CAMES 3D Lab provides 3D printing to the clinics affiliated to RegionH. The centre consists of a printer farm of 10 printers covering the classic FDM printers as well as a single SLA printer, which allows printing of different materials. We print mainly on the FDM printers and use PLA (PolyLaticAcid, a type of plastic). However, the choice of material depends on the specifications of the desired object.
3D printing allows the clinic to print patient-specific cases based on CT scans. It can be used for example for teaching, patient orientation, treatment or surgery planning. It provides a tangible 3D element that fully reflects the case at hand. 3D printing can also be used non-specifically to rehearse rare cases that clinicians otherwise only see a few times a year. 3D printing can also be used to produce so-called 'gizmos' that are missing in the department.
Please contact us if you need assistance or advice.
The 3D printing centre is managed by medical engineer Kiki (Kirstina) Vestersøe (MSc) and medical engineer Morten Bo Søndergaard Svendsen (MSc, PhD). In addition, it is run on a daily basis by talented and dedicated student assistants, who are primarily engineering students.
The 3D printing centre is part of CAMES Engineering, which has dedicated people developing both products, prototypes, software and new technologies in a larger garage/maker space environment in interaction with companies, clinicians and hospitals.

Current projects and tasks
Bolus production for difficult anatomies in radiotherapy
In radiotherapy treatment for skin cancer, a silicone-like mat, called a bolus, is used to spread the radiation and avoid damage to the surrounding skin. For large and regular anatomies, a generic mat can be purchased for the purpose. But for awkward anatomies, such as noses and ears, patient-specific solutions may be better.
In this project, CAMES has a strong collaboration with the Department of Medical Technology (CIMT) at Rigshospitalet and the Radiation Therapy Department at Rigshospitalet, where we produce patient-specific bolus mats based on scans.
In this project, we investigated the best 3D scanners to avoid putting patients in a CT scanner. And we've developed optimised code for our CAD programme to ensure we deliver an accurate but quickly produced product.
Bolus falls into the 'custom medical device' category of the MDR (medical device regulations). We therefore also take care of registration with the Danish Medicines Agency and the associated quality assurance.

3D printed training hearts for cardiology
The project was initiated at the request of the Department of Cardiac Diseases at Gentofte Hospital. The aim was to visualise patient-specific cases - with various irregularities - before the patient went to the operating table. In collaboration with the Department of Medical Technology at Rigshospitalet (CIMT), a heart from a CT scan was segmented - and a heart was printed. As it was just for visualisation, it was printed in PLA plastic.
The patient often has the CT scan one to two days before he/she lies on the table. Therefore, time is an important factor. Printing the full heart took over 20 hours. So instead, work was done to segment the parts of the heart that are of interest to the doctor.
The possibility of virtual reality is also being explored, as the time perspective is shorter.

Washing plugs for multistage blood pressure cuffs
When blood pressure cuffs need to be washed, a plug is used at the end of the pressure cable. This is done to avoid water in the cuff and later in the blood pressure devices. These are no longer sold individually from the supplier, but with a new cuff.
Therefore, the Child and Adolescent Clinic at Rigshospitalet asked the Department of Medical Technology (CIMT) and CAMES if this task could be solved internally. CAMES has produced a mat with 6x6 silicone plugs, which can soon be ordered via the 'brick system' throughout the region. Currently they are available to order through the Medical Technology Department and their 'Medusa' system.
The project has offered a test and validation of the plugs' properties, in collaboration with the Children and Youth Clinic. This has led to new guidelines for cuff washing and drying times.

Ear clips for keloid treatment
Patients with keloids, scar tissue that grows uncontrollably, are most often treated with surgery or steroid injections and pressure (sometimes both). For the latter, precise pressure is important, as too much pressure will provoke more growth, while too little pressure will leave room for continued growth.
In this project, we are investigating whether these clips can be produced patient-specifically using 3D scanning and CAD software. The clips are produced on our SLA printer with biocompatible resin that is ISO-approved for continuous skin contact. These clips fall into the category of 'custom medical devices' in the MDR (medical device regulations). CAMES is therefore responsible for registration with the Danish Medicines Agency and the associated quality assurance.

We have the expertise, knowledge and overview to meet your needs. Bring us your idea and we'll guide you. Whether the need is 3D printing, VR, silicone moulding or something else entirely.
In collaboration with CAMES Innovation, we can help you turn your idea into a product and provide assistance with. MDR if you need it. Get in touch - and you're always welcome to drop by our facilities for a chat about the possibilities.
Print order of 3D objects
If you have an idea but don't know how to proceed. Or need some sparring over a prototype, feel free to get in touch.
We are involved in iterative steps and can also provide guidance on mechanical properties, material selection and legislation. MDR. We also have a collaboration with Rigshospitalets Innovationscenter, so if we can't help you in-house, we can refer you to someone who can.
CAMES has 10 FDM printers and 1 SLA printer and can therefore quickly produce and deliver the desired product. See our current projects for inspiration.
Reordering of 3D printed objects
There is no need to reinvent the wheel.
Therefore, once we have gone through the iterative process and have a finished product, it will be included in our product catalogue and you will be able to easily order the desired product, with fast delivery.
Depending on the volume of the order and the size of the items, we can deliver day-to-day.
3D printing step-by-step
How we do it
CAMES manages the entire technical process
Our approach is that we take care of the entire technical process, unless the customer wants to produce the CAD files themselves. The customer is of course welcome in our 3D workshop to participate in slicing as well as printing. For iterative processes, communication is at the customer's request (teams, physical meetings, etc.)
Step 1: CAD drawing of the 3D objects
The desired objects are first drawn digitally using computer aided design (CAD). Here, you can construct exactly the designs you want and can optimise them continuously as needed. The designs, prototypes or final versions, are saved in STL format so that they can be printed.
Step 2: Print preparation in slicing program
The STL files, i.e. the 3D objects, are prepared for 3D printing in a so-called slicing program. This produces a code over the print pattern for the printer, here based on the customer's wishes for mechanical properties and needs for support during printing.
Step 3: Object printing via FDM or SLA
The objects are then printed either by fused deposition modeling (FDM) or stereolithography (SLA).
FDM is the most common method and prints by extruding material in a long 'string' that builds layer upon layer. FDM can use a wide range of materials: PLA, ABS, PET-G, etc.
Instead, SLA uses resin, which is a liquid material at room temperature. Resin also comes in various forms, e.g. medically approved, for contact with human mucosa. The printer uses UV to cure the resin in the desired pattern, producing one whole surface at a time. The 3D object is thus dipped in a layer of resin, then only the desired area is cured and the process continues until the whole element is finished.
Depending on the desired mechanical and biocompatibility properties, the objects are printed by FDM or SLA'.
