Scale up by 100 (or 1000) to make small parts For example, some plastics may require a wall thickness of less than 1 mm, while 3D printed ceramics require a minimum of 3 mm. The amount of the offset determines the wall thickness, and the thickness you need will vary depending on the material you are printing in. Here’s an example where Matt demonstrates modeling a vase with a 1/4” wall thickness using the offset tool.
Single faces in Sketchup have no thickness, so we need to simulate wall thickness by simply placing two faces a short distance apart. I’ll discuss how to determine what wall thickness to design at in just a bit. Wall thickness is a key element in 3D printing – walls need to be thick so they’re strong enough to work in real life, but also need to be minimized to reduce material costs. The most common errors (and the corresponding solutions) are: If an edge has less than two faces bordering it, there is an adjacent hole, and if there are more than two faces touching an edge, there is an extra face that needs to be deleted.
If you make your object into a group or component, Sketchup will indicate when its solid in the Entity Info dialog box (Window > Entity Info).Īnother way to define solid: Every edge in your model must be bordered by exactly two faces. If you were to fill it with water, none would drain out, and the model must not have any extra lines or faces. Solid, sometimes called “watertight” or “manifold” simply means the model is a complete enclosure. Here are some examples of Solid Sketchup models. This is by far the most common problem beginners have when modeling for 3D printing.
Models must be “Solid” to be 3D printable. Make your model “Solid” in Sketchup to be 3D Printable Here are some common problems that I see beginners struggling with and how to address them.ġ. The process of modeling for 3D printing is much the same as 3D modeling anything else, but with a few specific requirements. But how does one get started making awesome models for 3D printing? Its one thing to make a model look good on the screen, but quite another to make a model that looks good and actually works in real life.
