My user story with Revopoint:
Scanning starts and ends with a Pop!
I’ve always been fascinated with 3d scanning and have played around with photogrammetry on and off for years. When the original Pop appeared on Kickstarter I backed it because it seemed like a cheap way to get scanning. The Pop was rough around the edges and the software was lacking oh so many features but it was fun to use and frustrating in equal measure. I made lots of scans that looked like Star-Trek transporter malfunctions but I learned how things work, what can and can’t be scanned, and how to approach things.
Time went on and I started using 3d scanning as an integral part of my workflow. I needed something better than the Pop so I bought an Einscan SE. This was a very impressive product. Very limited, big, heavy, and slow but I got really good results with it. This was my workhorse for a few years and the benchmark I measured all future scanners against.
Fast forward to the Pop2 Kickstarter and I jumped on it right away. Much improved hardware and the software was getting better all the time. It didn’t replace my Einscan but was used alongside it as another tool in the kit bag for when lugging a 5kg scanner around wasn’t an option.
Mini was announced and I once again backed it on Kickstarter. Now we’re at the point where my Einscan is getting used less and less. Mini opened up new possibilities for reverse engineering for me, being able to capture details I previously didn’t think possible unless using $10k+ hardware.
Range arrived and was backed as usual. I use this one less but it’s still useful. Fantastic for scanning big stuff that I need to fit small stuff to.
Here’s a scan of one of the panels of my back door. I had a cat-flap in it that I needed to replace and wanted to design something that would fit perfectly.
I made a cover that aligns with it:
Then the biggest upgrade of the lot happened. Revoscan 5. What a difference. My Einscan was sold and I went all-in on Revopoint. The software now matched the hardware for quality.
Pop3 is my current workhorse. Fantastic product that it is. It sits alongside my other Revopoint scanners on the shelf of scanning stuff next to my workstation.
So, how do I use scanners? Well, mainly its for reverse engineering. If I need to make something that fits to something-else, it’s a massive time saver to scan the something-else and then model it in CAD rather than mess around with calipers and trial and error.
So, after that Giant Wall of Text crits you for 18,436 damage, let’s move on to workflow.
I start with a scan of an object, for example, here is a battery for a power-tool:
I want to make that battery fit in to the place for these batteries:
So, I get the scan in to Fusion 360 and start with a section sketch:
And gradually start adding curves and lines to build up a basic shape of the object:
I can then extrude those shapes to make a rough object of the correct dimentions:
After a bit of tidying and using the scan as a reference, we end up with a decent CAD model:
Next, we do the same for the original battery, import the scan and start doing section sketches:
I can then eventually design something that fits exactly to the model:
And finally, after many hours we end up with a finished product:
This is a very condenced overview of my workflow as there are lots of “Oh dear, that doesn’t work” moments but I get there in the end.
I’m very much a journeyman CAD person and scanner operator. I do this for fun and because I’m fascinated by manufacturing and product design. I love to learn and the Revopoint scanners have helped my take my designs to the next level.
I hope this post shows what can be done when you have a Revopoint scanner in your kit-bag.
