【3D Printing Application】Print Quality Comparison: What are the Differences in Precision?


We've previously introduced how the types of 3D printing support filaments affect print results (Further reading: Support Effect Comparison: Which Method Suits You?). But what differences would there be if we used an Ultimaker industrial-grade 3D printer versus a hobbyist-grade Prusa I3 MK3S 3D printer for printing? Today, we'll demonstrate using internal drill components!
 


(Contestant No. 1: Original Prusa i3 MK3S 3D Printer, Contestant No. 2: Ultimaker 3D Printer)


This time, we mainly used the Original Prusa i3 MK3S single-nozzle 3D printer and the Ultimaker dual-nozzle 3D printer, printing the part body and support structures in different ways. At first glance, there seemed to be no difference.



Contestant No. 1 used the Prusa i3 MK3S 3D printer. Unlike the Ultimaker 3D printer, which uses a Bowden tube system to feed filament, the Prusa i3 MK3S 3D printer uses direct drive (What is direct drive?). The nozzle itself has an extruder, so the filament is directly pushed into the heated nozzle, making material changes relatively simple. However, because the nozzle and the drive motor are integrated, the nozzle bears the weight and vibration of the extruder during printing.



The support structure density of the 3D printer is lower than that of the main body, and the structure is looser. When disassembling, it can easily separate from the main body of the part, while ensuring the accuracy and texture of the finished product.


(The low-density structural纹路 (patterns) are clearly visible before the supports are removed.)
 
3D printing is a huge project where an unexpected interruption is the biggest fear. The Prusa i3 MK3S 3D printer also has a reliable power loss recovery feature. The 3D printer automatically detects power interruptions and shuts down the heated nozzle, and can resume printing after power is restored.


The Ultimaker dual-nozzle 3D printer, on the other hand, can use two types of filament simultaneously. Our second contestant used water-soluble PVA filament for the support structure, printing the main part and the supports concurrently. After completion, simply immerse the entire assembly in cold water for easy dissolution, resulting in a very smooth surface for the part.

 

 

The drill part has a spiral structure with a diameter of 2.5 cm and many connection holes. Both the Prusa i3 MK3S 3D printer and the Ultimaker printer produced highly accurate results for these parts, but there were slight differences in the details.

The industrial-grade Ultimaker 3D printer features dual nozzles, allowing for the simultaneous printing of two filament types or colors, resulting in higher surface precision for the finished product and opening up more possibilities for 3D printing. Although the professional-grade Prusa i3 MK3S 3D printer may be slightly less precise than the Ultimaker 3D printer, it still performs exceptionally well for a machine under fifty thousand!

To ensure fairness, both 3D printers used eSUN's PLA filament. There is no good or bad 3D printer; choosing one that meets your needs will achieve the highest efficiency in production!
