3d printing

Hello all, Karl here. I just wanted to send a note about what I have been working on. As the title says shows it is about 3d scanning. I have found it pretty fascinating so far. These are mainly based on structured light 3d scanning. From Wikipedia: Structured light is the process of projecting a known pattern (often grids or horizontal bars) on to a scene. The way that these deform when striking surfaces allows vision systems to calculate the depth and surface information of the objects in the scene, as used in structured light 3D scanners. There are a few commercial offerings that I have run across or have found while searching around but they are very expensive. The first one I ran across was made by Einscan. They are over 1k and have been reviewed a lot. It seems like they put out a good product and keep […]

Hello CNX readers. Karl here. I am looking for some inspiration on a practical project to design and print from scratch. I am hoping someone might come up with an idea. I will share on Thingiverse, and I will ship it to you if you live in the continental United States. I will only do the plastic part. For example I just finished a bench power supply from an old PC power supply with the standard voltages and variable one from 2 to 30 volts. This has been done a million times already so just did it for personal use. It will be designed in Fusion 360. I can screen capture the build process, and speed up and put on YouTube if interested. Leave feedback in the comments below. Thank you for your help. Karl JohnsonKarl is a technology enthusiast that contributes reviews of TV boxes, 3D printers, and other […]

My keyboard is working fine. Thanks for caring. 3D printing has taken off in recent years, but if you plan to copy an object, you’d have to reproduce it in digital form in AutoCAD or other program, which may be difficult and time consuming. An obvious solution is 3D scanning, and I initially thought that 3-in-1 3D printers that scan print, scan, and copy object would really bring such products into more household, so I wrote about somewhat affordable printers such as AIO Robotics Zeus or Blacksmith Genesis, that would sell for $2,200 and up. The company doing the latter appears to have closed business, and the Zeus is still for sale but some users reported various issues with 3D printing. So if you’d rather not put all your eggs into one basket, it may be smart to purchase a 3D printer and a 3D scanner separately. The price range […]
