FDM
The most common 3d printing method
FDM (Fused Deposition Modeling) >
A 3D printing method in which a thermoplastic filament is melted and extruded through a nozzle to print an object layer by layer. This is the most common type of 3D printer because of its affordability, ease of use, and versatility.
There are two types of FDM Printer: Bedslinger and Core XY.
What is a Bedslinger Printer?
In a bedslinger printer, the print head moves along the X-axis and sometimes the Z-axis, while the print bed moves back and forth along the Y-axis. This relatively simple system has contributed to its popularity, especially among hobbyists and beginners.
What is a Core XY Printer?
The CoreXY mechanism is a type of 3D printer design known for its lightweight and fast-moving print head. The defining characteristic of CoreXY is that the belts crisscross, allowing the print head to move independently of the print bed, which remains stationary during the printing process.
Bed Slinger
Core XY
Price
Generally cheaper due to lower material cost and simpler design.
Generally, more expensive due to the complexity and cost of high-quality materials.
Maintaince
The design is simpler, making them easier to build, maintain, and repair.
The assembly and maintenance are complex, requiring regular upkeep.
Print speed
Slower due to the movement of the entire bed.
Faster due to the stationary motors and lighter moving parts.
Quality
The moving bed causes more vibration, which creates lower-quality prints.
It minimizes vibration-induced errors, leading to highly accurate prints
Size of bed
As the size of the print bed increases, the issues with speed and vibration become worse.
The movement along the X- and Y-axes allows for larger prints.
