Week 3 - 3D Printing the Unmachinable and Scanning the World

Posted by Jordan Kennedy on October 3, 2017


1. 3D Print the Unmachinable

Or maybe not unmachinable but very difficult to machine.

Fortunately, I’ve done a lot of 3D printing previously and am well aware of many of the downfalls given that I’ve made a good deal of them at least one.

I’m printing this part with my final project in mind: The Gold Fish Race Track.

Shown here a valve for my Gold Fish race track in order to control the flow.

This is a part within a part. The outercase rotates about the center. This controls the surface area of the valve.

The valve has a thread to connect to a purchased piping.

Here is the 3D printed piece.

Revisited 3D Print I needed to modify the inlet 3D print for my final project resivour.

I wanted to train a laminar flow system. This is commonly done by flowing water through packed straws. So I 3D printed an inlet valve with straw like dimensions to train my water flow to be laminar.

The printed outlet valve can be seen below.





2: Scan and Render in 3D

To get these images I flew drones over beaver damming sites in northwestern Montana.

The drones flown were a DJI Phantom and a Parrot Bebop Drone.



The drones outputed MP4 video which I then converted into JPG files.

I used these JPG images and inputed them into Agisoft Photoscan. This is NOT a user friendly software.

  1. Unique JPG images were loaded into the software.


  1. Photo’s were aligned.


  1. The aligned photos were then meshed.


  1. Texture was applied to the resulting texture.


Show here is the full rendering. It consists of 548 unique photos and represents an area approximately 1/2 mile long. Completed

Shown here are Batches consisting of 16 photos each. These batches are then combined for the final rending. The final rending has around 16 batches.

Batch 2


Shown below is the raw processing data required to make the completed rendering.
