ADDING the MINI LATHE DEBRIS COVERS: A TUTORIAL

MATERIAL REQUIREMENTS FOR 3D PRINTS

When it comes to 3D printing, choosing the right materials can make all the difference in ensuring a safe and successful print. In this article, we’ll discuss the material requirements for three critical components: the Thread Cover, Side Cover, and Back Plate Cover.

TPU or Equivalent Flexible Material is Necessary

All three components require TPU (Thermoplastic Polyurethane) or an equivalent flexible material to be printed with. This is essential for safety reasons, as it allows the parts to flex and absorb any impact or movement without breaking off. In particular, this flexibility is crucial in catching debris and preventing damage to the surrounding machinery.

Printing Specifications

The following printing settings have been used in the examples within this document:

• Layer Height: 0.2 mm
• Infill Density: Minimum 15%
• Wall Lines: Minimum 3

These specifications are critical for ensuring a strong and reliable print that can withstand regular use.

Thread Cover Requirements

The Thread Cover is an essential component that must be printed with TPU or equivalent flexible material to ensure its intended safety feature. The printing specifications remain the same as above:

• Layer Height: 0.2 mm
• Infill Density: Minimum 15%
• Wall Lines: Minimum 3

When installing the Thread Cover, it’s essential to note that it fits snugly around the cross slider by stretching into place. Two inset components help secure the cover in position, ensuring a stable fit.

Side Cover Requirements

The Side Cover is another critical component that must be printed with TPU or equivalent flexible material. The printing specifications remain the same as above:

• Layer Height: 0.2 mm
• Infill Density: Minimum 15%
• Wall Lines: Minimum 3

When installing the Side Cover, ensure that you have assembled it in the correct orientation with the Thread Cover in place. This will allow for easy verification of proper assembly.

Back Plate Cover Requirements

The Back Plate Cover is designed to attach to and be supported by T-slots within the extrusion. It serves two primary purposes:

• Motor Vent Protection: The part shields the motor vent from potential debris or damage.
• Stock Material Containment: It also captures any material flying off during the lathing process.

The printing specifications remain the same as above:

• Layer Height: 0.2 mm
• Infill Density: Minimum 15%
• Wall Lines: Minimum 3

Additionally, the Back Plate Cover is designed to be removable for easier maintenance access.

Machine Requirements

For this tutorial, we used a ZHRUI metal miniature lathe (36W, 20000rpm), which was advertised on Amazon. It’s essential to ensure that you have a similar machine in place before attempting these modifications.

By following the material requirements outlined above and using the correct printing specifications, you can ensure that your 3D prints are safe, reliable, and perform optimally.
