Segment:1 An interview with Dietmar W Hutmacher (Queensland University of Technology, Australia).
[MUSIC PLAYING]
DIETMAR HUTMACHER: My name is Dietmar Hutmacher. I'm a chair in regenerative medicine at the Queensland University of Technology and I'm also a Director of the Australian Research Council (ARC) Centre in Additive Biomanufacturing. So in my ARC center, we use a lot of 3D printing to design models for patient-specific cases. We actually also develop 3D printing technologies, we develop biomaterials and we also work very closely with surgeons on implant design.
Segment:2 Using 3D printing in the medical field.
DIETMAR HUTMACHER: The biggest interest I have in using 3D printing in the medical field is that it is a very versatile technology which can help us on different levels to support clinicians which are treating the patient, and then obviously it is very rewarding to see that some of your work you do actually helps a patient to have a better outcome. So the way we use the technology and the way I see the great benefits is, again, in presenting preoperative planning tools for the surgeons, then using these preoperative planning tools also to design, for example, specific templates to give the surgeon landmarks inside the body where he has no directions how to cut tissues, how to cut bones, and so on. And then finally, I think the holy grail is that you then 3D print implants, which are based on the design where you used 3D printing models to come up with the optimal design for the patient.
Segment:3 Multidisciplinary approaches to 3D printing in surgery.
DIETMAR HUTMACHER: What 3D printing technology offers to what I would call an interdisciplinary team, because it's not just supporting the surgeon, but it's the support of the entire team which is working on the patient, which can be sometimes quite large is to - or let's say, starting with the surgeon. We get a lot of feedback, especially the tactility of the models helps the surgeons a lot in their perception in practicing the surgery. The other very important aspect is surgeons obviously always have to think about 3D, but when they plan surgeries on the computer, even though you see on the computer a 3D image, it is still 2D. So the perception of the surgeon, again, having a model in front of him and not just only touching it, but looking into it is very different than looking onto a computer screen and getting much more of that feeling as they would have in a patient about this 3D space. So that is a great benefit. Again, the other important aspect is that, for example, the operation nurse, if she goes with the surgeon through their training on a model, that this is much more smooth in respect to that she would know much better which type of instruments the surgeons would use at which stage of the procedure. So there are many benefits of this technology.
Segment:4 Melt electrospinning technology: 'taming the jet'.
DIETMAR HUTMACHER: The melt electrowriting technology is a 3D printing technology which we are very excited about and where we have been doing a lot of work over the last 10 years. It is also a very complex technology. Hence, the title of the paper "To tame the jet." So we have done over the years the fundamental work to find out what are the most important processing parameters one needs to control to tame the jet. We also have worked on the improvement of the hardware as well as on the software. So what this technology allows us to do is now to go down to a resolution at least down at the moment to a micron. We think in the next 5–8 years we will be able to push this down to the nanometer range, so below 100 nanometers. And the excitement is but even so we go down to 100 nanometers that we have full control where the fiber is laid down. So we can really design and then fabricate very complex implants and structures. And that is very exciting for this technology to come.
Segment:5 The operating room of the future.
DIETMAR HUTMACHER: The aspects in the next 5 years where the 3D printing technology will be embedded in a hospital infrastructure is enormous. I mean, we have seen this already that there are a number of hospitals, which are using this on a day by day basis. These are generally very large hospitals, which already have a infrastructure where the innovation plays a major part. So I think what will be important in the future is that we make this technology available for smaller hospitals, for hospitals, which really are looking after the patient on a basis that they don't get the very complex cases all the time. As the hospitals which are using at the moment the 3D printing technologies, they get very special cases, which are referred to them. I think one of the big challenges for us is to make this technology so accessible, to simplify it that even small, regional hospitals for the standard care of their patients can use this as tools, use this technology to benefit their patients in the future.
