so i finally made my own 3d printer without using heatbed now while printing my pla sticks and curl to nozzle,,it goes up to nozzle and not to bed(glass bed)??is heatbed necessary for diy 3d printer???

for small PLA (so 40x40 mm) things, no. Bluetape and other surfaces are fine.

most larger things and non PLA yes

ok i am using PLA and wanted to print object within 10cm range so do i have to buy heatbed or using just gluestick is fine???

100mm on Blue Tape would be ok.... once it's setup right.

Gluestik on glass will work, its what I use.

You have to get the plate level, and use the 1 piece of paper thickness to set the nozzle height.
It will be unforgiving to nozzle height. Too far away and it will curl. Too close and plastic wont come out.

You will be limited to PLA. I have managed to get a TPU to stick but it was only 1 time and a very small part test.

ABS and PETG not going to work.

Good luck.

RigidInk PLA+ printed on blue tape sticks brilliantly. I've printed 400mm long parts using this combination.

thanks all for quick reply

now i am using a small 25INR(0.36USD)(see attachments) glue stick for glass is it fine??

and i have one problem when i click on print button then my hotend starts heating to 185C temperature and pla comes out of nozzle before the actual printing starts and this pla sticks to nozzle and follow the nozzle,,this will ruins the whole printing......

so how to stops the pla coming out before printing starts???

Maybe can be fixed in software.

The firmware may have a preset priming value, but the slicer may feed some too.
Check the slicer first.

Check the "start gcode" section of your machines settings (at least in cura).
Lookup G92 and G1 codes.

i am begineer so i dont know how to check software(slic3r 1.1.7) and how to stop pre pla coming out of nozzle do u know where is the option for that??

I have a pair of tweezers or scissors handy, I do all my warming up 10mm above bed, and when it hits temp or around 185c I start purging 10-20mm on extruder and remove, then hit print...and if any more come out remove as it's moving to zero
