failed 3d prints, and how to fix them

by:Top-In     2020-08-03
3D printers are really cool, but so far they are new technology and very unreliable.
I have a year of experience in 3D printing and I tried to print various models on my printer again and again but failed.
However, after many failures, I learned one or two things for the first time about the setup and tips for correct 3D printing.
If you have any questions, please ask them in the comments and vote for me if that helps!
This is probably one of the most common ways for any 3D printing to fail.
The 3D printer works by building objects layer by layer, and if these layers fall off the bed, you usually get plastic spaghetti instead of a clean printed part.
There are three things that contribute to the adhesion of the bed: I found the best adhesion of ABS by 80-
90 ° bed, PET tape, film with Elmer glue stick on top.
I found that the best adhesion of PLA is 0-
50 ° bed, PET tape or glue for uncovered glass and Elmer.
Suggestions and methods from reviews include: Use the Hairspray from the dollar store on hot glass to get a rock stick with PLA.
I in 220 degree of bed print 110 degrees Celsius of ABS.
Another common failure is over-extrusion.
Excessive extrusion occurs when your 3D printer rolls out too much plastic too fast, causing the end of the nozzle to clog.
This blockage is growing more and more until hotend completely stops squeezing, leaving your print unfinished.
The best way to prevent over-extrusion is: On the other side of the over-extrusion, extrusion occurs when the plastic flows out of the container.
The layers are not hot enough and too sticky, and the printing is easy to fall off.
The best way to stop extrusion is to check if there is a blockage in the nozzle and increase the hot end temperature.
I would suggest adding it in five degrees increments until you get a part with good strength and good nozzle flow.
One of the most frustrating failures is when your filament loops under itself, tightening until it is completely unsqueezed.
The only way to solve this problem is: when you change the filament, be sure to hold the loose end firmly and put the spool back in the box so that the end does not slide into itself.
On any 3D printing, the bed must be perfectly flat, otherwise various problems will occur during the printing process, such as: leveling your building board is relatively simple.
Watch this wonderful video on how to do this, or use the guide below.
Note: This video is not mine and I don\'t believe it.
To level the building board of a 3D printer (AKA print bed)
You need: Take a Letter paper in the first step, the weight is normal, and fold it in half.
Put it under the nozzle of the 3D printer and then put the hat on the paper.
The paper should be sandwiched between the bed and the nozzle.
Now, try to slide out under the nozzle.
If the paper moves freely, the nozzle is too high on the print bed.
If the resistance is too large (
You have to pull hard on the paper to release it)
The nozzle is too close to the print bed.
Step 2 use the findings in step 1 and take an Allen key that meets the printers bed clip: Step 3 Repeat steps 1 and 2 for all four corners of the build board.
3D printing had a great time.
It can be frustrating at times, but every time you fail, figure out what\'s going on and prevent this from happening again!
