How to Manually Level a 3D Printer Bed

(Paradigm credit: Tom's Hardware)

Whether you're using a brand new 3D printer for the first fourth dimension or noticing that your prints come out uneven or, fifty-fifty worse, neglect to stick, you demand to level the print bed. Entry-level 3D printers, fifty-fifty those which sit down among the all-time 3D Printers, frequently exercise away with luxuries like colour screens, direct drives and probes for automated bed leveling. Don't worry, learning how to level a 3D printer bed is not hard; it just takes a picayune practice.

"Leveling the bed" is a fleck of a misnomer. Nosotros're actually "tramming" the print surface: making sure the nozzle is at the aforementioned height across the bed at every indicate on the X and Y axis.

Level is a unproblematic, if not precise, word everyone can understand.

The biggest problem when manually leveling a 3D printer bed is finding the right distance betwixt the nozzle and the print surface. Too far and your prints won't stick. Too close and you'll impairment the print surface.

Luckily for those of us stuck with manual 3D printer bed leveling, we don't demand to be laser accurate. We're dealing with fractions of a millimeter, and then pretty darn close will get us the quality we seek.

When Exercise You Need To Level a 3D Printer Bed?

After assembly and before your kickoff print.
After changing the nozzle to make sure the nozzle remains the correct distance from the bed.
In one case a week. Fifty-fifty the best printer can fall out of calibration with apply, so check your level occasionally.
After a failed print. Prints not sticking? Yous might exist out of level.

What Yous'll Need to Level Your 3D Printer Bed

A Piece of Newspaper: This is used to gauge the distance betwixt your nozzle and the print bed. Computer paper is a good choice, just a piece of junk mail or a Mail-It Notation volition work likewise.
Filament: Load your printer with PLA for running a test print. PLA is a commonly used filament and sticks well without fuss. We're using Inland PLA + Orange for this article.
Isopropyl Alcohol : Clean the impress surface earlier leveling. Filament never sticks well to a muddy bed.
Paper Towel: For cleaning the bed.
Slicer App: Y'all'll need to slice your test print – whatsoever slicer will do. We like to use Ultimaker Cura.
Bed Level Test Print: There are several files online, we'll use this one from Thingiverse. Information technology'southward sized for an Ender 3. Y'all can size this one to fit your printer's bed or search for a test that'southward made for your specific auto.
Your 3D Printer: In this article, we're using a Creality Ender 3 Pro FDM 3D printer. The iv-bespeak impress bed is similar to many popular 3D printers on the market today, including the Elegoo Neptune two.

Prepare your Printer

1. Make clean the bed. Lightly scrub the print surface with Isopropyl Alcohol and a newspaper towel to remove fingerprints and any $.25 of leftover filament.

2. Preheat your printer and bed to its normal operating temperature. For PLA, we warm up the printer to 200° on the nozzle and 60° on the bed. Wait at least five to ten minutes to permit the printer blot the oestrus.

Some experts believe it's unnecessary to preheat the bed, every bit the possibility of heat expansion is very small. We adopt to level the bed under the same atmospheric condition nosotros utilize while press.

3. Habitation the printer. This volition have information technology to the 0,0,0 position.

4. Check your printer controls for an option called Bed Leveling, Level Corners or Bed Tramming. This option will move the printer effectually the four corners of the bed while y'all adjust the springs underneath.

A few Ender 3 models come with leveling aids installed. Y'all'll need to select "Disable Steppers," which turns off the stepper motors and allows y'all to push the print head by manus.

Note: Our Ender 3 Pro has been upgraded to Marlin 2 firmware, which added a Bed Tramming routine.

5. Slide the print head (or let the printer do information technology) to the first corner, centered more than or less over the adjustment knob under the bed. Slip a slice of paper under the nozzle.

6. Employ the aligning knob underneath the bed to enhance or lower the nozzle until it barely touches the paper.

Do this for all iv corners and the center. And so do it once more. Leveling the bed is a balancing deed where adjusting i corner can throw off the opposite corner.

Run a Test Impress

1. Load a bed level test impress into your slicer of choice. Since nosotros're using a Creality Ender 3 Pro, we'll use one constitute on Thingiverse chosen "Ender 3 Bed Level". If your printer has a larger or smaller print surface, adjust the x and y coordinates accordingly.

ii. Reduce the Z superlative to 0.4 for a single layer test impress.

3. Clean the bed with Isopropyl Booze and a paper towel.

four. Run the print.

Diagnose the Results

Nozzle is too close. If your nozzle is too close to the bed, it will turn through the filament, causing a rough, uneven surface. Y'all could have sparse patches where the plastic is being pushed into the bed surface. Information technology may exist difficult to remove.

Nozzle is as well far. If your nozzle is too far from the bed, there volition be gaps between the lines of filament. The lines of plastic appear rounded and may non stick to the bed at all.

Nozzle is merely right. When the nozzle is a perfect altitude from the bed, it will appear slightly squished or lightly flattened. Lines volition blend into each other with a uniform appearance. There volition exist very trivial roughness.

If the squares of the test print announced too far or close to the nozzle, make adjustments as needed and re-run the examination print.

3D Printer Bed Leveling Aids

It tin can be difficult to achieve a perfect get-go layer with manual 3D printer bed leveling. Here'due south a few things to try before you give up and buy a BL Affect Car Sensor, which tin be used to do auto leveling on an Ender 3-fashion 3D printer.

Clean the Bed. A squeaky make clean bed is extremely of import for bed adhesion. Fifty-fifty a few fingers prints tin add enough grease to make a print non stick.
Utilize a Raft. Your slicer can identify a mesomorphic first layer down that helps tall or delicate prints stick. The downside is that you'll accept a rough surface on the bottom of your print. You volition observe rafts nether Build Plate Adhesion in Cura and nether Support Fabric in PrusaSlicer. Other slicers take their raft options in other menus.
Use Glue Stick. A washable disappearing glue stick – the purple kind – from the children's craft aisle is a perfect adhesion helper. It lays down a tacky layer that helps filament grip the surface. Lightly smear the mucilage beyond the whole bed, then launder off afterwards iii or iv prints and reapply. The brand doesn't affair, so feel free to stock upwardly during the adjacent Back to School auction.
Shim the Bed. Warped beds are sadly mutual in inexpensive printers. If your bed seems lower or higher in the center – and you lot have a removable print surface – you tin can shim the bed with aluminum foil, masking record or even a Post-It Notation.
