Best evidence by path

Failed printSymptom, material, recent change.

Model preparationModel description, target printer, intended use.

Broken partDescription, rough dimensions, load and fit.

Describe the failure.

Start with what you saw. Your symptoms and written details guide the next check.

The symptom

What happened? Required

Describe what you saw, when it started, and what changed. Unknown details are okay. Example: “The first layers looked fine, then the print detached after 20 minutes.”

What are you trying to solve?

Closest symptom (optional)

Not sure of the category? Describe the symptom in your own words; those details still help route the case.

Supporting evidence Optional

Photo submissions are temporarily unavailable. Use your written symptoms for the free preview.

Photo checks and storage

The current analysis path does not inspect photo pixels. It uses your symptom selection, written notes, and fields.

This workflow currently accepts written evidence only. Photo marking in the Evidence Lab stays in your browser.

Have an STL or 3MF instead? Use Check File for mesh evidence after signing in.

Printer & setup

Printer

Material

What changed recently?

FFF build surface and nozzle/bed temperatures (optional)

Build surface

Nozzle temp

Bed temp

Detailed symptom rules apply only after the process is established. Confirmed FFF/filament jobs use FFF checks. Resin/SLA/MSLA/DLP/LCD or photopolymer jobs use vat-process evidence collection without FFF nozzle, bed, brim, extrusion, or Z-offset instructions. If the process is unknown, the result asks you to identify it before applying settings advice.

Routing: first-layer clues go to the first-layer diagnosis, failure symptoms go to failed-print diagnosis, and plain questions get the general print answer path.

Preview the key finding, then decide. Free preview returns the rule-based key finding and next-check guidance. Free preview does not use a credit. Sign in before requesting Premium Analysis; account access is checked before a full plan. Premium Analysis may send your written case details and rule-matched findings to the configured AI provider to select a hypothesis. It does not send the uploaded photo or model bytes to AI. The rule-based plan remains available if AI is unavailable.

Plan a better-fitting part.

Build a measurement, CAD, and fit-prototype checklist. This tool does not create CAD or a replacement file.

Photo reference Optional

Photo submissions are temporarily unavailable. Use your written measurements and description for the free preview.

Photo storage and analysis boundary

The current plan uses the written measurements and description. Photo submission and storage are unavailable in this workflow.

How to photograph and measure the part

Illustration, not a measured part. Photograph the whole part and the surface it fits against; keep a ruler in the same plane. A photo helps explain shape, but cannot establish an accurate fit.

Record measured values when possible. Mark estimates and unknowns, include units, and measure hole spacing center to center. For a load-bearing, hot, electrical, or safety-critical part, get qualified review before making or using a replacement.

Part & measurements

What broke? Required Measurements you have

Include units (for example, mm) and say which values are measured, estimated, or unknown. For hole spacing, state whether you measured center to center.

Measurements are required to validate fit. Label each size, screw spacing, and thickness as measured, estimated, or unknown.

Use & fit

How is it used?

Material need (optional)

Do you still have the original part? Anything else that may help?

Diagnose the failure

Start with what you saw. Symptom words help route the case even when you are not sure of the category.

Browser-only drafts Each form shows its browser draft status. Text and selections may be kept for up to 7 days; uploaded files are excluded. Delete drafts on a shared device.

Saving and recovery details

Text and selections can be saved in this browser about 2 seconds after an edit, or immediately with Ctrl+S (Command+S on macOS); browser drafts are configured to expire after 7 days and may be removed earlier by browser or site-data cleanup. If an eligibility screen interrupts submission and a current browser draft is still available, the page attempts to restore its saved text and selections in this tab; review them before continuing. The current browser-draft schema is designed to omit uploaded-file bytes. Attachments are currently unavailable. After a signed-in submission succeeds, the resulting Print Case is stored under the applicable access and retention rules. Anyone using this browser profile can see browser drafts, so delete them when using a shared device.

Already trust the STL or 3MF?

Use Check File when you have the model ready and want the Print Score report now. Print Analysis questions do not attach a model unless you use a workflow with an upload box.
