There are several ways to tell if a 3D printing nozzle is too close to the printer’s bed. These include material not coming out of the nozzle and the nozzle becoming blocked by printing material. The nozzle should typically be .06mm to .2mm from the bed.
This post will show you how to tell if a 3D printing nozzle is too close to the bed of your printer. I’ll provide you with some common issues with the printer caused by the nozzle being too close and give you the general measurement for the distance from the nozzle to the bed.
Let’s get after it.

Key Takeaways
- If you are experiencing issues with how your 3D printer is operating, it can be caused by the printing nozzle being too close to the bed.
- The nozzle should generally be about .06mm to .2mm from the bed for optimal performance and to avoid any issues. If you don’t have a caliper to measure this, you can use a piece of paper.
- Symptoms of a nozzle being too close to the bed include printing material not coming out of the nozzle and the nozzle becoming blocked by printing material.
How to Tell if 3D Printing Nozzle is Too Close to Bed
If you are running into any issues while using a 3D printer, it could be caused by the printing nozzle being too close to the bed. This is a common occurrence and is easy to adjust and fix when you understand the issue.
One sign that your nozzle is too close to your bed is that no printing material comes out of the nozzle. When it gets too close to the bed, this can impede the proper flow of the printed material, and the printer won’t work properly.
If you see melted plastic or other printed material gunked up over the nozzle, that’s another sign that the printing nozzle is too close to the bed. When the nozzle is too close, it can cause this build-up to happen, impacting how the printer functions.
Another sign of the nozzle being too close is that the printer won’t print the first few layers of a project. If you think your nozzle is too close, attempt a practice print and watch the nozzle. If it starts on a later layer, the nozzle is too close to the bed.
A simple test you can do to ensure that your nozzle is adjusted correctly is to try and slide a regular piece of paper between the nozzle and the bed. If the paper slips through without getting stuck, you have things adjusted properly.
If the paper gets stuck as you pass it between the nozzle and the bed, you’ll need to make adjustments. Most 3D printers should have a distance of .06mm to .2mm between the bed and the nozzle.
A regular piece of paper is about .1mm, which is why sliding a piece through the bed and nozzle helps you assess proper adjustments.
What Happens if Nozzle is Too Close to Bed?
All the symptoms I mentioned above can happen if your 3D printing nozzle is too close to the printing bed. If you try to operate your printer with this issue, you can cause some damage that can be difficult to deal with.
If your printer is not operating correctly and has a build-up of plastic or other printed material on the nozzle, it’s probably too close to the bed. And if no material comes out of the nozzle at all, that’s another sign things are too close.
3D Printer Nozzle Height Calibration
Adjusting the height for your 3D printer is typically really easy, and the user manual or other paperwork you get with the printer should instruct you on how to calibrate things. You can usually just make a minor adjustment, and things will operate normally again.
Every printer model is different, so there isn’t one single way to calibrate the printing nozzle. You should have a distance of .06mm to .2mm, but how to make those adjustments can vary from model to model.
FAQs
Here are a few quick answers to the most commonly asked questions relating to if a 3D printing nozzle is too close to the bed.
How close should 3D printer nozzle be from bed?
The printing nozzle of your 3D printer should be about .06mm to .2mm from the bed. You can measure this using a caliper. If you don’t have one, you can use a piece of paper, which should slide through without getting stuck.
How do I know if my print bed is too high or too low?
By looking at how the printer prints, you can check to see if your 3D printing bed is too high or too low. If the filament doesn’t stick in certain places or the height and width vary across the building surface, you might have issues with your bed being unlevel.
Final Thoughts
Having your 3D printing nozzle too close to the printing bed can result in several issues and prevent you from using the printer. If you notice any symptoms described above, make adjustments until you have things right.
This common issue is pretty easy to fix, so don’t worry if you run into the problem. Turn off the printer, clean it up if you need to, and make the proper adjustments to the nozzle, and you’ll be printing again in no time.
