eSUN PLA Filament

Recommended Posts

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.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
