Was looking at HTPLA but after reading how finicky it was I decided not to give it a try. In the process I ran across FilaCube PLA-2 after reading some reviews and the specs I decided to give it a try.
Back when I first bought my 3D printer I printed a bottle opener for opening water and soda bottles. She wore out/broke that one. So this would be a good time to try some new filament. The spool says it prints between 190c-230c so what I normally so is split the difference. It also says to set the bed temperature between none-40c. They claim the bed doesn’t need to be heated. The 1st attempt after a few layers the part came loose so that was no go. 2nd try I sprayed some Aquanet hair spray on the glass plate that sit on the bed. Same results it came loose again. 3rd attempt I set the bed temperature to 35c, also realized that I had the extruder temperature set to 200c so I increased it to 210c. This time it stuck to the bed and the print completed.
The finish was pretty smooth, much better than I was getting with the Inland PLA+ I had been using. It appears to be a little more flexible than PLA+ and the claim is that it’s stronger, time will tell if that is true. It even looked good when it was printed at 0.30 layer height, the others were printed at o.20. Those are the only 2 layer heights I’ve tried. The color I bought was silver, I will be buying some more when the time comes.
