Not only does increasing the wall thickness strengthen the printed material, but it also improves overhangs (geometry shapes in 3D models that are difficult to print) and water tightness. Increasing wall thickness will increase strength as 3D printed parts have more strain on the outside than the inside. The wall thickness of a 3D printed material is measured by “Wall Line Count” and “Outer Line Width.” It shows how thick the wall and increasing it is a critical way to make strong 3D prints. Note: Have at least a 20% infill density for strength and, if possible, tweak the wall thickness (explained below) before increasing the infill density. Instead, there is a tremendous increase in filament use, printing time, cost, and burden on the 3D printer. However, practically most designers have noticed that anything beyond 70% has a lesser impact on strengthening the 3D print. Theoretically, having a 100 infill density should make your 3D print very strong. The interior density ranges from 0% to 100%, with zero means totally hollow while 100 means totally solid. One way of increasing the strength of a 3D print is by increasing the interior density. Below are how to make strong 3D prints using them. There are many settings on your 3D printer that you can tweak for a high-quality and strong print. However, unless you are deeply into 3D printing with knowledge surrounding its use, you might have a little trouble making a strong 3D print. Having a 3D printer for your personal works is more efficient and effective in personal product manufacture. Go through a simplified version of how to make 3D printed parts strong. If you want to outsource your projects, you will get information about different materials and recent post-processing technologies that will give you an idea of how to communicate to the prototyping service better. If you have a personal 3D printer, you will learn how to tweak the settings to achieve the best results. This article will provide details on how to make strong 3D prints and it is helpful for those either have a personal 3D printer or want to outsource to rapid prototyping services. In terms of improving the strength of 3D printed parts, there are many things that come to play. 3D printing is a popular manufacturing process with wide acceptance because of the quality it delivers. Structural integrity in 3D printing is important as 3D prints must not collapse while functioning.
