3D Printer Phrozen Sonic MEGA 8K V2

The Phrozen Sonic Mega 8K V2 is a large-format resin 3D printer designed for those who need to combine size and high-resolution printing without compromise. With 43-micron precision and a build volume of 330 × 185 × 400 mm, it is the reference tool for design studios, professional prototyping, architecture, scale models and special effects. Available on pre-order basis.

Technical specifications

What it is used for

The Sonic Mega 8K V2 is designed to print large parts with a level of detail normally associated with smaller formats. Its combination of volume and resolution makes it particularly useful in professional and semi-professional environments where final quality is non-negotiable.

• Industrial and product prototyping with high detail fidelity
• Medium and large-scale architectural models
• Models for special effects (FX) and audiovisual production
• Digital sculpture and master production for silicone or resin moulds
• Large-format dental and medical parts (with certified resins)
• Production of collectible figures and miniatures in small runs
• Jewellery and accessory design at enlarged scale
• Functional validation of CAD designs prior to final manufacturing

How to use it

1. Download and install CHITUBOX (free) and set up the printer profile for the Phrozen Sonic Mega 8K V2.
2. Import your 3D file in STL, OBJ or another compatible format. Orient and support the model according to the part's requirements.
3. Slice the model by adjusting layer height, exposure times and the specific parameters of the Phrozen Aqua-Gray 8K resin or another compatible resin.
4. Export the sliced file and transfer it to the printer via USB or Ethernet.
5. Pour the resin into the vat, making sure the PFA (nFEP) film of the Mega 8K vat is in good condition and correctly installed.
6. Start the print from the touchscreen and monitor the first layers to verify adhesion to the build plate.
7. Once printing is complete, carefully remove the build plate and detach the parts using the included spatula.
8. Wash the parts with isopropyl alcohol 99.9% for the time recommended by the resin manufacturer.
9. Cure the parts under UV light in a suitable curing station until the polymerisation process is complete.

Usage tips

Vat film maintenance

The PFA (nFEP) film is the component that accumulates the most wear in any resin printer. Inspect it before each long session: if tension marks, excessive opacity or micropores appear, replace it. For the Sonic Mega 8K V2, use the PFA film 450 × 280 mm specific to this vat. A worn film is the most common cause of print failures and parts stuck to the bottom.

Orientation and supports for large parts

With a build volume of 330 × 185 × 400 mm you have room to orient parts strategically. For elongated models, tilting the part between 15 and 45 degrees relative to the build plate reduces peel forces on each layer and improves surface quality. Generate medium and dense supports in areas of greatest mass. Avoid printing large flat surfaces parallel to the film, as they increase the risk of delamination.

Resin agitation and temperature

Before pouring the resin into the vat, shake it well for at least one minute to homogenise the pigments and photoinitiators. If you work in a workshop at temperatures below 20 °C, gently warm the resin bottle by submerging it in warm (not hot) water for a few minutes. Cold resin has higher viscosity and can affect levelling between layers and optimal exposure times.
