Just received my first bulk order of filament. I ordered 10 rolls of RFID PLA and I gotta say, the packaging was horrible. All 10 boxes were just stacked in a very large plastic wrapper and taped tightly shut. Nothing was protecting the product so by the time it arrive at my home 4 days later, every single box inside had damage (partially crushed), mostly on the corners. Really guys, how expensive is a cardboard box…and why did you ship 10 rolls of filament in a flimsy plastic bag. Just charge me $4.50 for the damn box. I ordered 10 rolls of another brand from Amazon, and it was all packed in BOX and very protected. Not a single box inside had any damage. I love my K2, but thinking that for the delay and risk of damage, it’s not worth the extra $2/roll for your RFID PLA filament.
I am not ordering usually so many rolls at once because I need 1-2 rolls new filament max for any project and I usually buy them @ the river with free next day shipping.
After my Hyper-PLA rolls which came with the printer finished (except the blue one which is a color which I need to use very seldom) after using it mainly for fast prototyping (most of the finished parts require other filaments like PETG, Silk or matte PLA, multicolor or even ASA but very seldom just single color normal PLA(+).
I looked up what I could test as highspeed filament other than the Hyper PLA and also the eSun PLA+HS which I use a lot of times for some special purpose (the normal white version has a good transmission distance for Hueforge and litophane prints) and it cost me usually ~20€/kg with free next day shipment even for one roll.
I found Elegoo Rapid PLA+ (I own also Elegoo SLA printers and use some Elegoo resin) where I ordered a pack of black and white filament (2x1 kg) for €29.90 incl 20% tax on the river with free delivery next day. For the Creality Hyper PLA (with RFID) I should pay 29.90 for ONE roll and get free shipping for orders or at least 3 of them with delivery after 3-5 days!
So I tested the Elegoo one and I am very happy with it. I can print even @ 25 mm³/s (Creality Hyper PLA has 23 mm³/s) and the only drawback is that I use my own filament profile!
As long as they work I put self made RFID tags on the rolls, just to have the right color and type visible, you still need to select the filament profile in slicer manually because I calibrate them with Calibration of new (non CR preconfigured) filament - how to for K2 tu use right PA/flow rate/cooling settings and NEVER use Generic xxxx!
