Hi there! This issue has been recognized and fixed in our recent update. To resolve this, please delete your existing preset (you can use the Batch Preset Management function under the File tab in bambustudio), then re-download and re-import the preset.
Thank you for reporting this issue! We hope you enjoy using the preset—happy printing!

I have the same issue unfortunately. Tried deleting and reimporting the filament, but it didn't help.

Here is an LLM analysis:

---

In AMSMaterialsSetting.cpp, on_select_filament() looks up the selected filament in the preset list and has this check for user-created presets:

for (std::string printer_name : printer_names) {
    if (preset_name.find(printer_name) != std::string::npos) {
        has_compatible_printer = true;
        break;
    }
}
if (!it->is_system && !has_compatible_printer) continue;

printer_names is a set of full printer preset names such as "Bambu Lab X1 Carbon 0.4 nozzle". The check passes only if the preset name itself contains that full string as a substring — skipping the compatible_printers config field entirely.

BambuStudio's own UI always appends the full printer preset name when saving a custom profile (e.g. My Filament @Bambu Lab P1S 0.4 nozzle), so this works for UI-created presets. But Polymaker's profiles use the @BBL X1 abbreviation, which never matches, so the filament type and temperatures are never populated — triggering the error.

Why most other third-party profiles don't hit this

Profiles created via BambuStudio's UI use "inherits" pointing to a system preset and share its filament_id. BambuStudio finds the system preset first in the lookup (which is always trusted), so the check is never reached for them. Polymaker's profiles are self-contained with their own unique filament_id (PMPL07), which is the correct approach for a vendor distributing official presets — BambuStudio just doesn't handle this path correctly.

Workaround (profile side)

Split each profile into one file per printer, naming each one with the full BambuStudio printer preset name:

• Panchroma PLA Matte @Bambu Lab X1 0.4 nozzle
• Panchroma PLA Matte @Bambu Lab X1 Carbon 0.4 nozzle
• Panchroma PLA Matte @Bambu Lab P1S 0.4 nozzle
• Panchroma PLA Matte @Bambu Lab X1E 0.4 nozzle

Each file would have compatible_printers limited to its single matching printer.

Proper fix (BambuStudio side)

Replace the preset-name substring check with a compatible_printers config lookup — consistent with how Popup() already does it:

ConfigOption *printer_opt = it->config.option("compatible_printers");
ConfigOptionStrings *printer_strs = dynamic_cast<ConfigOptionStrings*>(printer_opt);
bool has_compatible_printer = false;
if (printer_strs) {
    for (auto& printer_str : printer_strs->values) {
        if (printer_names.find(printer_str) != printer_names.end()) {
            has_compatible_printer = true;
            break;
        }
    }
}

This bug is present in both the release branch and current master as of April 2026.

Here was the manual fix for a download filament preset, like Panchroma PLA Matte @BBL X1 - BambuStudio.json, so it works for e.g. P1S:

Hi thanks for pointing out the issue. We will check this problem asap. For now you can download bblfmt file for bambustudio.
