'A Good and Superb PLA!'Frankly Id heard many fine things and some favorable comment on SUNLU Filaments!So having bought a roll an done a project I can Honestly Report that most of the favorable things reported are in truth correct as it is a 'Very Fine' Plastic and SUNLU definitely has its act together!.PROS:Makes a Neat an Classy looking Part!Easy to Run, Easy to Set Up!Its the Real Deal You Get A Full Roll of !st Class Filament!Almost the Only Silk PLA Plus+ on the Market!A Real Bargain as the Price is Fantastic for what you get!.Fast ebay Shipping cannot be Beat!CONS:None actually cept If Id known this was a PLA+ Id have ordered it sooner!In General:Now In My Useage The SUNLU worked and printed quite well.Setup was simple, I use Sticky Blue painters tape.Set Nozzle at 259 and Bed 109 and let warmup for 10-15 mins.I set 1st Layer at Nozzle 257 Bed 100, Speed at 35 or 40!Then after 1st layer is down and hard I set the rest of the run at about say:Nozzle 250- or 255 Bed 60 0r 75 and let Speed run at 45.True "I Know" at those settings Ill get some stringing but 'I dont have any problems with layers not bonding and It don't take 'All Day' to get the part finished either.Yes I know there are all kinds of 'Micro-settings, But I know that most machines have there own 'Pet Settings for wanting to run right.Now most folks want to run 'Cold and Fast' But I tried that and got a LOT of junk parts!.For me I found that "Slow but Hot" seems to get 'Better Parts'.Me I adjust my speed with a New Plastic until Stringing starts to appear then I back off fast!.I also run my tests a 'Bit Differently' as many will run a ducky or a benchly and its a good way.For Myself I have a small but 'difficult part', See it dont take much Plastic but if the plastic is good enoughto make a 'Difficult Part' then the easy stuff will run Home Free as the SUNLU did!Now One Major Complaint w Sunlu is it doesnt extrude well or the teeth dont grip the Plastic right!.Yes at one time 'I Had' that issue but here is how I worked around it!.A HOT TIP:Now sooner or later when the teeth wear down you will have to replace that drive extruder gear!.On most new machines its the round Brass One w the two small allen nuts sticking out the top side!Most guys re install the gear wrong, I know I did?Yes I did as most of us will do what the YouTube guys did as they 'Set It' Plumb in the middle!.Hey if you are satisfied and it works for you go for it!But there's a Better Way, In stead of in the Middle I just slid the Gear down a notch and let the plasticrun off the teeth on the Top Side of the Gear as it grips better and runs smoother too.Oh yes it will surely wear like they all do in time, But if you did it right there is no great need to replace the gear not by any means sic!.Just loosen the allens then "CAREFULLY" slide the gear back upwards until the Teeth on the bottom which are still good are NOW gripping the plastic as I think its pretty neat to reuse and get good service from the same part twice!.TO: Close;SUNLU Silk PLA is super good stuff that is easy to set up, It runs fine and makes a good part!.And to Finish Its the only PLA+ that runs a silk fibre so it has Very Considerable strength and I definitelyIntend to try some Printer Gears with this and the smooth finish makes a classy looking part too!.Kudos to the Seller!Kudos to ebay!Nuff Said.IndianaED
