Hi all
Have finally received new Makerbot and box of PLA and ABS filament here in Thailand. I am a complete newbie but the kids I teach will help on the mutual learning curve I am sure. My CONCERN IS ABOUT HUMIDITY and how quickly I might screw up plastic once I open the vacuum sealed dessicant laden plastic bags.
Will be a fight to get my classroom AC on 24-7 so any advice on 3D printing in tropical countries would be much appreciated.
Simply get a plastic sealable container or bag and put a desiccant pack in it for long term storage. You can also put in an oven for 20 min at 170f to dry out
ABS will be the bigger problem. Keep it stored when not in use.
PLA tends to be more hydrophobic than hydrophilic - it depends more on the additives (colours and other non-PLA components) than the primary PLA ingredient. As it relates to odour, PLA is definitely more pleasant to use in a kid-friendly environment. I always print with PLA unless the application demands ABS (e.g. a more heat-tolerant extruder upgrade).
