How to select filament and filament profiles

The Cloud Slicer uses filament selections and slicer filament profiles to generate G-code. This guide explains what each one means and how to choose the right filament setup before slicing.

Filament and filament profiles are different

In the Cloud Slicer, there are two related pieces:

The filament is what you are printing with. The filament profile is what the slicer engine uses for settings such as nozzle temperature, bed temperature, cooling, flow, and retraction.

This matters because normal SimplyPrint filament or spool details do not automatically replace the slicer engine's filament profile settings. The temperatures used while slicing come from the selected slicer filament profile.

Select a filament

1. Open Slicer in SimplyPrint.
2. Find Filaments in the Cloud Slicer sidebar.
3. Click an existing filament card, or click Add filament.
4. Choose the filament you want to use.

The selected filament appears as a numbered card. The number is used by the slicer to identify the filament or extruder assignment.

Select a filament profile

After choosing a filament, check the filament profile shown below it.

1. Click the filament profile selector.
2. Choose a profile that matches the filament type and printer setup.
3. If needed, use the edit button to adjust a custom profile.
4. Save profile changes before slicing.

Profiles may be grouped as user, organization, partner, or system presets depending on what is available to your account.

Select the print profile

The print profile selector is below the filament section. It controls print behavior such as layer height, speed, infill, walls, and supports.

Print profiles are mainly filtered by:

• The selected slicer engine
• The selected machine profile
• The selected nozzle diameter
• The selected nozzle volume type

Custom print profiles can also be limited to specific custom slicer filament profiles. When that link is configured, changing a custom filament profile can hide or switch away from print profiles that were saved for a different custom filament profile.

System filament profiles do not normally create this print-profile filter. If the print profile you expected is missing, first check the selected engine, machine profile, nozzle setup, and whether the print profile was saved for a specific custom filament profile.

Add more filaments

You can add more filament cards when preparing multi-color or multi-material prints.

Use additional filaments when:

• Different objects should use different colors
• Parts of a model need different filament assignments
• A multi-material printer needs more than one filament available
• You are using color painting or assigning filament to objects

For single-color prints, one filament is usually enough.

What the displayed temperatures mean

The temperatures shown under the filament come from the selected slicer filament profile.

If the values are not what you expect, edit or change the slicer filament profile. Changing a SimplyPrint filament spool's stored details is not the same as changing the slicer profile used to generate G-code.

If filament profiles are missing

If you cannot find a filament profile, check:

• The selected slicer engine
• The selected printer or machine profile
• The selected nozzle diameter
• The filament type
• Whether the profile was created for another engine
• Whether your account has permission to see system or organization profiles

The Cloud Slicer shows compatible profiles for the current slicer setup. Changing the engine, printer, nozzle, or filament type can change which profiles appear.

Changing the print profile does not normally change which filament profiles appear.
