QIDI Max4 Review: A Large-Format 3D Printer Worth $1,599 AUD?

Quick overview

The QIDI Max4 3D Printer is the flagship model QIDI’s Australian storefront leads with — it gets the top hero banner spot on the homepage, promoted as the brand’s high-temperature, multi-material powerhouse. Rather than a compact desktop unit, the Max4 is built around a large 390 x 390 x 340 mm print volume and is positioned to handle demanding, industrial-grade jobs rather than casual hobbyist prints. We went through the product listing, spec details, and bundle options to see what’s actually included at the price.

Key features

  • Large 390 x 390 x 340 mm build volume — enough room for oversized single prints or multiple parts in one job, well beyond typical desktop-class printers.
  • Active cooling air control system — QIDI designed this specifically to reduce clogging during long or high-temperature prints.
  • 2 mm lead Z-axis screw with anti-backlash nut, paired with a 390 x 390 mm ultra-uniform heated bed, aimed at consistent layer accuracy across the full bed area.
  • New-generation leveling sensor — the nozzle itself acts as the sensor, so QIDI says there’s no probe offset to calibrate and no guesswork; it’s also built to stay accurate regardless of bed surface or environmental vibration.
  • AI camera monitoring — actively watches for common print failures like “spaghetti” tangles, so a failed print can be caught early instead of running to completion unsupervised.
  • Smart resonance control with 1.5GT belts, which QIDI positions as its answer to visible ripple lines on printed surfaces.
  • 5-inch touch screen with an upgraded processor and a redesigned UI for on-device control.
  • QIDI Box compatibility — pairing the Max4 with the separate QIDI Box unit (which includes built-in chamber heating up to 65°C) adds multi-color and multi-material printing on top of the base machine.

Who it’s for

The Max4 is built for someone who has outgrown a small desktop 3D printer and wants genuine large-format capability along with print monitoring they don’t have to babysit — the AI camera and automated leveling are both aimed at reducing failed, unattended prints. Because QIDI Box multi-material printing is sold as a separate combo rather than bundled in by default, this is really pitched at buyers who are comfortable planning that upgrade path rather than expecting it out of the box. If your priority is high-temperature engineering filaments and a bigger build plate rather than the smallest footprint on your desk, the Max4’s size and feature set line up with that use case.

Pros and cons

Pros:

  • Large 390 x 390 x 340 mm build volume for bigger or batch prints
  • Nozzle-as-sensor leveling system removes a common manual calibration step
  • AI camera actively flags failed prints instead of running blind
  • Currently discounted $200 off the regular AUD price
  • 30-Day Price Match Guarantee, 14-Day returns, and a full 1-Year warranty included

Cons:

  • At $1,599 AUD and up, it’s a considerably bigger investment than QIDI’s smaller Q2 or Q2C models
  • Multi-color/multi-material printing requires the separate QIDI Box, which raises the real cost of the full setup
  • Its large footprint needs more desk or floor space than a compact desktop printer

FAQ

What’s the actual print volume? 390 x 390 x 340 mm, which QIDI positions as suited to large single prints or multiple parts printed together.

Do I need to manually level the bed? QIDI’s new leveling sensor uses the nozzle itself to sense the bed, which the company says removes probe offset and guesswork from the process.

Can it print in multiple colors or materials? Not on its own — that requires pairing it with the separate QIDI Box, sold either standalone or as part of a Max4 Combo bundle.

What’s covered if something goes wrong? QIDI AU backs the Max4 with a 30-Day Price Match Guarantee, a 14-Day no-reason return window, and 1-Year warranty coverage, alongside ongoing expert tech support.

Bottom line

The QIDI Max4 earns its spot as QIDI AU’s homepage flagship with a genuinely large build volume, an AI camera meant to catch failed prints early, and a nozzle-based leveling system designed to remove a routine calibration step. The tradeoff is cost and footprint — this isn’t a starter printer, and multi-material capability means budgeting for the QIDI Box on top of the base unit. At $1,599 AUD (down from $1,799 AUD) with a price-match guarantee, 14-day returns, and a 1-year warranty backing it, it’s a reasonable pick if large-format, high-temperature printing is what you actually need.
