How to Prepare Your 3D File for Printing with Resin
3D printing with resin is an exciting way to bring your designs to life with high precision and exceptional detail. However, to achieve the best results, it’s essential to properly prepare your 3D file before printing. Here’s a guide to help ensure a smooth printing process and high-quality output with our selection of 10 resins.
1. Choose the Right File Format
Most 3D printers using resin-based printing typically accept STL files. This is the most common format for 3D printing. Make sure to export your design in this format, as it’s compatible with our resin printing process.
2. Check Your Model for Errors
Before sending your file to print, it’s important to inspect it for any potential issues like non-manifold geometry, holes, or intersecting surfaces. Use repair tools available in software such as Meshmixer or Netfabb to correct these issues. A well-prepared model ensures a smoother printing process and better final results.
3. Scale and Orient Your Model
To ensure your model is the correct size, check its dimensions in your 3D design software. The orientation of your model is equally important—orienting your model properly can minimize the need for support structures and optimize the surface quality of the print, especially with resins like Formlabs Grey Resin V5 or Formlabs Black Resin V5, which benefit from strategic positioning to reduce the visibility of layer lines.
4. Wall Thickness and Detail Considerations
When designing your model, keep in mind the recommended wall thickness for resin printing. Thin walls may result in weak or fragile parts, while excessively thick walls can waste material. Resin-based prints generally allow for more detailed models, but ensure you check the resin’s specifications to determine the appropriate wall thickness for the selected material, such as Formlabs White Resin V5 for clean, detailed prints.
5. Consider Support Structures
If your design includes overhangs or intricate features, support structures will likely be necessary. Resin prints require supports for parts that need to be suspended in mid-air during the printing process. Most slicer software provides support generation tools, and it’s important to ensure supports are positioned in a way that minimizes damage to the surface while also reducing material waste. Resins like Formlabs Durable Resin and Formlabs High Temp Resin are ideal for functional prototypes that may require stronger support.
6. Export and Test in a Slicer
Once your file is ready, load it into a slicer like PreForm (designed for Formlabs resins) to preview the layers and optimize print settings. You can adjust infill, layer height, and print speed based on the resin you’re using. For instance, Formlabs Rigid 10K Resin may need different slicer settings than Formlabs Silicone 40A Resin, due to the different properties and required print characteristics of each material.
Choosing the Right Resin for Your Project
The resin you choose plays a vital role in achieving the desired strength, flexibility, and finish for your 3D printed project. Here’s a guide to help you select the best resin for your needs from our exclusive selection of 10 high-quality resins:

Ideal for soft, stretchable parts like medical devices, seals, and soft robotics, Formlabs Silicone 40A Resin mimics the properties of silicone rubber, providing flexibility and durability in one.
Choosing the Right Finish
Once you’ve selected the right resin, you can enhance your 3D printed model with various finishes such as sanding, painting, or applying a clear coat. This can elevate the appearance and functionality of your printed object, especially when using high-detail resins like Formlabs Clear Resin V5 or Formlabs White Resin V5.
By carefully preparing your file and choosing the right resin for your project, you’ll achieve exceptional results with minimal issues, ensuring your 3D printed project is both functional and visually appealing.
