A 3D printer setup checklist covers six jobs in order: unbox and remove every transport lock, assemble and power on, clean the print surface, load filament, run the printer's calibration, then start with a built-in test print and watch the first layer.

Research-based guide. This article is compiled from manufacturer documentation and has not been checked on a test printer. Treat every figure as a starting point and follow your own printer's manual where it differs.

What is the 3D printer setup checklist for a new machine?

Work through it in this order. Each step is backed by maker documentation, mostly Bambu Lab's A1 guides and Prusa's preflight check, so exact menus differ on your model. Use your manual for specifics.

Where should you set up a 3D printer?

Pick a flat, sturdy surface with room around the printer and air that moves. The where to put a 3D printer guide covers space, noise and ventilation in detail, and 3D printer safety basics covers heat and fire precautions. Place the printer where you can see it, because the first few prints deserve supervision.

How do you unbox and remove the transport locks?

Lift the printer the way the manual shows, then remove every lock, tie and piece of foam before powering on. Bambu Lab's A1 unboxing guide has useful, specific examples:

  • Lift the machine by the handles on the plastic bag, and do not support the X-axis by hand. Hold the Z-axis bracket instead (Bambu Lab).
  • When lifting the base, do not hold the heatbed. Lift the whole plastic base.
  • Unlock the heatbed by cutting a zip tie, and cut the zip ties and cardboard around the toolhead and X-axis.
  • If there are stoppers on the Z-axis, a hex wrench removes them. The guide notes that newer packaging may differ, so follow the unit you receive.
  • Check the labels on the bed and screen for protective film that needs peeling. Bambu Lab says packaging varies between shipments, and that some printers had film on the heatbed surface while the latest do not.

Keep the box and foam until the warranty period and your first month are over, in case of a return or fault. Check the accessory list against the quick start guide, which for the A1 includes a spare filament cutter, hex keys, a scraper blade and a unclogging pin tool.

How do you power on and run the first-time prompts?

Plug in, switch on, and follow the screen. Bambu Lab's guide says that after powering on, the on-screen prompts handle initialization and calibration, and you can connect to the network and the phone app later if you skip them.

Before pressing anything that moves the toolhead, check that cables are clear of the moving parts. Bambu Lab's A1 guide gives cable-organizer advice for exactly that reason: loose cables can sag and scrape the heatbed.

Do you need to clean the print plate on a brand-new printer?

Yes, a quick wipe is worth it. Prusa's preflight check says any dirt can damage both the heatbed and the print sheet, and that a greasy sheet is the number one cause of prints detaching. If you have touched the surface, degrease it with isopropyl alcohol. Bambu Lab's A1 first-print guide says that once the filament is loaded and the build plate is in place, you can proceed.

Follow the plate-specific rules in how to clean a 3D printer bed, because the right cleaner depends on the surface.

How do you load the first filament?

Feed it in until the extruder grips it, then use the printer's load function and confirm that plastic flows from the nozzle. Bambu Lab's A1 steps are a good model:

  1. Insert the filament into the PTFE tube and push it into the toolhead until it stops.
  2. Choose Load on the screen. The nozzle heats to 250 degrees Celsius.
  3. Push the filament in again by hand once the nozzle is hot.
  4. Watch the nozzle. When it extrudes smoothly, confirm on the screen. If unsure, retry.

Other printers use different temperatures and menus, so check the manual. For swapping later, see how to change filament, and for choosing a first material, types of 3D printer filament.

Which calibration should you run on a new printer?

Run whatever the printer offers for bed leveling and vibration, then check the first layer. Bambu Lab describes auto-calibration as automatically adjusting bed leveling, nozzle height, vibration compensation and motor noise using sensors, and recommends running it after moving the printer, after firmware updates or maintenance, after changing hardware and when print quality drops.

Printers without automatic leveling need manual steps; see how to level a 3D printer bed, auto bed leveling explained and how to calibrate a 3D printer.

What should your first print be?

Use the file that came with the printer. Bambu Lab's A1 guide points to the built-in files on the microSD card, and recommends enabling the bed leveling and flow dynamics calibration options before printing. It also warns that after unpacking, the heatbed may have been stationary for a long time, so friction can be high on the first layer, and recommends moving the heatbed by hand to its maximum position first.

Watch the first layer from the start, and read how to send a print to your 3D printer for the file transfer options. If lines lift or look see-through, stop and read fix a bad first layer. When a print finishes, remove it carefully. After that, slice your own model with how to slice a 3D model and the full workflow in how to 3D print.

What else is worth buying early?

A scraper, a spare nozzle and a few basic tools cover most early needs. The 3D printer starter kit page lists accessories worth owning, and how to replace a 3D printer nozzle explains the one job you will eventually need to do.

Frequently asked questions

What do you need to do when you get a new 3D printer?

Set it on a stable surface, unbox it and remove every transport lock, zip tie and foam piece. Assemble and connect it per the manual, power on and follow the on-screen initialization and calibration prompts. Clean the print plate, load filament until you see clean extrusion, then run the printer's calibration. Finally, print the built-in test file and watch the first layer closely. Bambu Lab notes that packaging differs between shipments, so follow the unit you receive and your own manual. Keep the box until you are sure everything works.

Do you need to calibrate a new 3D printer?

Usually yes, and many printers do it for you. Bambu Lab describes auto-calibration as adjusting bed leveling, nozzle height, vibration compensation and motor noise using sensors, and its A1 guide says the on-screen prompts after first power-on handle initialization and calibration. It also recommends recalibrating after moving the printer, after firmware updates or maintenance, after changing hardware and whenever print quality drops. Printers without sensors need manual bed leveling, so follow the steps in your manual and check the first layer.

How do you load filament into a new 3D printer?

Feed the filament into the extruder until it stops, then use the printer's load function and watch the nozzle. On the Bambu Lab A1, you insert filament into the PTFE tube and push it into the toolhead until it stops, choose Load, push it in again once the nozzle heats to 250 degrees Celsius, and confirm only when it extrudes smoothly, retrying if unsure. Other printers use different temperatures and menus, so check your manual for the exact numbers before heating the nozzle.

What should you print first on a new 3D printer?

Use the test file supplied with the printer. Bambu Lab's A1 first-print guide points to the built-in files on the microSD card and recommends enabling the bed leveling and flow dynamics calibration options. It also advises moving the heatbed by hand to its maximum position first, because a heatbed that sat unused during shipping can have extra friction on the first layer. Stay with the printer during the first layer so you can stop the job if lines do not stick.
