3D printing used to make glass optical fiber preform

Posted on Updated on

According to Science News and John Canning who led the research team from the University of Technology in Sydney, “Making silica optical fiber involves the labor-intensive process of spinning tubes on a lathe, which requires the fiber’s core or cores to be precisely centered. With additive manufacturing, there’s no need for the fiber geometry to be centered. This removes one of the greatest limitations in fiber design and greatly reduces the cost of fiber manufacturing.
Additive manufacturing approaches such as 3D printing are well suited to change the entire approach to fiber design and purpose. This could, for example, broaden the applications of fiber optic sensors, which far outperform electronic equivalents in terms of longevity, calibration and maintenance but haven’t been widely deployed due to their expensive fabrication.”

Photogrammetry software for 3D Printing

Posted on Updated on

Photogrammetry software for 3D Printing. According to Sculpteo, “3D scanning could be useful for various applications. It can be used to get a viable 3D model and make the most of the 3D printing technology using an online 3D printing service such as Sculpteo. But having a great 3D design is also an amazing tool for visualization.

Photogrammetry is useful for topographic mapping, architecture, engineering, or even geology! There are a lot of software tools dedicated to aerial photos, photogrammetry is really useful for geographical use. For instance, archeologists are also using it to create plans for complex and remote sites”.

Some of the best free photogrammetry software


Agisoft PhotoScan
3DF Zephyr Free
Colmap
Visual SFM

Paid software

Context Capture
Reality Capture
3DF ZEPHYR
Autodesk ReCap Pro
Inpho
iWitnessPRO
Pix4Dmapper
Photomodeler Pro 5

According to some comments,
“It is still easier to 3D sculpt from scratch than to scan using photogrammetry in some cases. As some 3D sculpting will be needed when cleaning and patching anyway.
Zephyr offers a function where you can upload an mp4 / video file. Pretty cool feature. It does all the things in the video but in one tool. Much easier to use as well. Free is capped at 50 photos.
COLMAP is sooo cool and cheaper smarter alternatives.
Autodesk Recap is paid and limited (I heard that there is a limit number of the image you can upload to their cloud – and it’s the web-based application so if you don’t have internet, you can’t do anything).

Some people like VisualSFM and best software to do this is still pix4d. These are also powerful and free, it uses additional CSM tools you need to install for as dense reconstruction; it works great with different image sources.
3D Creator from Sony Xperia is really easy and awesome and avoid a lot of steps compared to this traditional method.
Agisoft Photoscan is far better than Colmap+ Meshlab.
For some problems, we can get suggestions from the comments.
I am trying to get into 3D computer modeling, and I want to model this new military helicopter for a video game (ARMA 3).
The problem is the chopper is extremely new and there are very few pics of it out there, so the background in each photo is always different. would these cause problems with modeling.
If you want to get some pretty amazing results using the basic version of Agisoft Photoscan ($179 US for a commercial license) and some very good results with VisualSFM (free for non-commercial use).
You can rotate the object as long as the background is in solid color. There are several solutions on the internet, mostly by programming Arduino to rotate turntable with the object, then sending remote shutter signal to the camera. This whole process can be automated with very good results:)
