Since PP’s inception over a year ago we have strived to make the most out of 3d. Creating 3d models from scratch, adjusting CAD files from clients, painting & assembling fantastic and one of a kind items. But this wasn’t enough… we were missing something, something that let us make the ultimate personalisation… until now.
The FARO design ScanArm has really helped propel us to dizzy new heights in personalised creation – giving us a kick up the behind to learn some of the more complicated functions in our CAD software…Rhino/Grasshopper for those interested.
We’ve been able to take organic shapes (such as a hand or foot) and capture the surface to create the exact template we need to model around – chucking in random (or not so random) geometries and shapes in a controlled manner.
Below is a quick synopsis on how we did it:
Quick scan & data manipulation
It helps when you are using the smartest piece of kit on the market right now (well we think so).
The ScanArm is able to capture high-resolution data at breakneck speed, picking up as much as 500,000 points / second. For this exercise we didn’t need that amount of data so we scaled it back – you’ll thank yourself for doing this when it comes to manipulate the data later!
Once we have the initial data we need to play with it until we had only the bits we need. We did this by cutting using a planar surface and capping the ends, we can also remove the erroneous data that is always picked up by the scanner.
Now we’re left with a smaller section of the arm we want to make life easier when we model, so we should convert the point cloud into a mesh, then into a surface. We then draw lines along the surface to further reduce the profile to the bracelet we want to work with – creating a smooth patched grid before importing to Rhino.
3D Modelling in Rhinoceros
Now that we’ve imported a clean surface into Rhino we can really start working some magic using paneling tools, or if you are really adventurous you could start coding your geometry using the Grasshopper plug-in. For this quick example we used the paneling plugin for Rhino.
Using our surface we created a paneling grid, specifying how many points should occur along the U & V. (( 5 x 5) x 3) for our example. Using the offset points grid utility we then created a second group of points 2cm out from the original.
These 2 sets of grid points are then used to create a 3d custom panel, using some simple geometry we whipped up earlier. This function arrays the geometry 5 times along the U and 15 times along the V.
We now have some lovely geometry arrayed around the exact fit of the person we scanned – a clever way to create the ultimate personalised bracelet!!
The best news is it took less than a day to model & print!
So what next?
We’re looking at taking customisation to the next level.
No more standard out of the packet designs, created a million miles away in a massive factory you’ve never even heard of.
We are talking about unique designs, personally tailored and created for individuals just like you. This was a very simple run through but the crucial message is that the possibilities to create individual designs on a larger scale are arriving.
