How
to build a great first layer
The first layer for 3d printing is very
important. With bad first layer, the whole printing will fail.
Here are some tips may help us make better
first layer.
1. Build plate leveling
Keep a good distance between nozzles and build plate. Too
close, the nozzle will scratch the plate; too far, the first layer won’t stick
to plate. We could put an A4 paper on build plate, and then move the nozzle on
it. Pull the paper out without damage the paper and strength.
Test: print a model first to check if first layer is ok and
if the print could be finished well.
2. Set 5 ℃ higher for
the first layer
Higher temperature will fully melt the filament and make it
stickier. This helps the first layer stick to build plate well. Based on our
experience, 5 ℃ would be good.
3. Slow down the print speed
Slow printing speed will reduce the strings when nozzles
extrude filament. We suggest 30%-50% of the normal speed.
4. Thickness of first layer
First layer need more heat and filament to stick tight. Its
thickness should be half of the nozzle diameter. For 0.4mm nozzle, 0.2mm layer
thickness is needed.
5. Build plate sticker
Good sticker could help the first layer stick to plate
tight.
For PLA filament, PET, polyimide tape and masking tape
paper are all good choices.
For ABS filament, PET and polyimide tape.
Someone used hair gel, Acetone melted ABS. They work too.
And solid glue is a good choice too.
6. No cooling for the first layer
Shut down the fan when printing the first layer.
Please tell us if you have more ideas! That's
all for today! See you!
