The release of the 2.6.0-alpha2 version of PrusaSlicer brings two new functions to the slicer that will be valuable additions to the photogrammetry workflow. Measurement tool The new measurement tool in PrusaSlicer 2.6.0-alpha2 "recognizes points (vertices), edges, circles and planes" and allows you to take measurements between these. Additionally, it allows you to pick a measurement and scale it – and the rest of the model along with it – to a desired length. Improvement for 3D scanning: A common nuisance with 3D models obtained through photogrammetry is that they do not turn out to scale. Th ..read more

tldr; Squidmar Miniatures released a great video, where they used the OpenScan Mini and the OpenScanCloud to scan one of their amazing miniatures. As the video is focusing on the results, I want to add some more technical details. Anway, the raw results already speak for themselves: If you haven't already seen it, please check out the entertaining video, where the same miniature got scanned and resin-printed again and again and again and ... https://www.youtube.com/watch?v=tp5p2nDnON8 Disclaimer: I provided a pre-build version of the OpenScan Mini free-of-charge, but besides a brief introduct ..read more

tldr; Till the end of September, you can get the new Arducam TOF camera on Kickstarter*, where you can now get the device for ~US$30 instead of US$50. What looks like a normal camera, is a depth sensor with a resolution of 240x180 pixel. This sensor is capable of capturing depth (3D) information with 30fps on a Raspberry Pi 4. Disclaimer: I got this sensor free of charge from Arducam. No money changed hands, and I am just doing some independent testing and evaluation. This post reflects my findings and opinion. An important note on Kickstarter and other Crowdfunding platforms: Before taking p ..read more

In my last blog I talked about the reasons for building an OpenScan classic with an RPi HQ camera. I also showed a bit of the increase in quality and sharpness of the scans. I sort of glossed over the whole project because I knew there was no way of including everything I want to talk about in one blog post while also keeping most of you reading until the end. That’s why, very early in writing the first blog post, I decided to make a series of articles. This is the second article, a deep dive in the pro’s and con’s of the 35 mm 1.6f Fujian lens!

tldr; I am comparing the OpenScan Mini with the Arudcam IMX519 to the OpenScan Classic with RPI HQ camera with regards to scanning very small parts in very high resolution. The IMX519 can not zoom, thus a lot of pixels seem wasted. With the right lens the HQ can get the small parts in focus and filling as much of the sensor as possible. This improves the mesh resolution, but at the cost of user friendliness and more expensive hardware. In a next article i will be looking at the relation between distance, aperture, focal range and much more! A few weeks ago, I built the OpenScan Mini, and I lov ..read more
