Since playing around with some 3D printed Virtual Reality headsets recently (previous post here) I’ve been interested to see how easily a 3D scan can be used to create a perfect-fitting headset. One of my biggest problems with the designs out there is that they’re pretty uncomfortable, especially if you’ve got a big European nose like me! One of the true benefits of 3D printing is the opportunity to customise a design, and 3D scanning fits perfectly within a designers workflow to do this. While the most accurate scanning technology may not be readily accessible to most people yet, it’s certainly not far off with a multitude of Apps and kickstarter projects hitting the market, so I’m interested to experiment with what can be done.
Thanks to the legendary Chris Little, aka. Golden Boy, who scanned my face using a handheld photogrammetry-type 3D scanner and spent a fun weekend processing the data, I now have a digital surface of my face to build 3D models with (image 1). In order to test how accurate this scan is to my actual face, I quickly modeled a part that mimics a simple virtual reality headset and 3D printed half of it on my Up! Plus 2 3D printer. Perfect fit! This means that not only will 3D models fit my face, but I can accurately measure things like the distance between my pupils and account for this in the placement of lenses within the design… All exciting things to come!
