Exploded View Animator: Free 3D Collapse, Assemble & Explode Videos
Kick-Start.ai’s free exploded view animator turns multi-part 3D models into short, share-ready videos — parts flying together, pulling apart, building piece by piece, spiraling in, peeling along an axis, or spinning on a turntable. Upload a GLB, GLTF, OBJ, STL, FBX, or a ZIP of separate pieces, choose a style and camera, then download a clip sized for TikTok, Instagram, YouTube, or the web.
Everything runs locally in your browser. Your files are never uploaded, there is no sign-up, and you use no AI tokens — ideal when you want a polished explode/assemble video without Blender timelines or After Effects.
Benefits for makers and marketers
- Ship social clips in minutes. Go from model file to downloadable video without learning animation software or waiting on a render farm.
- Show how products go together. Collapse, sequential build, and spiral styles make assembly clear for prints, kits, bricks, and packaging pages.
- Match the platform. Export portrait (9:16), square (1:1), or landscape (16:9) at up to 1080p so Reels, Shorts, feed posts, and product pages all look intentional.
- Keep designs private. Processing stays on your device — useful for unreleased prints, client kits, and proprietary CAD.
- Work with what you already export. Single multi-part files, Meshy Auto Split exploded meshes, or a ZIP of separate part files all work.
- Stay flexible on any device. Desktop, tablet, and phone layouts supported; Chrome/Edge for WebM, PNG frame ZIP when Safari or mobile capture is limited.
How to make an explode / collapse video
- Add a model — Drop a file, choose multiple part files, upload a ZIP, or try a built-in sample (valve, Rubik’s cube, solid print).
- Check the pose — “Already apart” for Meshy-style exploded exports, or “Already together” for assembled kits and LEGO-style builds.
- Pick a style & camera — Fly together, Pull apart, Build it, Spiral in, Axis peel, or Spin showcase; pair with Orbit, Hero zoom, Slow spin, Crane, or Focus tour.
- Download — Choose length (3–90s) and aspect ratio, then download WebM — or PNG frames ZIP on Safari/iOS.
Who is this for?
3D print creators
Show multi-part prints and AI-generated “parts fly together” clips for Instagram, TikTok, and maker communities. Pair Meshy Auto Split exports with pose Already apart + Fly together for a pro collapse look.
LEGO & brick builders
Export pieces from your build tools and create a quick build or explode montage — no complex keyframe animation required.
Toy & kit makers
Turn product kits into packaging-style assemble videos for Etsy, Kickstarter, Amazon listings, or product pages.
Product marketers & educators
Explain internal structure with an exploded view, then reverse it into an assemble clip for tutorials, landing pages, and ads.
Features
- Auto piece detection (mesh islands) for single-file multi-part models
- Multi-file and ZIP upload (each file = one piece)
- Six motion styles: Fly together, Pull apart, Build it, Spiral in, Axis peel, Spin showcase
- Five camera presets plus motion feel controls (stagger, energy, explode distance)
- Studio lighting, environment maps, shading, part colors, and custom backgrounds
- Works on desktop, tablet, and phone
- Private by design — files stay in your browser session
Formats & tips
| Input | Notes |
|---|---|
| GLB / GLTF | Best choice for web — materials and hierarchy often preserved |
| OBJ | Geometry only (engineering / part colors applied in-tool) |
| STL | Great for prints; solid single meshes work best with Spin showcase |
| FBX | Supported for many DCC and kit exports |
| ZIP | Bundle many part files at once; each entry becomes a piece |
If your model is one solid mesh, use Spin showcase or export parts as separate files. Meshy “Auto Split” exploded exports often work great with pose Already apart + Fly together. For the sharpest 1080p WebM, use desktop Chrome or Edge.
Frequently asked questions
What is an exploded view animator?
An exploded view animator creates a short video where the parts of a 3D model move apart (explode) or move back together (collapse / assemble). Kick-Start’s Exploded View Animator does this in the browser from your GLB, OBJ, STL, FBX, or ZIP files — no desktop animation suite required.
Is the Exploded View Animator free?
Yes. It is free to use in your browser with no signup and no AI token cost. Your models are processed locally on your device and are not uploaded to Kick-Start servers.
Do I need to create an account or install software?
No. Open the page, load a model, pick a style, and download. There is nothing to install beyond a modern web browser.
Are my 3D models private? Do you upload my files?
Your files stay in the browser session on your device. The tool does not upload models to our servers for processing. Clear the page or close the tab when you are done if you want to discard the session.
Which file formats are supported?
GLB and GLTF are recommended. OBJ, STL, and FBX are also supported. You can upload multiple part files at once or a ZIP archive where each file is treated as one piece.
What animation styles can I choose?
Fly together (collapse), Pull apart (explode), Build it (sequential), Spiral in, Axis peel, and Spin showcase. Cameras include Orbit, Slow spin, Hero zoom, Crane, and Focus tour. You can also tune stagger, energy, and explode distance.
How do I make a Meshy “parts fly together” video?
Export or download a multi-part / Auto Split model from Meshy (or similar). Load it here, set pose to Already apart, choose Fly together, pick a camera and aspect ratio, then download. That combination matches the popular collapse look for social posts.
What if my model won’t split into pieces?
Many single STL prints are one connected solid, so there are no separate islands to animate apart. Use Spin showcase for a turntable clip, or upload each part as its own file / ZIP so the tool can treat them as pieces.
Does it work on phones and tablets?
Yes. The layout stacks on phones, supports touch orbit, and can still download a clip. On smaller devices, part and triangle limits are a bit tighter than on desktop. For the sharpest 1080p WebM, desktop Chrome or Edge is best; on iOS Safari, use PNG frames ZIP if video capture is unavailable.
Which browsers work best for video download?
Chrome and Edge on desktop are best for WebM download via MediaRecorder. Safari and some mobile browsers may need the Download PNG frames (ZIP) option, which you can turn into a video in almost any editor.
What export sizes and lengths are available?
Choose aspect ratios for portrait (9:16 — Reels, TikTok, Shorts), square (1:1 — feed posts), or landscape (16:9 — YouTube and web). Clip lengths range from a few seconds up to 90 seconds. Desktop exports target 1080 on the short side; phones may export at 720 for performance.
Can I use this for LEGO, toys, and product kits?
Yes. Export separate pieces (or a multi-part file), set pose to Already together for a pull-apart or sequential build, or Already apart if pieces start separated. The result works well for build montages, packaging videos, and product pages.
Is this a replacement for Blender or After Effects?
No — it is a fast path for short explode / assemble / spin clips. For complex character animation, long cinematic edits, or custom rigs, use a full DCC tool. Use Exploded View Animator when you need a clean product motion graphic in minutes.
How is this different from Flipbook Maker and Pattern Maker?
Exploded View Animator turns 3D models into explode/assemble videos. Flipbook Maker builds VFX sprite sheets from image sequences. Pattern Maker creates seamless tileable patterns. All three are free Kick-Start browser tools that keep your files private.
