Asteroid 216 Kleopatra STL

A small official NASA asteroid mesh that passed PrusaSlicer only after its maximum dimension was increased to 50 mm and support plus a brim were enabled.

Direct answer

The source STL is not an honest one-click print at its original scale. In PrusaSlicer 2.9.6, a 50 mm maximum dimension, automatic supports, and a 5 mm brim produced a no-warning G-code export. A physical print has not been verified.

Failure boundary

What did not pass cleanly?

Original source size: the approximately 9.74 mm model exported G-code but triggered a low-bed-adhesion warning.

Default 50 mm slice: it still triggered collapsing-overhang, low-bed-adhesion, and loose-extrusion warnings.

Meaning: the file may be useful, but its required scale, support, and brim settings must stay attached to the download. Browser visibility alone is not print proof.

Evidence ladder

What Image3D verified — and what it did not

Mesh ParsedPassed

4,092 facets, one part, and a manifold mesh were reported.

Slicer TestedPassed with adjustments

PrusaSlicer 2.9.6 exported G-code with zero final warnings under the qualified settings.

Print TestedNot tested

No Image3D physical print, printer-specific result, material result, or dimensional accuracy claim exists.

Source and use boundary

Why the NASA record stays attached

The exact source folder, file hash, attribution, and current NASA media-policy record remain part of the evidence packet. Image3D does not imply NASA sponsorship or endorsement, and production rehosting still requires its item-level source check.

Frequently asked

Printability questions

Is it ready at the original size?

No. The original-size slice produced a low-bed-adhesion warning.

What settings passed?

50 mm maximum dimension, 0.20 mm layers, 15% infill, automatic support, and a 5 mm brim.

Was it physically printed?

No. The correct state is Slicer Tested with required adjustments, not Print Tested.

Three recorded slicer runs

What failed, then what passed

A clean export is meaningful only when the failed defaults stay visible. All three runs used the exact STL and PrusaSlicer 2.9.6.

After download

Eight checks before sending it to a printer

Your printer, material, nozzle, orientation, and desired finish can change the result.

Verify the file hash

Confirm the STL matches the exact file validated here.

Set the intended scale

Start from the recorded 50 mm maximum dimension.

Select your real printer

Replace the generic profile with your printer and nozzle.

Choose the material

Re-evaluate temperature, cooling, and adhesion.

Inspect orientation

Choose the footprint that best fits your quality goal.

Review supports

Inspect every contact and its removal path.

Read every warning

Do not transfer this zero-warning result blindly.

Check layer preview

Look for islands, gaps, and loose paths.

Provenance, rights, and integrity

The source record stays with the file

NASA describes its 3D resources as free to download and use under its current media guidelines. This page does not label the file CC0.

Use boundary

Acknowledge NASA as the source, check the exact record for third-party material, and do not imply NASA endorsement. Read NASA media guidelines.

Exact file identity

Use the checksum to confirm that a transferred copy is the same STL Image3D inspected.
