When it comes to 3D printing, achieving that perfect part is the ultimate goal. However, the journey to perfection involves a variety of settings and adjustments. In this guide, we’ll explore one of the most crucial aspects of 3D printing: speed.
The Need for Speed
The speed setting in your 3D printer controls how fast the nozzle moves around the part, laying down each layer. Naturally, we all want our 3D prints completed as quickly as possible, but there’s a catch. Faster speeds can sometimes compromise the quality of your prints.
High-quality 3D printing is often associated with slower speeds. The reason behind this lies in the mechanics of 3D printing. Imagine your 3D printer’s nozzle rapidly moving from one point to another. The faster it goes, the jerkier the movements, and this can lead to issues with the final print’s quality.
High speeds mean more momentum to control, and if your printer uses belts and splines, maintaining precision becomes challenging. On the other hand, slower speeds result in smoother, more accurate curves and details. Therefore, it’s essential to strike a balance between speed and quality based on your project’s requirements.
The Speed-Quality Trade-Off
Deciding on the right speed setting is a trade-off between quality and efficiency. If you need a functional part quickly and aesthetics are not your top priority, higher speeds may be acceptable. However, for projects that demand perfection, opting for slower speeds is the way to go, provided you have the luxury of time.
Many factors influence your speed choice, but one of the critical ones is the material you’re using. Different materials have different optimal print speeds. For instance, common materials like PLA usually print at speeds of around 60 millimeters per second (mm/s) on most machines.
That said, the world of 3D printing is dynamic, and experimentation is ongoing. Some enthusiasts are pushing the boundaries and achieving speeds of 100 mm/s or even 150 mm/s, but this often requires specialized hardware and precise settings.
As of March 2019, standard 3D printing speeds typically range between 40 mm/s and 100 mm/s. The hardware landscape may evolve, leading to changes in these numbers, but it serves as a good reference point.
Finding the Right Speed for Your Project
For beginners, starting with a speed of around 40 mm/s is a safe bet. You can gradually increase it to 60 mm/s for common materials without sacrificing too much quality. As you become more experienced, you’ll discover the perfect speed settings for your specific projects and materials.
Keep in mind that advanced materials, especially high-temperature ones like PEEK and PEI, often involve different speed ranges based on the part’s geometry. For instance, vase mode and solid block settings will differ.
Whether you’re working with a $300 3D printer or a $30,000 high-end machine, the key to achieving great results remains consistent: it’s all about selecting the right material and tuning your printer to perfection.
