[6 Fixes] 3D Printer Printing Too Thin
It can be pretty irritating when you’re up to crafting an essential 3D item for your project and suddenly it starts printing thin layers. Well, it’s a common scenario as many users have already complained about facing this issue.
This issue is particularly named Under Extrusion. It can be caused by several factors including a blocked nozzle, stuck filament spools, etc. No matter what the cause is to blame for your problem, some fruitful solutions to fix it include cleaning the residual material blocking the nozzle, unwinding and rewinding the spools, etc.
As you’ve got the basic idea, let’s dive deeper to know all the possible causes and permanent solutions for this thin printing issue.
Why the 3D Printer Is Printing Too Thin?
As you know, thin layers are produced when the 3D printer fails to supply the necessary material through the nozzle. But why did this occurrence happen? Well, these are the causes that lead you to this problem –
1. Blocked Nozzle
When you don’t clean the nozzle over time, the leftover material accumulates and eventually blocks the outgoing passage. Therefore, when the printer is up to providing the material, it faces the obstacle and as a result, thin layers appear.
To check if the problem is caused by a blocked nozzle or not, you can try pushing the filament material yourself. If it passes through almost without resistance then the nozzle is okay. Else, the nozzle is making this mess.
2. Congested Extruder
Sometimes the extruder also gets stuck by the clogged filament, which hinders the new thread material from passing through the nozzle, and the issue occurs.
3. Inaccurate Extruder Steps
Basically, from the beginning, the extruder steps are concluded in the firmware of the printer. So, if you’ve modified them, perhaps you’ve messed up with the steps and therefore, you’re facing the problem.
4. Stuck Filament Spools
If the spool isn’t properly winding, the printer won’t rattle down the threads accurately and the filaments will get stuck. That’s why friction gets created and the motor loses its grip on the material while delivering it into the 3D printer. So, the material flow becomes low and causes thin layers.
5. Filament Feeder Gets Low Pressure
Only a few 3D printers offer to adjust the filament feeder’s pressure settings. It controls the pressure on the filament and allows the motor to get a good grip on the material. If the pressure gets low, the motor loses its grip and the problem arises.
To ensure that it’s the cause, check the filament pressure with your hand. To do so, hold down the filament when the motor rotates while printing. If you feel the filament is slipping, that means the pressure is low.
6. Higher Printing Speed
When the printing speed doesn’t match the flow rate and exceeds, sufficient material will fail to supply through the nozzle. Therefore, the layers become inaccurate or thin.
7. Lower Printing Temperature
If your printing temperature isn’t accurate, the nozzle won’t be necessarily hot enough to melt the filament as expected so that the material can go through the nozzle spontaneously. Ultimately, this causes the problem.
How to Prevent the 3D Printer From Printing Too Thin?
Now that you’ve known the causes in detail, you can detect the cause that is to blame for your situation and apply the solutions accordingly. Here are the solutions –
Solution 1: Clean Off Congested Material
If your printer’s nozzle and extruder are jammed and causing the issue, you just need to clean the unused leftover material from them.
Solution 2: Calibrate the Extruder Steps
Even though the calibration procedure isn’t too hard to perform, if you’re trying this for the first time, the process may seem confusing to you. But wait, there’s still nothing to worry about as you can get the whole procedure step by step from here. Just follow the instructions accordingly.
Solution 3: Use Proper Filament Diameter
To ensure an appropriate rate of filament supply, you should use the proper filament diameter input. Make use of calipers to measure the correct diameter.
Solution 4: Check the Pressure
You’ve to check the pressure settings to make sure the perfect pressure is on the filament feeder. confirm that the feeder’s tensile settings are perfectly set so that the filament-pushing process to the extruder remains perfect.
Solution 5: Adjust Printing Speed and Temperature
It’s clear by now that keeping the printing speed and temperature accurate is so important to recover from this problem. If your problem is related to them, you must ensure two things. One, maintain the speed at a suitable slow rate, and two, keep the perfect temperature according to the filament. You can make use of a temperature tower in this case.
Solution 6: Check the Supply Tube
Most 3D printers use Teflon tubes to ensure a constant feed rate across the nozzle, as they offer an even and relentless path for the material. So, check the condition of the tube and make sure they’re not twisted or broken. Otherwise, you need to replace them.
That’s all the relevant solutions for keeping your 3D printer apart from printing thin layers.
Frequently Asked Questions (FAQs)
How thin is too thin for 3D printing?
Most 3D printers come with a set of nozzles that are 0.3 to 0.5mm in diameter in terms of printing thin-wall. That means this is the minimum thickness for 3D printing. But if the nozzles somehow fail to generate this thickness or the diameter is less than 0.4mm, it’ll be considered too thin.
How can I make my 3D print robust?
In order to make your 3D prints thicker and more robust, you can do this in several ways. But the effective ones are to use a nozzle with a greater diameter, use a complex infill pattern, and increase wall thickness and infill density.
Are thicker layers stronger the 3D printing?
The fact is using a greater diameter can surely increase the impact and tensile strength of your 3D printing. In addition, if you increase the shell thickness of the printed parts, you’ll notably enhance the rigidity of the whole 3D structure regardless of the lower infill percentage.
