PROJECTS WE HAVE UNDERTAKEN
How it began
We want to see what can be achieved with 3D printing and a cross bow is demanding tool so we started work.
We started by designing the firing mechanism, which has to be strong and very reliable. We sketched some basic ideas and researched Leonardo Da Vince's drawings of giant cross bows for reference.
Once we were satisfied with the firing mechanism we moved onto the cross bow it's self. Strength was a major concern, so time was taken to carefully constructing a light but strong design.
Mini Cross Bow
This Mini Cross Bow is both compact and light weight.
It comprises of an impressive carbon fibre bow that is more than capable of pest control. There is also a hidden Bolt storage in the handle.
When the design was finished we printed it out. It's very hard to actually tell whether something will work as you expect, sometimes you just have to try things before you know they are going to work.
Water Jet RC Boat
This small RC Water Jet Boat was fully 3D printed. Everything down to the water jet impeller, motor water cooling jacket and steering components have been 3D printed.
What was the inspiration
We started looking into water jet boat and their huge potential. This type of water craft are very efficient at high speeds and have unprecedented maneuverability.
We wanted to try and improved on the design of water jet boats. So lots of reasurch into different water jet boat types was conducted, ranging from jet skis to huge high speed military prototype vessels and search and rescue boats.
We didn’t was to redesign a hull so one was downloaded from Thingiverse. The water jet system was then fitted to this. After waterproofing and numerous improvements to the electrics we went for a test run. The first test was in the sea, so everything had to go smoothly. Our hard work paid off as the boat shot along in the wavy water. We really want to go further and look at other water jet propulsion uses.
3D printed Water Jet Boat
This full scale RC Water Jet Boat was fully 3D printed. Everything down to the water jet impeller, motor water cooling jacket and steering components have been 3D printed.
Powered by a 2.5hp brushless motor running on 11.1v lipo batteries, the water jet system will pump almost 3 Leters/per second! thats 3kg per second of thrust.
Appart from being one of the first 3d printed boats its most deffinetly the fastest about speeds of up to 40mph running on 22.2volts. Parts can be purchased on shapways!
