Batch colours don’t match
Got a box of 10xGold Silk+ PLA. Made sure I had flows and speed perfect, dried 3 spools at 50c for 12 hours before starting a big customer job. After 1kg spool was used up AT 30mm/s I put a new spool in and the colour changed a LOT. You just can’t rely on Sunlu batch numbers for colours which is sad because the first reel was a gorgeous colour. If you want reliable colouring across batch numbers it’s best to go with Bambu. I had to start the project again (2.5 days into a print) and am now stuck with 8 spools of unreliable colouring. I wish I could upload a photo to show just how much the colour changed.
