3D printed anatomy models for teaching and display
How to get skulls, hearts, bones and organ models 3D printed for a class or a display: where the files come from, labels, materials and what to avoid.
How to brief a maker for an anatomy or dental model
By the Medical 3D Parts editors, The Spool List · Published October 14, 2026
The short answer
Say what the model is for (teaching, display, practice or a prototype), attach the file or link its source and licence, and give the size, material preference, colours, labels, quantity, deadline and budget. Never include a patient's name or scans. A clear brief gets comparable quotes.
Makers quote from what you tell them. A brief that covers the points below gets quotes you can compare like for like.
Steps
- Purpose. "For a first-year anatomy class", "for a waiting-room display" or "fit prototype, not for patient use". The purpose also decides what the model is: regulators look at "the claims about what the product is and what it does" [1].
- File. Attach the STL or STEP, or link the open library it comes from and its licence. No patient scans: for diagnostic models, Stratasys, a printer maker, notes that "Validation applies to the printer, its compatible materials and software" [2], which is not this kind of job.
- Size or scale. Life-size, enlarged (say by how much) or the exact dimensions.
- Parts. Which parts come apart, and how they attach (pegs, magnets).
- Material. Resin for fine detail, FDM for larger or handled models, or leave it to the maker.
- Colours and finish. Colour-coded structures, painted or printed in colour, matte or smooth.
- Labels. Numbered structures and a key card, and the line "Education and display model. Not a medical device."
- Quantity, deadline, delivery address and budget range.
