Bambu Lab 3D Printer Setup: First Print Guide

This guide walks you through setting up a Bambu Lab 3D printer for your very first print, from unboxing to a successful finished object. You’ll learn how to prepare the printer, load filament, run the initial calibration, and start a print using the Bambu Handy app or Bambu Studio software. By the end, you’ll have a completed print and the confidence to start your own projects.

What You’ll Need

Bambu Lab 3D printer (e.g., X1, P1, or A1 series) with its power cable
Filament (PLA is recommended for your first print)
Bambu Lab starter kit contents: glue stick (for textured plates), spare nozzle wiper, and hex wrenches
Smartphone with the Bambu Handy app installed, or a computer with Bambu Studio installed
Stable Wi-Fi network (2.4GHz or 5GHz) and the printer’s network credentials
A clean, flat, well-ventilated area with space around the printer

Step-by-Step

Unbox and place the printer. Remove all packing tape and foam. Place the printer on a stable, level surface, leaving at least 10 cm of clearance on all sides for ventilation and cable movement. Do not remove the protective film from the build plate yet.
Install the build plate. Open the front door (if your model has one) and slide the build plate onto the magnetic bed. Ensure it clicks into place and sits flat. Remove the protective film now.
Power on the printer. Connect the power cable to the back of the printer and plug it into a wall outlet. Press the power button on the front or side. The screen will light up and show a boot sequence.
Set up the printer on the touchscreen. Follow the on-screen prompts to select your language, connect to Wi-Fi, and sign in to your Bambu Lab account. If you don’t have an account, create one on the printer or in the app. The printer will automatically check for firmware updates and install them if needed.
Load the filament. Take your PLA filament spool and remove any tape or clips. Open the filament spool holder on top of the printer. Place the spool on the holder with the filament unwinding from the front. Cut the filament tip at a 45° angle to make it easier to insert. Heat the nozzle by selecting “Load” on the screen, then insert the filament into the filament entry port until it catches and feeds automatically. Wait until the printer confirms the filament is loaded.
Run the initial calibration. The printer will prompt you to run a calibration routine. This includes bed leveling, vibration compensation, and nozzle cleaning. Select “Calibrate” and let the printer complete the process. This takes about 10–15 minutes. Do not interrupt it.
Prepare a print file. On your smartphone or computer, open Bambu Studio (or the Bambu Handy app). Choose a pre-loaded model from the “Gallery” or “Example” folder, or import your own STL file. For your first print, pick something simple like a small benchy or a calibration cube.
Select the correct printer and filament. In the slicer, ensure your printer model is selected (e.g., “Bambu Lab X1 Carbon”). Choose the filament type as “Bambu PLA Basic” or “Generic PLA” if you’re using a third-party brand. The slicer will automatically set the appropriate temperatures and speeds.
Slice and send the print. Click “Slice” to generate the G-code. Then click “Print” and choose to send the file to your printer via Wi-Fi. Alternatively, you can save the G-code to an SD card and insert it into the printer’s card slot. The printer will start heating up and begin printing after a short countdown.
Monitor the first layer. Watch the first few layers closely. The filament should stick to the plate smoothly. If the first layer looks squished or too thin, or if it’s peeling off, stop the print and adjust the z-offset (see Troubleshooting). If it looks good, let it continue.
Wait for completion. The printer will notify you when the print is done. Open the door (if applicable) and carefully remove the print from the build plate. The plate may be slightly warm; use the provided scraper if needed. Let the print cool before handling.
Clean up. Remove any filament ooze from the nozzle using the wiper. If you used a glue stick, clean the build plate with warm water and a mild soap, then dry it completely before the next print.

Common Mistakes

Skipping calibration: Running the printer without calibration leads to poor adhesion and layer shifting. Always let the printer finish its self-check.
Using wet filament: PLA absorbs moisture from the air, causing bubbles and stringing. Store filament in a dry bag or airtight container with desiccant.
Incorrect build plate type: Using the wrong plate for the filament (e.g., PLA on a cold plate without glue) can cause warping. Check the recommended plate in the slicer.
Not removing the protective film: Forgetting to peel the film off the build plate ruins adhesion and can damage the plate.
Forcing filament: Pushing filament into the nozzle too hard can jam it. Let the printer feed it automatically.
Ignoring the first layer: Walking away before the first layer is down can result in a failed print that wastes time and filament.

Tips

Use the included glue stick on the textured PEI plate for PLA prints—it makes removal easier and prevents adhesion issues.
Keep the printer in a room with stable temperature (18–25°C) and low air drafts to prevent warping.
For your first few prints, use the pre-sliced models in the Bambu Handy app—they’re optimized for the printer.
Learn to use the “Live View” in the app to monitor prints remotely and spot problems early.
After each print, wipe the nozzle with the silicone wiper to remove residue—this keeps extrusion consistent.
If you’re using a third-party filament, start with a temperature tower to find the ideal temperature for that brand.

Troubleshooting

First layer not sticking: Clean the build plate with isopropyl alcohol (or warm soapy water) to remove oils. Re-apply glue stick. If the nozzle is too far from the bed, adjust the z-offset in the printer settings (lower the offset by 0.05 mm).
Print is stringy or has blobs: This usually means the nozzle temperature is too high or the filament is wet. Lower the temperature by 5–10°C and dry the filament in a filament dryer at 50°C for 4 hours.
Layer shifting or ringing: The printer may be on an unstable surface. Ensure it’s on a solid table. Re-run vibration calibration from the printer menu.
Nozzle clogging: If the filament stops extruding, heat the nozzle to 250°C and use the “Unload” function to pull out the filament. If that fails, use the provided needle to clear the nozzle from the bottom.
Wi-Fi disconnects: Move the printer closer to your router or use a Wi-Fi extender. Check that the printer’s firmware is up to date.
Print fails halfway: Check the filament spool for tangles. If the print detached from the bed, re-level the bed and increase the bed temperature by 5°C.

Frequently Asked Questions

Do I need to use Bambu-brand filament?

No, you can use any 1.75mm filament. The slicer has profiles for generic PLA, PETG, ABS, and more. Just select the generic profile and adjust temperatures if needed.

How long does the initial setup take?

From unboxing to first print, expect about 30–45 minutes, including calibration. The calibration itself takes about 10–15 minutes.

Can I print without the Bambu Handy app?

Yes, you can use the printer’s touchscreen to select and print a few pre-loaded models, but for full control and custom slicing, you’ll need Bambu Studio on a computer.

What is the best build plate for PLA?

The textured PEI plate is great for PLA—it provides good adhesion and is easy to remove prints. The cool plate also works but requires glue stick.

How do I update the printer’s firmware?

The printer checks for updates automatically when it’s connected to Wi-Fi. You can also manually check in the settings menu under “Device” > “Firmware Update”.

Why is my print coming out with a rough surface?

This is often due to over-extrusion. In Bambu Studio, reduce the flow rate by 5% in the filament settings. Also check that the nozzle isn’t partially clogged.
