About the Project
Who We Are
The project is the result of a collaboration between academic institutions and students. This partnership of experts in medicine, biochemistry, computer science, and education ensures that the tool is both methodologically and technically balanced.
The project is a joint effort of:
• Department of Chemistry Education and Humanities, University of Chemistry and Technology, Prague (UCT Prague)
• First Faculty of Medicine, Charles University

Why It Was Created
We believe that to truly understand molecular shape, spatial interactions, and the properties of bioorganic molecules, it is essential to work with intuitively understandable 3D models. Digital visualization is useful but often limited — it requires specialized software and is not ideal for teaching or physical demonstration. Building molecular models using kits is time-consuming and technically demanding, and preparing printable models can be complicated. That’s why our project was created — to make 3D printing of molecules more accessible, faster, and user-friendly.
What It Can Do
Our application allows you to:
- Automatically import molecular data from services like PubChem
- Upload your own files (
.sdf) - Generate 3D models in various representations
- Color-code atoms and choose the model quality
- Optimize models for printing and export them for slicers (e.g. PrusaSlicer)
- Support multi-color 3D printing of molecular models
Thanks to the application, the preparation time for printable models can be reduced from molecular data to just a few minutes — much more efficiently than through manual processing.
Technical Foundations
- Language: TypeScript
- GUI: SvelteKit, Bootstrap
- Data integration: connection with public databases (PubChem, COD)
- Representations: van der Waals (space-filling, Spheres), Ball-and-Stick, Stick
- Optimization: control of detail, hydrogen addition, model refinement, and more...
- Export outputs: print-ready formats for slicers
Our goal is to make 3D molecular printing accessible to as many people as possible — students, researchers, and educators alike.
