eSUN PLA Filament

[LeoDude 0]

Dear Ultimakers,

 

I started using eSUN PLA Black filament, the recommended temperature on the filament saying 190-220C, I begun with 200C & print would not stick to the raft (after few layers above the raft the print would warp & detached from the raft), I  increased printing temperature by 5C each test till reaching temperature 235C when everything turn OK with no faulty print & no show of over heating on the print itself. Is there something wrong as I went 15C above recommended temperature? (P.S. I always print PLA with no heated bed just blue tape & glue). I checked filament again if it is PLA+ but it says just PLA.

 

I used before Ultimaker Metallic Silver PLA, PrimaValue black & white PLA Filament, Polymaker White filament all within 210 & below without a problem. And just before changing to eSUN I was printing with PrimaValue Black PLA Filament at 195C. Same model without a problem.

 

Thank you in advance for your input.

No, you did nothing wrong. Each filament will have a different temperature range that's necessary for good prints. If you have an Ultimaker 2/2+ you may have reduced lifetime on the hot-end coupler at higher temps however.

 

For the best experience, I'd recommend going back to the original Ultimaker PLA (yes it can be pricey, but it really works well).

Thanks for the reply to my question.

 

I do not think its a matter of hot end being of low efficacy, as the printer fairly new, not to mention I just changed to PrimaValue Grey filament & printing on 195C without a problem. And the print is rock sold.

 

If it was the case with all filament, then would say the hot end not doing a great job like the new one. But its is a solo event with eSUN filament.

 

Is it normal for some filament that you need higher temperature than their recommended range? without thinking its a hot end fault as its always printing within the range with Ultimaker, PrimaValue & polymaker filaments, or still it might be a hot end problem?

It is certainly true that different PLA filaments will have different characteristics and may need different temperatures to produce a decent print with the same settings; not the norm but it happens. I am talking about "normal" PLA nor the PLAs mixed with wood, bronze etc. I have personally never gone above 220 and these days I rarely go beyond 200. So I think the answer to your last question is NO.

 

Now  if people have a blockage in the feed system then not knowing or understanding that they may go to ridiculous temps to get the filament extruded - 235 is a good example. If you printed the PrimaValue Grey after the eSun then I think you can say that your printer is fine. I am not familiar with eSun, maybe it is not very good or you just received a bad reel of filament. That does happen, I had to return a reel of Colorfabb filament once and they are considered to be one of the top suppliers. (to their credit I had a new reel from Holland within 2-3 days no problems). 

 

Personally I would junk the eSun reel and move on.

Actually, I have to print black eSun PLA+ at 230-235C in order to get good results. I haven't checked the accuracy of my nozzle temperature yet so there might be an issue there that I'm not aware of.

I am getting stringing at nozzle temp 215 degrees with eSun PLA+ silver filament. The packaging recommended a sweet spot of 210-215 degrees. I'm going to try 208 on my next print.

 

Other than a few rogue strings hanging off the print, they filament looks fantastic.

Those strings on the side don't have a lot to do with the filament.

 

Those happen on filament changes when changing from PVA back to PLA.  The old nozzle is leaking a bit and there is this little string/noodle sticking out of the nozzle and when it starts printing again it gets attached to the side of the print.

 

One solution is a prime tower.  There is an option in cura to add a prime tower.  Make sure the prime tower isn't in a rear corner - it does better in the rear center if possible.
