredible precision and resolution, resulting in highly detailed prints with smooth surfaces.

Best Uses: SLA printing excels in creating intricate and detailed models, perfect for miniature figurines, jewelry prototypes, and dental applications.

Pros for Miniatures:

• Exceptional Detail: SLA printers produce miniatures with exceptional detail, faithfully capturing even the most delicate features on your 3D model.
• Smooth Surface Finish: Unlike FDM printing, SLA offers a smooth surface finish, minimizing the need for extensive post-processing like sanding and filling.
• Wide Material Variety: A growing range of SLA resins caters to different needs, from high-detail standard resins to flexible or castable resins for specific applications.

Cons for Miniatures:

• Resin Cost: Resin can be more expensive than FDM filament, making SLA printing potentially costlier, especially for larger prints.
• Safety Measures: Liquid resin can be messy and requires handling with care. Proper ventilation and use of gloves are crucial during the printing process.
• Post-Processing: While minimal compared to FDM, SLA prints still require cleaning and potentially curing under UV light to ensure complete solidification.

Digital Light Processing (DLP)

DLP printers utilize a vat of liquid resin and a digital projector to create detailed 3D objects layer by layer. The projector casts light onto the resin surface, selectively curing (solidifying) thin layers according to the digital model. The platform holding the printed object descends incrementally, and a new layer of resin is applied for continued light curing, building the miniature from the ground up.

Best Uses:

• Highly Detailed Miniatures: DLP printers excel at producing miniatures with exceptional detail and smooth surface finishes, ideal for tabletop gaming figures and collectible figurines.
• Fast Printing Times: Compared to FDM, DLP printing boasts faster printing times, especially for smaller objects like miniatures.
• Wide Range of Resins: DLP offers a variety of resin types with different properties, allowing for customization of flexibility, strength, and transparency for specific miniature needs.

Pros for Miniatures:

• Superior Detail: DLP captures intricate details and crisp lines, creating miniatures that are true to the digital model.
• Smooth Surface Finish: The layer-by-layer curing with light eliminates visible layer lines, resulting in a smooth surface finish ideal for painting miniatures.
• Accuracy: DLP printing offers high dimensional accuracy, ensuring your miniatures match the intended size and proportions.

Cons for Miniatures:

• Resin Cost: Resin can be more expensive than filament used in FDM printing.
• Post-Processing: DLP prints require a cleaning process to remove excess resin and potentially involve curing under UV light for optimal strength. This adds extra steps compared to FDM printing.
• Resin Safety: Liquid resin can be harmful if not handled properly, requiring the use of gloves and proper ventilation during printing and post-processing.

Selective Laser Sintering (SLS)

 SLS utilizes a powerful laser to selectively sinter (fuse) tiny powder particles layer by layer, building the 3D model from the ground up.

Best Uses: SLS excels in printing complex geometries with high dimensional accuracy and a smooth surface finish. It’s ideal for functional prototypes, mechanical parts, and even full-color models due to the availability of multi-material printing capabilities.

Pros for Miniatures:

• High Accuracy: SLS produces miniatures with exceptional detail and sharp features, perfect for capturing intricate armor designs or facial expressions.
• Durability: The sintered powder material creates strong and rigid models, ideal for miniatures that need to withstand some handling during gameplay.
• Multi-Material Printing: Some SLS printers offer the ability to print miniatures in multiple colors, eliminating the need for painting in some cases.

Cons for Miniatures:

• Cost: SLS printers tend to be more expensive than resin printers, making them a less budget-friendly option for hobbyists.
• Limited Material Options: While some color options exist, the material selection for SLS might be more limited compared to the wide variety of resins available for SLA printing.
• Post-Processing: SLS printed parts often require additional cleaning and post-processing steps to remove excess powder.

Factors to Consider When Choosing a 3D Printer

Detail and Resolution 

Precision is key: Look for printers with high resolutions (measured in microns, lower is better) to capture the intricate details of your miniatures, like weapons, armor, and facial expressions. Stereolithography (SLA) and Digital Light Processing (DLP) printers, also known as resin printers, generally offer the finest detail for miniatures.

Material Options and Flexibility

Resin reigns supreme: Resin printing offers a vast selection of resins with varying properties. Choose a resin with good detail capture and consider options with specific features like flexibility or high strength depending on your miniature’s needs. SLS printers offer limited material options but might be suitable if you prioritize multi-color printing or exceptionally strong miniatures.

Ease of Use and Maintenance

Consider your experience level: Resin printers require more hands-on involvement than some technologies. Factors like resin handling, proper ventilation, and post-processing steps need to be considered. Filament printers (FDM) can be more user-friendly for beginners, but their detail level might not be ideal for highly intricate miniatures.

For most miniature printing needs, SLA/DLP resin printers offer the best combination of detail, material options, and affordability compared to SLS printers. However, if you’re a beginner or prioritize ease of use, an FDM printer might be a good starting point, keeping in mind the trade-off in detail quality.
