Capabilities

Everything you need for a convincing 3D packaging preview

Whether you call it a 3D box simulator, carton configurator, or structural packaging preview, these tools help you validate scale, readability, and shelf presence before you commit to plates or samples.

Real-time 3D viewport

Orbit, zoom (scroll or slider), HDRI environments, shadows, and optional grid—ideal for packaging reviews and client sign-off.

Dimensions & units

Set width, height, and depth in millimeters, centimeters, or inches. Scene units convert to centimeters for consistent 3D scale.

PBR material presets

Kraft, white carton, gloss or matte plastic, corrugated, and metallic foil—roughness, clearcoat, and environment response tuned for packaging looks.

Opening mechanisms

Closed view, lid from back, split top flaps (hinge on long or short side), and a swinging door-style left panel—animated open amount.

Per-face artwork & rotation

Upload PNG or JPG per face, rotate in 90° steps, and apply one image to all faces when you need a quick placeholder wrap.

Environment presets

Choose from studio, city, warehouse, sunset, and dawn environments. This is a great way to get feedback on your design.

JSON import & export

Download a single v1 JSON file with dimensions, materials, openings, lighting, zoom, and per-face images (base64)—ideal for backups, handoff to teammates, or moving between machines. Import a file back into the studio to restore the full scene.

Local save & PNG export

Auto-save to browser storage on a short debounce, with explicit save/clear controls. Export a high-resolution PNG snapshot of the live viewport for decks, RFQs, and marketing.

Record presentation

Record a 15-second video of the viewport with audio, then download the MP4 file. This is a great way to share your 3D packaging simulator with your team or clients.

Portfolio

Packaging visuals & motion

Stills and short clips we ship to sell structure, print, and motion in one breath—turntable captures for PDPs, board-and-foil looks for pitch decks, and in-app shots that show how teams actually work inside 3D Box Studio. The grid below mixes photos and video; filter when you only want one format.

Curating your own reel? Drop files under public/showcase/images/ or public/showcase/videos/, list them in manifest.json, and use optional layout: "standard", "tall", or "wide" for wider or taller tiles in the grid. Source lives on GitHub.

Workflow

From flat idea to 3D packaging check in minutes

A lightweight workflow for teams who need a believable 3D box mockup without installing heavy CAD packages.

Set structure & board

Choose outer dimensions, material preset, and how the top or door should open for your 3D carton preview.

Drop in artwork

Map prints to faces, rotate to match portrait or landscape panels, and iterate until the 3D box mockup reads clearly on screen.

Share & save

Export a PNG for decks and RFQs, or rely on local persistence so your 3D packaging simulator session survives refresh.

Frequently asked questions

Straight answers for teams evaluating a browser-based 3D box designer, box maker, or packaging simulator versus desktop CAD.

What is a 3D box designer or packaging simulator?

A 3D box designer lets you preview how flat packaging artwork and structural choices look on a three-dimensional carton or mailer. A packaging simulator applies realistic lighting and materials so stakeholders can review proportions, openings, and branding before print.

Is 3D Box Studio a free 3D box maker?

Yes. 3D Box Studio is a free 3D box maker and design tool that runs entirely in your browser. There is no paywall for dimensions, materials, openings, per-face artwork, HDRI lighting, PNG export, or JSON import/export. Your work can be saved locally without creating an account.

What is 3D box simulation used for?

3D box simulation helps packaging designers, brand teams, and printers validate scale, graphic placement, and opening behavior before committing to plates or physical samples. It is ideal for client presentations, e-commerce mockups, and internal design reviews—not for engineering production die-lines.

Is this a substitute for Esko, ArtiosCAD, or dedicated packaging CAD?

No. Those platforms engineer production die-lines. This 3D packaging simulator helps you communicate look and feel, camera angles, and rough scale early. Export is a viewport PNG, not a print plate.

How is a 3D box design maker different from a mockup template site?

Template libraries give you fixed box shapes with uploaded artwork. A 3D box design maker like 3D Box Studio lets you adjust width, height, depth, materials, lid and flap openings, and per-face graphics in one interactive viewport—better for custom carton sizes and structural previews.

Does the 3D box simulator work on mobile?

The studio is built for desktop browsers with WebGL. Phones may run it, but the control density is optimized for keyboard and mouse users.

Where is my data stored?

Optional local browser storage keeps your fields and encoded images on-device. There is no account-backed cloud sync in this open tool.
