4 Important Reasons to Choose Threaded Rods for 3D Printers
Threaded rods are suitable components in 3D printing applications. In this application, the rod is basically utilized to create the Z-axis, and function as the printer drive mechanism. There have been many arguments put forth that leadscrews are a better option than threaded rods in 3D printing applications. While both products have their own share of advantages and disadvantages, there are certain reasons why the threaded rod is generally the first choice for this particular application.Understanding the Requirements of 3D Printing Applications
Before we get into the reasons for choosing threaded rods, we need to take a look at two important aspects that have to be considered for 3D printing â€“ accuracy and repeatability. The printer needs to provide accuracy in printing pages, and also needs to repeat the same task multiple times. This is where the importance of the threaded rod comes in.Benefits of Threaded Rods in 3D Printing
Now, let us take a look at the various reasons why the threaded rod is a popular component for 3D printing applications.
1. Tension in Application: Threaded rods are known for their satisfactory performance in linear motion applications like 3D printers. One reason behind this is that a certain amount of tension is applied to the rod during the printing operation. This ensures that the rod does not suffer from compression and bending during the printing process.
Many manufacturers produce smooth rods with large diameters to ensure that there is adequate tension, tensile strength and low levels of compression.
2. Movement Accuracy: In 3D printers, the rods are turned so that the printer mechanism moves and effectively scans the document in order to create a soft or hard copy. The threaded rods are manufactured at certain pitches, which enable the rod to provide a high level of accuracy in the printing / scanning process.
3. Adjustability: Sometimes, due to the manufacturing process, threaded rods can have a natural bend to them. However, this can be eliminated by creating high strength rods, which can provide stability in the application. Another option is to use precision linear motion mechanics to support the rod. Hence, the rod can be adjusted to suit the printerâ€™s requirements.
4. General Advantages: Threaded rods also provide a variety of general benefits to the application:
- The threaded rods need not necessarily be made of metal. They can also be manufactured from high grade plastic or nylon materials.
- Such alternative materials provide benefits such as lighter weights, high strength, and corrosion resistance.
These reasons enhance the popularity of threaded rods as the first choice for drive components in 3D printer applications.
