MatterThings Hosts 3D Hubs & Sketchfab 3D Scanner Party
3D Hubs Mayors of Montreal (Quebec) Canada, MatterThings, hosted the 3D Hubs & Sketchfab 3D scanner party in their 3D print shop.
Event attendees that were curious about 3D scanning, were able to learn about and test various types of 3D scanners, apps and technologies. From Structure Sensor by Occipital, Scanify by Fuel3D, Xtion by Asus, Kinect by Microsoft, 123Catch by Autodesk, Trino and Digitizer by MakerBot. Scanning stations were set up inside MatterThings' 3D print shop so everyone had the opportunity to scan themselves, objects and one participant even tried scanning his kayak! For those that missed the event, you can learn more about 3D scanning below.
Also announced at the event was 3D Hubs' recent partnership and integration with Sketchfab, a platform that allows people to easily publish, find and share 3D Content. Sketchfab is for 3D scans what YouTube is for video.
How does 3D scanning work?
3D scanning is the digital capturing of the world around in it’s 3D dimensions. It’s also known as 3D reconstruction. The result or output of this process being a 3D file.
- Physical Object is scanned.
- Post Processing: Data is processed by the app to create a 3D mesh usually done in the cloud and automatically by a powerful computer.
- Digital File: the processing of the photos results in a created mesh, textured or not depending on the technique/hardware.
- The result can then be saved, exported and your 3D rendering is then ready for 3D printing.
Different 3D scanning technologies
There are many different types of scanning technologies:
- Infra Red or Structured Light Scanning.
- Photogrammetry is based on standard photography and projective geometry.
Photogrammetry is a technology based on standard photography and projective geometry. Originally used to digitize large objects such as buildings, oil rigs and warehouses. The principle behind photogrammetry is to take multiple images of objects and manually or automatically reference common points in each photograph. Points can be added automatically or manually to create 3D measurements of the desired elements of the part. Some examples are apps like 123D Catch, Trnio, Recap 360, Photoscan & Fueld3D.
The projection is done with a dedicated infrared laser projector. Projects a unique infrared pattern of dots The camera receives that image and uses dots to visualize shapes & distance of the objects. Some examples are: Kinect & Structure Sensor.
