A product prototype for investors: concept board to render

Investors, customers and partners want to see the product. A sketch is not enough, and a photoreal render of a model with real dimensions is far more convincing than a pure AI image, because you can show it from any angle, open it up, and honestly say "this is what we will make".

This playbook follows the whole Concept, Build, Make journey for one product. The example is a compact smart-home sensor, but the method is general.

1. Concept: find the look

On the Concept Board, describe the product and the feeling:

Four concept images of a compact, friendly smart-home air quality sensor. Soft rounded body, a ring of light on top, matte white with a light oak base. Looks like it belongs on a bedside table.

Refine with chips ("Rounder", "More minimal"), mix two images ("A's shape with C's texture"), and pin reference photos to the moodboard. When one direction wins, Lock concept to get a clean turnaround (front, side, top, three-quarter).

Each concept image costs credits (by default 5 in Fast and 8 in Smart), so explore in Fast.

2. Build: add the truth

Now move to Build and turn the intent into real geometry. This step is what makes it credible. Give the agent hard facts:

Build the locked concept. Overall it is 90 mm wide and 38 mm tall. Inside is a 45 mm round PCB and a small fan. The top is a translucent ring for light. The base is a separate piece in oak-colored material. Two pieces, held with three M2 screws.

Confirm you have separate Pieces for anything with a different material or finish. Assign each a material and color, so the Make list and renders are honest.

Check the Parameters the agent assumed from the concept (they carry a "concept" badge) and replace guesses with real values.

3. Make: check what you are promising

Run the manufacturability check for the process you plan to use. Prototypes are typically 3D printed, and production might be injection molded. Be honest about both.

• Does it print without supports?
• Do the pieces fit with realistic clearances?
• Is the wall thick enough for the plan you describe?

If production will differ from the prototype, say so in your deck. Investors respect that more than discovering it later.

4. Render Studio: make it beautiful

In Render Studio you assign materials per piece, choose an environment, and set the camera.

Environment presets: Studio Soft, Desk Lifestyle, Golden Hour, Dark Hero.

Prompt-driven looks let you describe a scene:

Premium product shot on a walnut desk, soft morning light, shallow depth of field, a coffee cup blurred in the background.

Render outputs depend on your plan: 1080p on the trial, 2K on Maker, 4K stills and turntable video on Pro. A 4K render costs 5 credits by default. An optional AI enhancement pass adds a marketing polish for 5 to 8 credits.

You can also produce an exploded view that shows how the pieces fit together, which tells the story of "this is real and buildable".

5. Print a prototype

Export 3MF or STL for each piece, print, sand and paint if you like. A physical prototype in your hand at a meeting is worth a lot. Print the pieces in the orientation recommended by the check, and test the fit before committing to the full set.

6. Create a drawing, if useful

If your audience includes a manufacturing partner, add an auto-dimensioned drawing and a Make list. This tells them you understand cost and process.

7. Share safely

Your design is valuable. Before sharing:

• Keep the Thing private (see Private and public Things).
• Share a view link with an expiry date and, if offered, a password.
• Consider watermark options for shared renders and drawings.
• Send the renders as files if you do not want to give access to the model.
• Tag the commit "investor-demo-v1" (tags are part of the Pro plan's full history tools), so you can always reproduce exactly what they saw.

A pitch-ready asset list

Try it

On the Enclosure template:

Make this look like a polished consumer product: soften all outer edges with a 3 mm radius, add a recessed label area on the lid, and assign matte white to the box and light oak to the lid. Then prepare it for a Desk Lifestyle render.
