Lukas Renee-Cemmick is a Dorset, UK-based mechanical technician in the aerospace industry by day, and the rest of his time he spends designing and 3D printing with FFF-based 3D printers for his fledgling business ReneeCel Designs. This business has designed and printed a range of items, like gaming headset robust bracket replacements, print fed upgrade parts, bottle holders, ruler squires, water energizers, and a mini cross bow. He has made several designs available on Thingiverse.
One very impressive project that ReneeCel Designs has taken on recently is a 3D printed Water Jet Boat, which runs at an impressive speed with a propulsion system that it entirely 3D printed.
That’s right. Almost everything about this boat’s propulsion system is designed and 3D printed by ReneeCel Designs, including: the water jet impeller, the motor water cooling jacket, and all steering components. As Renee-Cemmick explains on his website, the initial idea was to “improve on the design of water jet boats.” So jet skis, high speed military prototype vessels, and search and rescue boats were all researched thoroughly. Once the boat hull was decided upon, the next steps were working everything together.
“The water jet system was then fitted to this (hull). 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,” he states.
In a YouTube video (see below) posted on July 4, we see the upgrading design process for the water jet’s next phase and the water jet boat in action.
Once again, I’ll say, as a person who lives in a Florida neighborhood surrounded by water and would love to see some of these boats out and about, the boat speed and maneuverability is quite impressive. Renee-Cemmick himself seems quite impressed by the boat’s performance in the video as well, as he states:
“Very good, so… all the tests: perfect! I need to do nothing… the boat’s really good. I don’t need to change anything, actually. It’s pretty fast. If I wanted it to go faster all I need to do is add another battery.”
He confirms in the video that for this version of the boat, the only thing that’s not 3D printed is the electronics, the battery, and the boat itself. The boat is powered by a Hobbywing 150 M speed controller and a 2045 KV motor.
Take a look for yourself at the video, but be warned. It will be hard for you to resist 3D printing one of these boats for yourself! You may also discuss this project in the 3D Printed Jet Boat forum thread on 3DPB.com.
