材料耐得住,但是不建議,溫度幾度呢?

90度

那建議使用鑽石料,原料也是食品級的,不過製造經過很多過程,也是都會汙染的,所以請自行判斷

有買過可以過一百的耐高溫PLA XD
嗯嗯..所以鑽石料印完大概可以到多少度？

應該可以撐到100度

李sir可以當先鋒試試

也可以這樣

100度應該只是熱變形溫度吧?到目前為止,沒有任何證據顯示長時間在高溫下使用任何塑料製品不會釋出析出物,請不要真拿來裝熱水飲用,而一般醫療塑膠器械進行超高速老化驗證大多也只做到75度左右而已.

所以我說自行判斷~~Thanks

應該已售完吧？

嗯嗯 感謝

要燒韌體進去?

如果不是排線問題，就是螢幕太亮，背後有旋鈕可調亮度

我的有時也會 把出料口沾黏的料清清又好了 我是用口紅膠的 有亮粉的料感覺比較黏 不知道是不是因為這樣容易黏在出料口

微調間隙、放慢速度

另有一番風味!

很厲害了。

檔案是那下載呢？

試色

Something to add: He prints fine so far but on retracts The extruder makes Noise on pushing filament back in movements...

I use acetone, bought from the hardware store coz it is stronger than the one for nail polish remover. I dilute the nozzle to melt out all any residue from filaments for 12hrs. Because I don't have guitar strings, I use a needle to clean the hole too, then back to acetone bath.

But i thought acetone only works for ABS? PLA seemed pretty resistant to acetone...

You can get 0.4mm drill bits. they are tiny - but they do work. To avoid breaking them I always preheat hot end to 200 degrees first.

Yes your correct on abs. But on PLA with concentrated acetone, and leaving it for at least 12hrs or so will start to break down any plastic inside the nozzle. It will clean the side wall of the nozzle and then you can use needle to push out any stuff easily onto the hole.

Ohh thats good to know!!! Just ordered some THF which dissolves PLA :DJust one More Thing for either Acetone or THF: Do I have to disassemble The thermistor from The hotend for This act? :/

It would be great to seperate them. I only dilute the metal parts.

I was hoping that you wouldn't say that :D So I'll have to cut open the shrinking tube, desolder the thermistor, pull it out, clean the nozzle (hope the teflone tube doesn't react on acetone / THF) and then put the thermistor back in, put shrinking tub e on, solder the thermistor again and shrink the tube on it. Right?

Another question: The teflon tube in the hotend nozzle part - is it replaceable? In my case it's stuck in there pretty hard. Not that I need to replace it right now, but I was wondering :)

The Teflon tube, yes I believe so. When I ordered my Atom, I made sure that I also ordered 2 more nozzle with out the tube.
And if your gonna cut the wire, might as well use a connector so it will be easily to remove the resistor again for future cleaning.

By heating the nozzle, it should easily remove tube after.

Yeah... Should have ordered some nozzles too :/ What kind of connector do you use for the thermistor wire?

Solder first the tip

And you may use one of these, but I use the pin. Male and female.
