Over the past several years, I have designed a collection of 3D models for use in high-pressure laboratories and educational outreach. These models are available as STL files and can be readily sliced for most standard 3D printers.
You are welcome to download, print, and share these models for research, teaching, or outreach purposes. All files are available here. This page also includes photographs of the models in their printed form to help you visualize scale and assembly.
3D Models for Outreach
Diamond Anvil Cell Models
The diamond anvil cell models are designed to help demonstrate the components of a diamond anvil cell, how a cell is assembled and loaded, and how different anvil designs compare. They are useful both for laboratory training and for outreach demonstrations.
During outreach events, the models can also be used as an interactive puzzle activity. Students are challenged to “load” their own diamond anvil cell using tweezers, 3D-printed sample pieces, or natural stones. The activity can be scaled in difficulty:
Level 1: Load a sample and ruby sphere.
Level 2: Add a tripod assembly.
Level 3: Load multiple layers.
Below is an example of a Level 1 configuration, representative of a typical setup used for gas or liquid loading experiments.
Note: The 3D-printed gasket models are nearly watertight, making it possible to fill the sample chamber with water using a needle for demonstration purposes.
Link to stl files. These files include printable diamond anvils (flat, beveled, and toroidal designs) along with their corresponding gaskets. The models are fully scalable; simply adjust the print ratio to suit your needs and printer specifications.
Multi Anvil Cell Model
Link to STL files for a scalable COMPRES 10/5 multi-anvil cell assembly. These models allow students to explore how a high-pressure assembly is constructed and how each component fits together.
Students can practice assembling their own capsule and better understand the structure of a 10/5 assembly used in multi-anvil experiments. For a more realistic hands-on experience, thermocouples and heaters can be simulated using wire and aluminum foil.
3D Models for Research
Designing and 3D printing lab tools has become a hobby of mine. I have developed several slide holders with the same outer diameter as a diamond anvil cell, allowing for easy integration into a Raman setup and simplifying sample loading.
By matching the height of the diamond anvil cell, these holders make alignment and loading from a slide easier. Multiple design variations are available, print supports may be required depending on your printer and chosen configuration.
Keeping diamond anvil cells organized can be challenging, so I designed a dedicated storage box to securely hold diamond anvil cells, screw holders, and diamond boxes in one place.
Two versions are available:
- Version 1: No notch — the lid slides out easily for quick access.
- Version 2: Includes a notch — helps keep the lid securely closed.
Both versions are available online; choose the design that best fits your needs. Printing supports are required for this model.
Transporting diamond anvil cells, especially at the beamline, can quickly become a logistical challenge when working with multiple cells. To make this easier, I designed a transport tray that securely holds up to six diamond anvil cells, along with screw holders and essential tools.
The tray allows for safer, more organized handling and simplifies moving between preparation areas, microscopes, and the beamline.
Have an Idea?
Do you have ideas for new lab tools or outreach models? Would you like help designing a 3D model, or sharing one you’ve already created with the community?
I’m always happy to collaborate. If you’re interested in working together or contributing a model, please feel free to contact me.
