To have a good chance at getting a high-quality result from your 3D printer, you need your first layer to be perfect. There are a number of things you can do to help this or to make it worse. The most basic requirement is to have a properly levelled print bed. You can, however, face issues if you add something to the bed after you’ve calibrated it. If you add a sheet of … [Read more...] about 3D Printing Basics: Z-offset
3D printing is a cool way to create real-world replicas of 3D computer models. There are several different ways to do so in your own home. FDM printing with thermoplastics and MSLA printing with photosensitive resins are both relatively affordable and easy to buy. There are other, more exotic methods of 3D printing that can offer unique advantages. Unfortunately, these are much … [Read more...] about What is Cold Spray Metal 3D Printing?
Everyone familiar with FDM 3D printing knows about layer lines. They’re an almost ever-present menace, limiting the final quality of all prints. Unfortunately, this isn’t the only downside of the additive manufacturing approach. At the start and end of each layer, the plastic simply can’t be smoothed together, leaving a visible seam. Depending on your slicer settings, this can … [Read more...] about 3D Printing Basics: What Is Z-Seam?
One of the ever-present features of 3D printing, especially FDM, is layer lines. Because the size of the printed plastic is still visibly large, very little can be done to minimize this. Even when using the smallest layer sizes available, layer lines are visible. They’re also noticeable on flat surfaces such as the top of the print. Interestingly, there is something that can be … [Read more...] about 3D Printing Basics: What is Top Surface Ironing?

There are also applications for which 3D printing can struggle, at least with common materials and processes. One of these applications is threaded parts. When talking about threaded parts, most people will think of screws or … [Read more...] about 3D Printing Basics: Printing Threaded Parts
Any 3D printable that you print will have some level of inaccuracy compared to the 3D model on the computer. This inaccuracy is called tolerance and is a feature present in all forms of manufacturing. In some fields, this tolerance needs to be particularly fine. For example, in the watchmaking industry, the tolerances on each component are tiny. … [Read more...] about 3D Printing Basics: Improving Dimensional Accuracy
