Material profiles in GingerSlicer

A material profile in GingerSlicer stores all the per-material settings for the G1: temperature zones, flow calibration, speed limits, additives, and cooling. Getting the profile right for each pellet is the main calibration task before printing.

Where profiles live in the UI

Material profiles are accessed from the Pellets panel in the Prepare tab (the middle column). Click the material name to open the profile list, or click the settings icon to edit the currently selected profile.

Profiles are stored locally on your machine. They are not automatically synced between computers — see Importing and exporting profiles below.

Key fields in a pellet material profile

Temperature zones

Three temperature inputs corresponding to the G1 barrel zones:

Field (slicer label)	Zone	What to set
Extruder 0	Feeding Zone	Softening temperature — usually 10–20°C below melt
Extruder 1	Melting Zone	Full melt temperature — follow supplier datasheet
Extruder 2	Nozzle Zone	Final viscosity — usually same as or slightly below Melting Zone
Bed	Bed heater	Material-specific adhesion temperature

See Multi-Heating Zones for zone positions and hardware context.

Rotation Volume

The most important G1-specific parameter: mm³ of material per screw revolution. This must be calibrated for each material and nozzle combination — do not copy values between materials without re-calibrating.

See Rotation Volume calibration for the measurement procedure.

Max Volumetric Speed (MVS)

The safe ceiling for extrusion rate in mm³/s. Exceeding this causes the extruder motor to skip. Start conservatively (200–250 mm³/s), then increase after adding SmoothFlow.

See Max Volumetric Speed for how to find your material’s limit.

SmoothFlow

SmoothFlow is the Ginger Additive liquid lubricant added to pellets before loading. It significantly reduces screw friction and raises the achievable MVS.

If you are using SmoothFlow, note the percentage in the profile description so you can reproduce the same mix. SmoothFlow changes the flow behavior, so MVS and Rotation Volume should be calibrated with SmoothFlow applied, not on dry pellets.

See SmoothFlow for dosing and usage guidance.

Cooling

Fan settings are material-specific. Key fields:

• No Cooling for First Layers: set to at least 4 — early layer cooling causes poor bed adhesion
• Fan Speed: start at 0%, increase only if small features deform
• Min Layer Time: slows the print on short layers; 10–15 s for PLA, 5–10 s for PETG

Naming convention

Use a consistent name so profiles are easy to identify when you have many materials:

[Supplier]_[Polymer]-[Grade]_[Variant]

Examples:

• Formfutura_PETG-GF_20pct
• Formfutura_rPLA_batch-2026-04
• Generic_PLA-virgin

Include batch information in the name or description when the supplier ships inconsistent batches. Different batches of the same material can differ by 5–10% in Rotation Volume.

Importing and exporting profiles

To export a profile for backup or sharing with another machine:

1. Open the material profile in GingerSlicer
2. Click the export (save) icon or go to File → Export → Export Config
3. Save the .json file

To import on another machine:

1. Go to File → Import → Import Configs
2. Select the .json profile file
3. The profile appears in the Pellets list and can be assigned to the G1 printer

Note

Imported profiles retain all calibrated values (Rotation Volume, MVS, temperatures). You should still verify Rotation Volume on the receiving machine if the nozzle diameter differs.

Starting from Ginger’s default profiles vs. creating from scratch

Start from a default profile when:

• Ginger Additive ships a pre-tuned profile for your material (check the GingerSlicer profile library)
• You are printing a Ginger-recommended material (PLA virgin, PETG clear, rPLA, PETG GF)

Create from scratch (by duplicating the closest existing profile) when:

• The material is not in the default library
• You are printing a specialty or third-party pellet
• You need a batch-specific calibration separate from the generic profile

Never edit a default Ginger profile directly — always duplicate first, rename, then modify the copy. This preserves the reference profile.

---

When to create a new profile vs. when to use overrides

Use a new profile when:

• The material is genuinely different (different polymer family, different supplier, significantly different processing window)
• You want to keep a stable reference for a specific batch

Use Setting Overrides within an existing profile when:

• You need a small adjustment for a specific print geometry (e.g., different retraction length for a tall thin part)
• You are testing a parameter change and do not want to permanently alter the calibrated profile

Setting Overrides are per-profile fields in GingerSlicer that override base values without changing the underlying calibration. This keeps the base profile clean and makes it easy to revert.
