Boats have been in the use of human societies for centuries. They are used in the coastal regions and towns across the world like Amsterdam and Venice. Boats can take people from one point to another and for activities like obtaining data on marine biology and catching fish, a vital source of food. Building boats is a long and dreary process. Boats vary in how they are built, size, and the type of material used. They come in all forms and shapes. The building material also varies, from wood to fiberglass to metal. A boat could take from a week up to months to make with traditional methods. 3D printing aims to disrupt the conventional approaches and revolutionize the boat building. This article will look at the developments in 3D printing and boat building and some of the prominent projects.

Advantages of 3D Printing Boats

The creation of boats with 3D printing has many advantages. Traditional boat-making dates back to medieval times, and new production methods have emerged at different times in history. From manual craftsmanship and labor to automatic processing, creators can manufacture boats in unique ways. Thanks to 3D printing, the creation of vessels has become convenient and without loss of material. Furthermore, the capability of customizing and replacing parts has never been any easier. These are the general benefits of 3D printing boats. Let’s take a look at them in detail:

Less Material Waste

Additive manufacturing has one significant advantage over traditional production methods; it does not produce waste. Only the amount of material needed to build the ship is used without creating any excessive debris. Furthermore, other printing projects can use the surplus material. Traditional subtractive production methods waste the material, making production less environmentally friendly and more expensive.

Customization of Boats

Depending on the intended purpose, a boat can pack different features. Some models focus on speed while others on balance. 3D printing can be used to create unique models and produce parts for boats that can optimize its overall performance. For example, it can be utilized to develop an efficient and light-weight structure. 3D printing is also inexpensive, and it does not involve any additional costs. With traditional production methods, the process could be costly. The possibilities of personalization and customization are unparalleled when it comes to 3D printing.

Light-Weight Boats

Using 3D printing to make boats also helps significantly reduce the structure’s weight instead of traditional production methods. This means that the materials used in additive manufacturing are more straightforward, and the 3D printers use less material. If a boat weighs less, it can run better, be faster, and more durable.

Quick Parts Replacement

Water can be harsh and unforgivable for ships and boats. This harshness often results in damage to parts or shocks to the hull of the ship. Ship hulls often get clogged and jammed with debris, which can make cleaning them almost impossible or costly. So, it makes more sense to replace them. Damaged or dull ship hulls lose speed or performance. Thanks to 3D printing, parts can be easily replaced or fixed at a lower cost than completely replacing a hull.

Some maritime initiatives are working to improve the boat parts and their texture using 3D printing for better performance. They have found that texture improves not only functionality but also the perception of part quality.

The Largest 3D Printed Boat in the World

Using the world’s largest 3D polymer printer prototype, a team from the UMaine built the world’s largest 3D printed boat, which also proved to be the world’s largest solid 3D printed item. The UMaine Center of Excellence and Composites presented the 3D printed boat in a ceremony with the Guinness Book of Records representatives to certify that the group had set three new records.

At the end of the event, the crew tested the navigability of their 25-meter, 5,000-pound ship, called 3Dirigo, at UMaine Alfonda W2’s Ocean Engineering Laboratory, which has a multi-directional wave basin and a mighty wind turbine.

SkelETHon Concrete Kayak

Every couple of years, there are boat races on the Rhine in Cologne, Germany. This is an international competition in which teams of concrete canoe manufacturers from all across Europe participate. What distinguishes the competition in 2017 from all others is the commitment of the Swedish squad SkelETHon, which took first place in the “Innovative Design” category. They won thanks to their groundbreaking use of 3D printing to create a concrete canoe.

It was made of steel fiber that was reinforced with concrete. They used topology and form optimization to construct a skeleton. Once the structure was designed, the texture added to the internal beams allowed the use of a self-adhesive concrete coating to complete the build. This design was printed in 3D on a MakerBot printer as a hollow mold consisting of several dozens of individual pieces that form the ship’s frame.

The parts were then carefully glued and injected with a concrete mass in empty spaces. They buried the entire model in heavy sand so that the concrete’s weight does not compromise the structure. After it was cured, they dug plastic cover plates and removed them, leaving behind the concrete boat’s skeleton.

Impeller Boat RC

This is an RC boat that could easily be 3D printed. It can be printed in two parts: 162.5 mm (stern) and 163.5 mm (bow) high. It is also equipped with a steering wheel and a steering wheel.

3D Printed Fish Finding Boat

This boat can be used to find fish using sonar, as well as drop bait or hooks. It can help you fish in places where no one else can fish.

3D Printed Kayak

This fully 3D printed kayak is the first kayak in the world that was created with 3D printing. The kayak’s length is 5.08 m. The 28 structural parts of the kayak are 3D printed, fixed with M5 screws and threaded brass inserts, and then compressed with a small amount of silicone sealant. It is a fully functional kayak that floats really well.
