Kimi 3D Make Tutorial with K3.1 Pro

Choose the kind of 3D work you need

Open Kimi 3D Make. In the Chinese-language interface checked on October 24, its type picker offers three options:

For this tray exercise, select 3D 打印 / 3D printing. Sign in if prompted, and check the access or usage conditions shown by your account before starting.

A browser scene, a rendered video, and a model file serve different purposes. Decide which result you want before asking for a detailed scene or animation.

Give Kimi a brief with a checkable result

For a first attempt, use a flat base, a simple outline, and a small number of parts. Specify the outside size and the features that should stay unchanged. Try this prompt:

Create a two-compartment, open-top desk tray intended for 3D printing.

Design dimensions, all in millimeters:
- Outside width: 80
- Outside depth: 50
- Outside height: 30
- Base thickness: 3
- Outer wall thickness: 2
- One centered divider, 2 mm thick, running from front to back

Keep a flat bottom and a rectangular footprint. Join the divider to the base
and the front and back walls. Do not add a lid, feet, lettering, or decoration.

Show the outside dimensions and explain the resulting compartment dimensions.
Provide a downloadable model file if this workflow supports one, and retain
editable parameters or source when available. Tell me what deliverable you
actually created rather than substituting a picture for a model file.

The simple shape makes mistakes easier to spot. Check for two open compartments, a connected divider, and the requested outside dimensions.

For straight walls without fillets, each compartment’s intended inside width is (80 − 2 × 2 − 2) ÷ 2 = 37 mm. The intended inside depth is 46 mm; the usable height above the base is 27 mm. These are calculations from the brief, not proof that the output satisfies it.

Change one dimension and check what stays fixed

Ask for a controlled revision instead of “make it better”:

Revise the same tray. Change only its outside width from 80 mm to 100 mm.

Keep the outside depth at 50 mm, height at 30 mm, base at 3 mm, outer walls
at 2 mm, and divider at 2 mm. Keep two equal compartments.

Recompute the compartment widths. Do not uniformly scale the whole object.
Show the revised dimensions and identify which parameters changed.

If the walls become thicker as the object gets wider, ask Kimi to revise the construction parameters rather than scale the completed shape. If only a label changes, check the actual geometry before continuing.

Check what you downloaded

Use the export choices actually available in your result. A video or Live Photo can demonstrate appearance; a slicer or editor needs a compatible model file. Keep the first and revised versions separately, then reopen both outside the original preview.

This table describes how to handle a result; it does not mean Kimi always exports every listed format. Changing a filename extension does not convert a file.

Review the object in the tool that will use it

For a print, open the actual exported model in your slicer and check:

• The intended outside size after import.
• The base, divider, and walls in the layer preview.
• Unexpected gaps, separate pieces, or internal surfaces.
• Orientation, supports, and small features for your printer and material.

A clean render does not verify a successful print. Fitted or load-bearing parts need more dimensional checks and physical testing than this introductory tray exercise provides. Our 3D printing workflow covers further preparation.

For a digital asset, import the file into the destination editor or engine. Inspect scale, materials, object separation, and geometry you plan to modify. An attractive camera angle can hide an unfinished back or an intersecting surface.

Where Blender fits

Moonshot reports that K3.1 Pro can write and run scripts for Blender and CAD software. This is useful for explicit construction parameters or a repeatable scene setup, and is a separate workflow from the consumer 3D Make interface.

Specify your installed application version, intended dimensions, output folder, and required deliverables. Inspect the script before running it, then verify the files it produces. Reuse the tray brief and revision table as concrete checks. For imports and preparation, see our Blender workflow guide.
