There are different ways of doing this with hand-held scanners to booths in which a subject sits or stands in either a static chair or a turntable. By melting plastiline and pouring this inside the negative mould taken from the person, a positive version can be made which can easily be sculpted and modified once the plastiline has cooled and returned to a solid state.Īn alternative to lifecasting is to take an accurate 3D scan. where it would be a lot more effort to sculpt a lifelike portrait when an accurate lifecast can be made in twenty minutes. ![]() This is often the case for severed heads etc. I simply cleaned up the cast, opened the eyes and added some gory neck stump textures to create the severed head. The original headcast was done by Kristyan, who then filled the alginate cast with melted plastiline. ![]() This severed head was for a TV production of Dracula, for Kristyan Mallet. It can also be used to make bodies or body parts which are accurate to the performer without sculpting it from scratch. Usually you do this because you need a copy of the performer in order to make a custom fitting prosthetic which needs to fit them exactly. Lifecasting is making a three dimensional duplicate of a real body part, usually a face or head, of a live person. What is a lifecast and why do you need one If you want to check out a little lifecasting to whet your appetite, take a look at some videos of a face and hand cast I made with artist and well known makeup tutorial YouTuber, Klaire De Lys a while back: A great example is Lifecasting with Silicones and Alginates by Neill Gorton, available as a DVD and stream which pretty much covers everything in great detail! Rather than reinvent the wheel, we thought sharing our tips and tricks to build on the information available would be beneficial to you life casters at large! This won’t be an exhaustive tutorial on lifecasting, as this has been covered so well by others in great detail. We had a couple of questions regarding lifecasting, and seeing as there are as many techniques and variations as there are people taking lifecasts that it would be cool to bring together some of the best tips and tricks picked up from working with others. Scroll down to the bottom to hear the latest podcast on this. ![]() Errors made at this stage get passed on throughout each process. Often it’s the first process before work begins in earnest, so it’s really a good idea to do it well. To make one of these, you’ll need a 3D scanner and a copy of Meshmixer and Rhino 3D software, with Grasshopper, the algorithmic modeling plugin installed.Lifecasting is a basic, essential skill in creating custom fitted prosthetics. I’ve previously blogged on how to create Wrist Braces using Meshmixer, this method is more complex but has a better result and a better fit. This method is a DIY solution for experimentation only. A standard 3D print of a wrist cast takes about 3 hours to print on a 3D printer, where plaster tends to take about half an hour to fit to a patient and is very cost effective. ![]() While this is a great potential solution, 3D modelling and 3D printing a custom cast or brace is time consuming. However, if you normally wear a wrist split/other brace for injury you could create your own custom version of this with approval from your occupational therapist or specialist. This method is obviously not medically approved (as yet) and shouldn’t be used in place of seeing your doctor. Custom 3D printed casts made with a breathable, voronoi pattern are a potential DIY solution. This can create discomfort and skin problems for the patient during the healing process, like itchiness, rashes and skin infections. Traditionally, casts for broken bones are made from heavy, solid, non-breathable plaster.
