It's been a few weeks since I used up the Hyper PLA that came with the K1. I had bought so many other PLA filaments for testing that I hadn't been buying any new ones, but I think I adjusted the basic slicer settings, so I decided to buy the official Hyper PLA for high-speed printing.

Hyper PLA is a product released by Creality alongside the K1 launch as a high-speed printing PLA. As mentioned in the description, it is said to have features such as better supply and effective cooling.

Due to its high-speed printing characteristics, it seems to be a PLA that supplies quickly at high temperatures and has good cooling, which are necessary properties.

It appears to be officially imported and sold by DY Air in Korea, and I also purchased it through the DY Air site.

有趣的是，官网售价为每公斤24美元，而在DY Air上每公斤售价为19,900韩元……考虑到汇率，韩国要便宜得多。。

What is this.. is it a price error.. should I buy a huge amount..

It is sold in 5 colors: white, black, gray, red, and blue, but I really wanted to use the black one, but it's currently out of stock, so ㅠㅠ I bought the other 4 colors excluding black.

And since I received it today, I opened the red one right away and tried printing it.
I printed using Draft Fast (0.25 mm), one of the high-speed settings I shared in the last post. However, since the filament is PLA, I set the temperature to the default 220 degrees.

Creality K1 Basic Slicer Settings with eSun PLA+
The Creality K1, a high-speed 3D printer, is truly fast and a great machine, but the options provided by the default slicer are too sparse. Therefore, I will share the settings used with the widely used eSUN PLA+ filament, utilizing data from my own tests.

At first, I didn't get good benchmark data, but after struggling with it several times, I guess my skills have improved. It printed beautifully all at once.

The red material has a slight glossy feel, so some uneven texture is visible in the middle, but considering the high-speed print (18 minutes), this seems to pass the standard.

It seems important to open the top lid when printing PLA to let the internal temperature out. (I should test this.)

However, when viewed from the front, slight warping at the top is noticeable. It seems there might be an issue with cooling?

Compared with the eSUN PLA+ print results from the previous test. Overall, they look about the same.

It seems like eSUN filament might actually be better...

Since eSUN PLA+ produces sufficient results just by raising the print temperature by 5~10 degrees, is it really necessary to buy Hyper PLA... It makes me hesitate for a moment.

Well... I thought it might be better, so I decided to test it a bit more.
