We Convert Your CT Scan To 3D Print

Use our service to convert your CT scan into a 3D printed model, delivered to you!

Using advanced segmentation tools in our own software and in-house 3D printing facilities, our talented team can help you to visualise patient-specific anatomy with 3D printed models of patient-specific anatomy segmented from CT scans.

Disclaimer: Patient specific anatomical models created from CT scans are for educational and research purposes only and must not be used for diagnosis or planning of treatment.

Benefits of 3D Anatomical Models

The use of artificial intelligence in medicine and particularly medical imaging is growing a massive Compound Annual Growth Rate (CAGR) of 30.4%.

Before AI models can make it to market, vast datasets of labelled medical images are required to train convolutional neural networks to identify and automatically segment organs-at-risk, various pathologies and anatomical structures.

3Dicom R&D allows for creation of highly accurate segmentation of anatomy with both manual and rule-based segmentation and island removal which can then be exported as multi-class and binary masks for use in these training datasets as well as for the creation of physical 3D printed anatomical models.

Our development team are currently working on APIs and SDKs to allow researchers to integrate and test the outputs of their machine learning and AI models inside of the R&D software for a full end-to-end medical image research tool.


Step 1: Specify Your Requirements & Request a Quote

The process of turning your CT scan into a 3D printed model starts with 3 simple steps:

  • Provide your scan,
  • Accept the terms and conditions & data sharing terms, and
  • Tell us what part(s) of your anatomy you would like to 3D print.

Depending on the size and quality of your scan and your requirements, we will provide you a quote within 24 hours which includes costs for segmentation, printing and shipping to you.

As a general guide, 3D printing of bones is the most cost-effective, whereas creating models for soft tissue and organs is more difficult.

We also provide a DICOM to STL service so you can do the 3D printing yourself and leave the hard work of segmentation to us.

Step 2: We Convert DICOM to STL

Using a combination of AI, semi-automated techniques and manual tools in our 3Dicom R&D software, our team is able to extract the required detail from your scans to generate a series of segment masks.

These masks are compiled by the software and converted into an STL file using a marching-cube algorithm and various smoothing tools and then exported to the 3D printing software for a final check.

For more complex projects, we usually conduct a quick video call to verify that the segmented anatomical structures are as intended prior to starting the 3D printing.

Step 3: 3D Printing Anatomical Model

We’re constantly working on new integrations with 3rd party programs and toolkits to allow for in-silico modeling with full 3D volumetric and materials analysis.

Users also have the ability to use the in-built Medical Computer Aided Design (MCAD) functionality to import, manipulate and position medical devices from screws to patient-specific implants ‘into’ the virtual patient’s anatomy.

Test your hypotheses and the fit and design of your next medical device with virtual patients created from real patient’s radiological images.

Step 4: We Ship Your Anatomy to You

A full suite of segmentation tools allow for researchers, educators and even students to segment particular anatomical structures with different colours and labels.

Using semi-automated techniques such as threshold flood-fill, level tracing, and island removal, scans can be rapidly segmented with small edits made manually.

Whilst in the software, segments can be viewed in 3D and overlaid on the initial scan to provide a contextual understanding of that anatomy, pathology or even implant.

Segmented anatomy and pathology can be exported to STL, OBJ or PLY file types for use in modeling software and also for the manufacture of physical 3D anatomical models using 3D printing or traditional manufacturing.

Frequently Asked Questions

How do you convert DICOM to STL?

To convert the series of 2D medical images from a DICOM scan (usually a CT scan) into a STL, we use a process called segmentation.
This is effectively colouring particular anatomy to extract it from the overall image and is performed using our 3Dicom software which allows us to view the DICOM file in 3D as we segment it.

Can I print the 3D model myself?

If you’ve already got your own 3D printer or access to one, we offer a simple DCM to STL conversion service to segment the anatomy you specify and send you the STL files to 3D print yourself. Please contact us for more details.

How long does it take to segment & 3D print my scan?

The process of segmenting anatomy can be a painstakingly long and varies depending on the quality of the scan, the anatomy being segmented and similarity of density with surrounding tissue. The 3D printing time depends on the size of the scan, however we usually run the 3D prints overnight and conduct post-processing in the morning before shipping.

How expensive is the 3D printing?

The cost of 3D printing your non-diagnostic anatomical model varies depending on the size of the print, the material used and the amount of post-processing required.
Typically, the resin based printers we use cost around $125 per litre of resin used, with most 3D printed models costing around $50-60 after post-processing.

What 3D printers and material do we use?

We have 3D printing facility for non-diagnostic anatomical models both in-house and outsourced through our manufacturing partners. Our in-house facility features a Phrozen 8K Mega with a huge build volume as well as a Formlab Form 2 printer.
Our manufacturing partners have EOS M290 titanium 3D printers for custom medical implants and guides along with Nylon printers for biomodels.
