Bambu PLA Jade White
1251g - Start weight with spool.
1250g - After 1 hour.
1250g - After 3 hours.
1250g - After 6 hours.
1250g - After 7 hours, 22%RH in dryer.
1249g - After 8 hours, 22%RH in dryer.
Result 0.16% loss weight. It’s hard for me to assess this since the filament with spool has already been dried before.
And else. I think the dryer indicate of humidity is a middle of humidity in room and real humidity in dryer, because now my humidity in room is 56%RH and in dryer 23%RH. Both value dropped down. And real humidity of in dryer possible about 10%RH - 15%RH for now but I have no hardware to check it.
I use Adafruit BME 280 sensors and they work great but you have to get a mictocontroller to connect them to. You can find BME 280’s cheaper than Adafruit but they have good support if one runs into a problem
For what it is worth, I had 2 BL refills of PLA which I put on BL spools I already had.
Weighed both spools before putting filament on.
Each spool weighed 212g
I need to weigh a few of the cardboard cores to get a working idea of what is the average weight of core.
My filled spools weighed 1247g (white) and 1249g (black). Back out 212g for spool and you end up with 1035g and 1037b. If I had the core I could back it out too. I expect the cores come out around 35 - 40g is my guess.
For me, if I get a refill that I back out the core weight it comes in at around 1000g, it should be dry.
Thank you. Unfortunately I’m not an engineer, but I’ve been interested in this part of science since childhood. Maybe in the future I’ll build my own device.
Now I use these hygrometers, although I buy them in my region marketplace and the specifications stated that the minimum percentage of relative humidity was 10%, but in reality it was 20%.
One doesn’t really need to do all that. More just an FYI that there is technology out there to monitor one printer pretty accurately.
I even put a VOC/particulate sensor in my P1C but I already had the sensors.
Here is the result of fans in my silica bead containers.
This picture is of the desiccant after about 1 month in an AMS compared to the silica beads when they go in the container. This all went in my oven at 250°F and after about 2 hours it was all a very dark blue and back in Dry & Dry jug.
The 3mf uploaded in the first post has variable layer height enabled. So I do not wonder about the result. I disabled variable layer height and set the out wall speed down to 150 and got a clean result on my P1S. I do not dry my PLA filament and use mostly PLA Basic and Sunlu PLA Plus 2.0 if I need a quick restock. And I do not believe this causes anything like shown on your pictures. If it would cause blobs or bad layer adhesion.
In BambuStudio in the Preview jsut switch to Layer Height and you will see the lines as you have it in your prints. So basically bad setting for this model.
