Introduction: The Magic of 3D Printing Miniatures
Whether you're a tabletop game enthusiast, a model train hobbyist, or a designer creating intricate scale models, 3D printing miniatures can open up a world of possibilities.
3D printed miniatures are small-scale models created using 3D printers. They can range from detailed figurines for role-playing games like Dungeons & Dragons, to architectural models, to tiny replicas of historical artifacts. The process involves translating a digital 3D model into physical form, layer by layer, using a 3D printer.
The beauty of 3D printing miniatures lies in its ability to produce highly detailed and personalized objects. It gives you the power to create unique characters, buildings, and artifacts that are only limited by your imagination. Moreover, 3D printing miniatures can be a cost-effective alternative to purchasing commercially available miniatures, especially if you're a prolific gamer or modeler.
Best Practices For Slicing
Slicing is the process of converting a 3D model into a series of thin layers that the 3D printer can print one at a time. This is done using slicing software, which also allows you to customize various print settings such as layer height, print speed, and infill density. For miniatures, it's crucial to use a small layer height to capture the fine details of the model.
Support structures are another important aspect of 3D printing miniatures. These are temporary structures added to the model to prevent overhangs (parts of the model that extend outwards without any support underneath) from sagging or collapsing during printing. After printing, the support structures are removed to reveal the final miniature.
Hollowing out a miniature before printing is a technique often used in resin 3D printing to save material and reduce print time. This involves creating a hollow interior within the model, leaving only a thin outer shell. However, care must be taken to ensure that the shell is thick enough to maintain the structural integrity of the miniature.
Materials for 3D Printing Miniatures: A Comprehensive Breakdown
The choice of material can significantly impact the quality of your 3D printed miniatures. For resin 3D printers, there are several types of resins available, each with its own properties and applications. Let’s go over some of the most common filaments that we use for miniatures.
Standard Resin
Standard resin is the most commonly used type for 3D printing miniatures. It offers a good balance between cost and detail, making it a versatile choice for a wide range of miniatures. However, standard resin can be brittle, so it may not be the best choice for miniatures that will be handled frequently or subjected to stress.
When using standard resin, it's recommended to use a layer height of 0.05mm for optimal detail. The recommended print speed is 50mm/s, and the infill density should be set to 100% for solid miniatures. For hollow miniatures, an infill density of 20% is typically sufficient.
Tough Resin
Tough resin is more durable and resistant to stress, making it ideal for functional parts or miniatures that need to withstand handling. However, it is more expensive than standard resin and may not capture fine details as well.
When printing with tough resin, a layer height of 0.1mm is recommended for the best balance between detail and strength. The print speed should be set to 40mm/s, and the infill density should be 100% for maximum durability.
Water Washable Resin
Water washable resin is a convenient option that can be cleaned with water instead of alcohol, making post-processing easier and safer. However, it tends to be more brittle than standard resin.
When using water washable resin, a layer height of 0.05mm is recommended for the best detail. The print speed should be set to 50mm/s, and the infill density should be 100% for solid miniatures or 20% for hollow miniatures.
Flexible Resin
Flexible resin can produce miniatures with bendable parts. It's ideal for miniatures with thin, delicate features that might break under pressure when printed with standard resin.
When printing with flexible resin, a layer height of 0.1mm is recommended for the best balance between flexibility and detail. The print speed should be set to 30mm/s, and the infill density should be 100% for maximum flexibility.
Cost, Quality, and Print Time: A Comparative Analysis
The choice of material also affects the cost-effectiveness of 3D printing miniatures. Resin can be expensive, but by using techniques like hollowing, you can save on material costs. Moreover, 3D printing allows you to create custom miniatures that may not be available commercially, adding value beyond the cost of materials.
When comparing the cost of different materials, standard resin is typically the most affordable option, followed by water washable resin, tough resin, and flexible resin. However, the cost per miniature can vary depending on the size and complexity of the model, as well as the print settings used.
In terms of quality, resin printers generally produce higher detail and smoother surfaces than FDM printers. However, the quality can also be influenced by the type of resin used. Standard and water washable resins are capable of capturing fine details, while tough and flexible resins are better suited for producing durable and flexible parts, respectively.
Print time is another important factor to consider. Resin printers are typically slower than FDM printers due to the curing process involved in resin printing. However, the print time can also be influenced by the layer height and print speed settings. Lower layer heights and slower print speeds will result in longer print times, but can also improve the detail and quality of the print.
Designing Your Own Miniatures, Step-By-Step
Designing your own miniatures can be a rewarding experience, allowing you to bring your unique ideas to life. There are several software options available for 3D modeling, ranging from beginner-friendly options like Tinkercad to professional-grade software like Blender or ZBrush. However, the process of designing a miniature is not as simple as just picking a software and starting to model. It requires careful planning, understanding of the limitations of your 3D printer, and a good grasp of the design principles specific to miniatures.
Step 1: Conceptualizing Your Miniature
Before you even open your 3D modeling software, it's important to have a clear idea of what you want to create. This involves conceptualizing your miniature, sketching out its design, and considering its purpose and functionality.
Are you creating a character for a tabletop game? If so, what are its abilities, characteristics, and role in the game? These factors can influence the design of your miniature. For instance, a warrior character might be designed with heavy armor and a large weapon, while a rogue character might be designed with stealthy attire and a smaller, more concealed weapon.
Sketching out your design can help you visualize your miniature and plan out its details. This doesn't have to be a detailed or professional sketch - a simple doodle can suffice. The goal is to have a visual reference that you can refer to during the design process.
Step 2: Choosing the Right 3D Modeling Software
The choice of 3D modeling software can greatly influence your design process. Different software have different features, capabilities, and learning curves. For beginners, software like Tinkercad or SketchUp can be a good starting point. They are user-friendly and have intuitive interfaces, making it easy to learn the basics of 3D modeling.
For more advanced users, software like Blender or ZBrush offer more features and capabilities. These software allow for more detailed and complex designs, but they also have steeper learning curves. It's important to choose a software that matches your skill level and the complexity of your design.
Step 3: Preparing the Model for 3D Printing
Once you've created your 3D model and chosen the software you’d like to use, the next step is to prepare it for 3D printing. This is done using a slicer software, which converts the 3D model into a series of thin layers that the 3D printer can print one at a time. The slicer software also allows you to customize various print settings such as layer height, print speed, and infill density.
For this guide, we will use Creality Slicer, but other common slicers include Cura, PrusaSlicer, and Simplify3D. To import your model into Creality Slicer, open the app, click File > Load Model File, and select the 3D Benchy model from the folder where you downloaded it. This will load the 3D model into Creality Slicer so it can be prepared for 3D printing.
Creality Slicer offers two modes for slicing STL files: Quickprint and Full. Quickprint allows you to choose a material profile, platform adhesion aid, and also toggle support material on and off, while the Full mode offers more granular control over the print settings. For this guide, we will use Quickprint to cover all the basics.
Here's what to choose on the menu:
- Material: This is the material being used for the print. Since we're using PLA, we'll select "Common PLA" here.
- Profile: Selecting a profile automatically adjusts all of the settings used in making a print, including layer height, print speed, travel speed, etc. We're going to use "Normal (0.15mm)", which strikes a good compromise between speed and quality.
- Other: The only option here is to toggle support material on and off. Because the 3D Benchy doesn't require support material, we'll leave this unchecked.
Once you've made your selections, click on the "Slice" button at the bottom right of the screen. This will slice the 3D model into layers and generate a preview of the print. You can use the slider on the right side of the screen to view each layer of the print.
Step 4: Exporting the Sliced Model
After slicing the 3D model, the next step is to export the sliced model as a G-code file. G-code is a language that 3D printers understand. It tells the printer where to move, how fast to move, and what to do at each point.
To export the sliced model, click on the "Save to File" button at the bottom right of the screen. This will open a dialog box where you can choose where to save the G-code file. If your 3D printer uses a microSD card for transferring G-code files from your computer to the printer, you can save the file directly to the card.
Step 5: Preparing the 3D Printer
Before you can start printing, you need to prepare your 3D printer. This involves calibrating the build platform and loading the filament.
Calibrating the build platform ensures that there is a consistent gap between the nozzle and the build platform at all points on the build plate. This is crucial for ensuring that the first layer of the print adheres properly to the build plate. Calibration is typically done by adjusting the screws at the corners of the build plate while moving the nozzle across the build plate.
Loading the filament involves feeding the filament into the extruder of the 3D printer. The extruder heats up the filament and pushes it through the nozzle onto the build plate. Make sure to load the filament according to the manufacturer's instructions.
Step 6: Starting the Print
Once your 3D printer is prepared, you can start the print. This involves transferring the G-code file to the printer and starting the print from the printer's control panel.
If your printer uses a microSD card for transferring files, insert the card into the printer's card slot. Then, navigate to the "Print" or "Print from SD" option on the printer's control panel, select the G-code file you want to print, and press "Start" or "Print".
As the print starts, the printer will heat up the extruder and the build plate to the temperatures specified in the G-code file. Once the temperatures are reached, the printer will start printing the first layer of the model.
Step 7: Monitoring the Print
During the print, it's important to monitor the printer to ensure that everything is going smoothly. Pay attention to the first layer of the print, as this is the most critical layer. If the first layer does not adhere properly to the build plate, the rest of the print is likely to fail.
Also, keep an eye on the filament feed. If the filament gets tangled or runs out, the print will fail. Some printers have filament runout sensors that pause the print when the filament runs out, but not all printers have this feature.
Step 8: Removing the Print
Once the print is finished, the next step is to remove the print from the build plate. This should be done carefully to avoid damaging the print or the build plate.
First, let the build plate cool down. Trying to remove the print while the build plate is still hot can cause the print to warp. Once the build plate is cool, you can use a spatula or a similar tool to carefully pry the print off the build plate.
Step 9: Post-Processing the Print
After removing the print from the build plate, you may need to do some post-processing to improve the appearance of the print. This can involve removing support structures, sanding rough edges, and painting the print.
To remove support structures, you can use pliers or a similar tool. Be careful not to damage the print while removing the supports. For sanding rough edges, you can use sandpaper or a file. Start with a coarse grit and gradually move to a finer grit for a smooth finish.
Painting the print can bring out the details and make the print look more realistic. You can use acrylic paints and a brush for painting. Start with a base coat and then add layers of color, allowing each layer to dry before applying the next.

Advanced Techniques for Designing Miniatures
For those who already have some experience with 3D printing miniatures, let’s go over some advanced techniques that you can use beyond the basic process to achieve a high level of detail and realism.
One such technique is digital sculpting. Digital sculpting, also known as 3D sculpting, is a process of creating 3D models on a computer that simulates traditional sculpting techniques. This technique is commonly used in industries like film, animation, and video games to create detailed and realistic characters and objects.
Digital sculpting is done using software like ZBrush or Blender. These software offer tools like brushes, which simulate the effect of traditional sculpting tools, and layers, which allow you to work on different parts of the model independently.
One of the key features of digital sculpting is the ability to work with high-polygon models. This allows you to create intricate details that would be difficult to achieve with traditional 3D modeling techniques. However, working with high-polygon models can be computationally intensive, so a powerful computer is recommended for digital sculpting.
Another advanced technique is the use of Boolean operations. Boolean operations allow you to add, subtract, and intersect 3D shapes to create complex models. This technique is particularly useful for creating hard-surface models like armor or machinery.
For example, you can start with a basic shape like a cube or a sphere, and then use Boolean operations to add or subtract other shapes to create a more complex model. This technique allows you to create intricate details with precise control over the shape and size of each element.
Another technique that can be used to create highly detailed miniatures is the use of displacement maps. Displacement maps are images that are used to add detail to a 3D model by altering its geometry. This technique is often used in conjunction with digital sculpting to add fine details like wrinkles, scars, or textures to a model.
To use a displacement map, you first need to create a high-polygon model in your digital sculpting software. Then, you can create a displacement map based on this model. The displacement map is then applied to a low-polygon version of the model, adding the details from the high-polygon model to the low-polygon model.
These advanced techniques can help you create highly detailed and realistic miniatures. However, they also require a high level of skill and experience. If you're new to 3D modeling, it's recommended to start with the basic techniques and gradually move on to the advanced techniques as you gain more experience.
Our team at Accelerate3D have years of experience in techniques like these, and many more. We support you throughout the printing process and ensure that you not only get to make your visions a reality, but truly be a part of the iterative process that we use to print.

Where to Find 3D Print Files for Miniatures
Not everyone’s a CAD wizard, so for anyone that would prefer a more handsfree process, there are plenty of resources where you can find 3D print files. Websites like Thingiverse, MyMiniFactory, and Cults3D offer a wide range of free and paid models for all types of miniatures.
When choosing a 3D print file, there are several factors to consider. First, you need to consider the level of detail of the model. High-detail models can look impressive, but they also require a high-quality 3D printer and a lot of time to print. On the other hand, low-detail models can be printed quickly and easily, but they may not look as impressive.
Second, you need to consider the scale of the model. The scale of the model should match the scale of your game or display. For example, if you're printing miniatures for a tabletop game, the scale of the miniatures should match the scale of the game board and other game pieces.
Third, you need to consider the type of 3D printer you have. Some models are designed specifically for FDM printers, while others are designed for SLA printers. Make sure to choose a model that is compatible with your 3D printer.
Finally, you need to consider the complexity of the model. Complex models can be challenging to print and may require advanced techniques like support generation and post-processing. If you're new to 3D printing, it's recommended to start with simple models and gradually move on to more complex models as you gain more experience.
In addition to these online resources, there are also several software tools that you can use to create your own 3D models. These include Tinkercad, a simple and intuitive 3D design tool for beginners; Fusion 360, a powerful CAD tool for advanced users; and Blender, a free and open-source 3D modeling software that is popular among professionals.
One of the most popular software for designing miniatures is Hero Forge. Hero Forge offers a user-friendly interface that allows you to create detailed custom miniatures with a range of races that are found in games like D&D and Warhammer.

Once you're satisfied with your design, you can order your custom miniature to be shipped to your door, or download it as an STL file for 3D printing.
Eldritch Foundry is another option for customizing your tabletop miniatures. It offers a character creator that allows you to craft your legend with a wide variety of customization options.
When choosing a software for designing your miniatures, consider your skill level and the features you need. Beginner-friendly software like Tinkercad and Hero Forge are great for getting started, while advanced software like Fusion 360 and Blender offer more powerful features for professional-quality designs.
3D Printing Miniatures: A Cost Analysis
Is 3D printing miniatures cheaper than buying them? The answer depends on several factors, including the cost of your 3D printer, the cost of materials, and the amount of time you spend on printing and post-processing.
The upfront cost of a 3D printer can be significant, especially for high-quality resin printers. However, once you have the printer, the cost per miniature can be quite low, especially if you're printing multiple miniatures from the same design.
The cost of materials can also add up, especially for resin printing. However, techniques like hollowing can help reduce material usage and save costs. For example, a 500g bottle of standard resin can cost around $20-$30, and can be used to print several miniatures, depending on their size and complexity. If you hollow out your miniatures, you can potentially double or triple the number of miniatures you can print from a single bottle of resin.
Finally, don't forget to factor in the time you spend on designing or finding 3D models, setting up the print, and post-processing the miniatures. While this can be a labor of love for hobbyists, it's still an important consideration when comparing the cost of 3D printing versus buying miniatures.
For example, if you spend 10 hours designing a miniature, and your time is worth $20 per hour, that's $200 of your time invested in the design. If you then spend another 5 hours printing and post-processing the miniature, that's another $100 of your time. So the total cost of your 3D printed miniature would be $300, plus the cost of materials.
On the other hand, if you buy a similar miniature from a store, it might cost you $10-$20, but you save all the time and effort of designing and printing the miniature. However, you lose the customization and uniqueness of a 3D printed miniature.
In conclusion, while the upfront costs of 3D printing miniatures can be significant, the cost per miniature can be quite low, especially if you're printing multiple miniatures from the same design. Moreover, the ability to customize your miniatures and print them on demand adds value that can't be measured in dollars and cents.
Final Thoughts: The Future of 3D Printed Miniatures
3D printing has revolutionized the world of miniatures, offering unprecedented levels of customization and accessibility. As 3D printing technology continues to advance, we can expect even higher levels of detail and realism in 3D printed miniatures.
In the future, we may see more hybrid approaches that combine 3D printing with traditional miniature making techniques. For example, 3D printed parts could be combined with hand-sculpted elements to create unique, mixed-media miniatures. This could open up new possibilities for miniature design, allowing artists to combine the precision and repeatability of 3D printing with the organic, tactile qualities of hand-sculpting.
Moreover, as 3D printers become more affordable anduser-friendly, more people will be able to explore the world of 3D printed miniatures, whether for gaming, modeling, or simply for the joy of creating something tangible from a digital design. Happy printing!
