Bed Slinger 3D Printer - All You Need to Know


3D printing enables us to transform any digital design into a tangible model with high accuracy. This technology is always evolving to amaze us with everything new. With the development of this technology, different types and techniques appeared. Among these technologies is FDM technology.


Fused Deposition Modeling (FDM) technology stands as one of the most widely used 3D printing methods due to its cost-effectiveness and versatility. It works by extruding thermoplastic filaments, such as ABS, PLA, or PETG, through a heated nozzle, laying the material down layer by layer to build up the final object. This method is particularly popular among hobbyists, educators, and professionals because it's accessible and easy to use.


FDM printers themselves also operate with different machine mechanisms and technologies such as Cartesian and core XY printers.


Cartesian 3D printers rely on the X, Y, and Z axes to move the print head and bed. These printers are widely used due to their simplicity, reliability, and user-friendly design. Additionally, they tend to be more budget-friendly compared to CoreXY printers. 


Cartesian printers, in turn, are divided into two types: cantilever and bed slinger.


In a bed slinger mechanism, the print bed moves in the Y direction, while the print head moves in the X and Z directions which always have dual guides. This mechanism is known for its simplicity and ease of use, making it the most popular choice.

On the other hand, in the cantilever mechanism, the print bed typically moves in Y axis, and the extruder moves along X and Z axes. This design often sees the extruder mounted on a single arm or a beam that extends out, with no support on the opposite end, resembling a cantilever.

While the core XY use a belt-driven system to move the print head in the X and Y directions. And the print bed moves only in the Z direction. This system allows for faster and more accurate printing, making CoreXY printers ideal for printing complex geometries. However, they are more expensive and difficult to set up than Cartesian printers.

In this article we will focus specifically on the bed slinger type of Cartesian printers, discussing their unique features, benefits, cons and applications. Understanding what sets bed slinger printers apart will help you determine if this style of printer is the right choice for your 3D printing needs.


Lets get started!


What is a Bed slinger 3D Printer?

A bed slinger 3D printer uses a specific type of motion system called a Cartesian motion system. This system relies on three axes: X, Y, and Z. Each axis is controlled by its own motor. Here's a breakdown of how it works:bed-slinger-3d-printer

X-axis: The printhead moves back and forth across this axis.

Y-axis: The print bed moves front and back along this axis, often referred to as "slinging" the bed, hence the name.

Z-axis: The gantry, which holds the printhead assembly, moves up and down on this axis and always have dual guides.

This creates a three-dimensional space where the printer can deposit molten filament layer by layer to build your 3D object.


Now that we understand what a bed slinger 3D printer is and how it works, let’s understand its benefits, pros, and cons.
