Design and Build Process

Building a 3D printed RC sailboat involves the following steps:

Design Phase

  • Choose the right type of RC sailboat design
  • Create a 3D model of the boat using a 3D software like Fusion 360 or Tinkercad
  • Optimize the design for 3D printing by checking the design for potential errors and ensuring that it is watertight
    • Construction Phase

      • Select materials suitable for 3D printing the boat
      • Use a 3D printer to print the parts of the boat
      • Assemble the parts of the boat
      • Add electronics, such as a motor and servo, as necessary

      It is interesting to note that the use of Fused Deposition Modeling (FDM) printers is popular for 3D printing RC sailboats. This is because FDM printers can print objects that are water-resistant and durable.

      Before starting the print process, it is essential to choose the right filament material. Common materials used for 3D printing RC sailboats include PLA, ABS, Nylon, PETG, and TPU. PLA is a popular choice because of its ease of use, low cost, and eco-friendliness. On the other hand, Nylon is a very durable material that can withstand challenging sailing conditions.

      Part Material
      Hull ABS
      Deck PLA
      Mast PLA
      Bulb keel Nylon

What is the structure of a sailboat?

A sailboat is composed of several parts that work together to navigate through water. Below is a brief overview of the typical structure of a sailboat:

  • Hull – the main body of the boat, which provides buoyancy and stability
  • Deck – the uppermost surface of the boat, which provides a platform for crew members to move around on
  • Mast – a vertical pole that holds the sails aloft
  • Sails – large pieces of fabric that are attached to the mast and boom and catch the wind to propel the boat forward
  • Boom – a horizontal pole that holds the bottom of the mainsail
  • Rudder – a flat piece of metal or wood at the stern of the boat that is used to steer
  • Keel – a weighted fin that is attached to the bottom of the boat and helps keep it stable while sailing

Understanding the structure of a sailboat is crucial for sailing safety. If you’re interested in learning more about this topic, websites such as and offer useful information and resources. Additionally, products such as “The Annapolis Book of Seamanship” by John Rousmaniere provide a comprehensive guide to sailing and sailboat anatomy.

3D printed RC sailboats offer several advantages over traditional models. Some of these advantages include:

Lightweight Construction

  • 3D printing allows for lightweight construction, which improves the boat’s speed and maneuverability
  • Designers can optimize the weight distribution of the boat to achieve optimal performance

Design Flexibility

  • 3D printing enables designers to create complex geometries and designs that are not possible with traditional methods
  • Designers can create more aerodynamic and hydrodynamic shapes, leading to faster sailing speeds


  • With 3D printing, designers have complete control over the design and construction of the boat
  • Customization options are virtually endless, from hull shape to color scheme

Interestingly, a 3D printed RC sailboat designed by Gary Smith set the record for the fastest wind-powered boat in 2016, reaching a speed of 68.01 miles per hour. This demonstrates the potential that 3D printed RC sailboats have for high performance.

Several websites offer resources for anyone interested in building their own 3D-printed RC sailboat, including Thingiverse, Pinshape, and MyMiniFactory. These sites offer boat designs, 3D printing instructions, and other resources to help enthusiasts get started on their projects.

Can you 3D print a sailboat?

Yes, it is possible to 3D print a sailboat, however, it largely depends on the design and size of the sailboat.

  • 3D printing can be cost-effective and offer limitless possibilities for custom designs.
  • Large 3D printers are required for printing bigger scale boats.
  • 3D printing technology is still evolving, and its application in the marine industry is still limited.

Various companies like the Italian start-up Livrea Yachts have used 3D printing technology to create customized sailboats. However, it’s worth noting that traditional sailboat manufacturing methods are still the most commonly used.

There are numerous 3D printed RC sailboats that have gained popularity in recent years, including:

OpenRC Sailboat

  • Designed by Daniel Noree and featured on Thingiverse, the OpenRC Sailboat is a popular option for hobbyists
  • It features a sleek design, with a V-shaped hull and three triangular sails
  • The boat is customizable, with options for different material thicknesses depending on desired weight and durability

Ada Lovelace’s RC Sailboat

  • Engineering students at the University of Southampton recreated Ada Lovelace’s 1845 sailboat design using 3D printing and modern RC technology
  • The resulting boat was not only functional, but also historically significant

Little RC Yacht

  • Designed by MyRCCar, this boat features a classic yacht design with modern RC components
  • The boat is easy to assemble and can be printed in sections to fit smaller 3D printers

In addition to these designs, many hobbyists have successfully designed and built their own 3D printed RC sailboats. Online communities such as RC Groups and the 3D Printing subreddit offer resources and support for those interested in pursuing this hobby.

What is the most popular RC sailboat class?

The most popular RC sailboat class is the International One Metre (IOM) because of its affordability, ease of transportation, and competitive racing opportunities worldwide. Some of the benefits of IOM racing include:

  • A well-established class with a large and active community
  • An affordable price point for both building and purchasing ready-to-sail boats
  • Ease of transportation due to the smaller size of the boats compared to other classes
  • Opportunities to race competitively at local, national, and international levels

For more information about IOM racing, visit the International Radio Sailing Association website.

Maintenance and Repairs

Maintaining and repairing a 3D printed RC sailboat is similar to traditional RC sailboats, with a few key differences due to the materials used. Here are some tips to keep your 3D printed RC sailboat in top condition:

  • Use a low-strength filament for parts that require flexibility, such as sails or rigging
  • Inspect the boat regularly for cracks or damage, as 3D printed parts are more prone to breakage than traditional materials
  • Keep the boat dry and store it in a protective case to prevent warping
  • Use sandpaper or a file to smooth any rough edges or corners on printed parts
  • Replace parts as necessary, such as the sail or rigging, with 3D printed replacements

There are online resources available for 3D printed RC sailboat enthusiasts to purchase replacement parts or upgrades to their boat. Many hobbyists offer 3D printed parts for sale on websites such as Etsy and Ebay. Some sites also offer free designs for 3D printed RC sailboat parts, such as Thingiverse and MyMiniFactory.
