Using Onshape Loft and Shell – 3D Design for 3D Printing Pt3

Introduction to the tutorial

In this tutorial, we will be exploring the use of Onshape’s loft and shell tools for 3D design and printing. designing your own parts for 3D printing can greatly improve the quality of your prints and open up a world of possibilities. The loft tool allows us to join odd-shaped objects with smooth transitions, while the shell tool is used to hollow out solid bodies. We will demonstrate how these tools can be used to create heating and cooling ducts, as well as adaptors between different objects.

The importance of designing your own parts for 3D printing

Designing your own parts gives you full control over the functionality and aesthetics of your 3D prints. By creating custom designs, you can ensure that your parts fit perfectly and serve their intended purpose. This is especially important when it comes to creating ducts and adaptors, as these parts need to be precise in order to function properly. Using tools like Onshape’s loft and shell can help you achieve the desired results with accuracy and ease.

Demonstration of using lofts to join odd-shaped objects

The loft tool in Onshape allows you to seamlessly join two or more sketches with smooth transitions. This can be incredibly useful when working with odd-shaped objects that need to be combined. Even if the end profiles are different or face different directions, the loft tool can create a smooth connection between them. We will demonstrate this technique by creating a duct that joins two different end profiles in a clean and visually pleasing way.

Hollowing out the solid body using the shell tool

Once we have created the desired shape using the loft tool, we can further refine the design by hollowing out the solid body. The shell tool in Onshape allows us to remove material from the inside of the object, creating a hollow cavity. This is especially useful for creating ducts, as it reduces weight and allows for better airflow. We will show you how to use the shell tool effectively to create a hollowed-out duct with the desired dimensions.

Creating heating and cooling ducts using lofts and shells

Heating and cooling ducts play a crucial role in many applications, including 3D printing. By using lofts and shells, we can create custom ducts that efficiently direct airflow and regulate temperature. We will guide you through the process of designing and creating heating and cooling ducts using the loft and shell tools in Onshape. You will learn how to control the smoothness of transitions, set dimensions, and optimize the design for 3D printing.

Making adaptors between objects using lofts and shells

Adaptors are commonly used in various industries to connect different objects or systems. By using the loft and shell tools in Onshape, we can easily create adaptors that fit perfectly and bridge the gap between two objects. Whether you need to connect different-sized pipes, adapters for dust extraction systems, or simply create custom fittings, the loft and shell tools can help you achieve the desired result. We will demonstrate how to create adaptors using these tools and provide tips for designing for optimum functionality.

Covered topics in the video tutorial

During the video tutorial, we will cover various topics related to designing 3D prints using Onshape’s loft and shell tools. Some of the topics covered include taking accurate measurements using digital calipers, importing 3D models from external sources like GrabCAD, creating sketches to trace geometry and set dimensions, using custom planes for sketching on non-existent surfaces, controlling the smoothness of transitions with the loft tool, hollowing out parts with the shell tool, joining different parts using the boolean tool, considerations for 3D printing such as flat surfaces and material choice, and tips for lofting more complex shapes and multiple profiles.

Mention of other tools and techniques

In addition to the loft and shell tools, we will briefly mention other tools and techniques that can be useful in 3D design and printing. These include the derive tool for importing parts from other documents, the move face tool for adjusting the position of objects, and various considerations for 3D printing, such as support structures, infill patterns, and layer heights. We will provide an overview of these tools and techniques to give you a broader understanding of the possibilities within Onshape.

Recommendations for buying quality filament and resins

To ensure the best results in your 3D printing projects, it is important to use high-quality filament and resins. We will provide recommendations for reputable sources where you can purchase quality filament and resins. These sources offer a wide range of options for different types of printers and materials, ensuring that you have access to the best supplies for your projects.

Overview of the tutorial on creating 3D designs for 3D printing

In this tutorial, we focused on using Onshape’s loft and shell tools to create ducts and adaptors for 3D printing. We demonstrated how to create smooth transitions and odd end profiles using the loft tool, and how to hollow out the design using the shell tool. We discussed the importance of designing your own parts for 3D printing and provided recommendations for purchasing quality filament and resins. We covered various topics and techniques related to 3D design and printing, and encouraged you to continue learning and exploring new possibilities in Onshape.

To make the most of 3D printing, it is beneficial for you to be able to design your own parts. In this tutorial series, you will learn how to use a free 3D CAD program to accomplish this.

In this episode, we will utilize lofts to connect unconventional shapes and then hollow out the solid body. This technique is perfect for creating ducts for heating or cooling purposes, as well as making adaptors between different objects.
