Drag your .stl file into the viewer or select it. It stays local on your device.

2 Step 02

Adjust the view

Rotate, zoom, pick material and lighting, align and animate – all in real time.

3 Step 03

Export

Save a high-resolution image (PNG) or a short video (MP4) – perfect for shops, docs or social media.

Use cases

One tool, many jobs.

Everything you can do around your 3D models – from the print check to the product shot.

Check before 3D printing

Inspect geometry, proportions and details of your model before you print it.

Present models

Show a model to clients or colleagues right in the browser – no CAD software needed.

Try materials

Test 18 materials from steel and gold to wireframe and find the best look.

Create media

Produce product images and short animations for your online shop, documentation or social media.

Animated videos

3D model videos for website loops and hologram fans

Need an animated video of your 3D model for a project, a website or a 3D hologram fan – with the right background, specific materials and colours? Instead of tediously screen-recording, you set your model up exactly here and export a clean, smoothly rendered MP4 clip directly.

Animated 3D model as video: a 3D hologram fan shows a free-floating, glowing model, next to a laptop with the same model as a video loop on a website.

Seamless loops for your website

Export short clips with a white or matching background – perfect as a subtle endless loop in your hero area, on product pages or in your portfolio.

Clips for 3D hologram fans

With a black background the tool delivers exactly what hologram fans (3D hologram displays) need: your model floats freely in space, with no visible frame.

Social media clips in portrait and landscape

Export ready-made clips in 9:16 or 1:1 for reels, stories and TikTok – your model perfectly staged, with no video editing.

Product presentation & e-commerce

Show items as rotating 360° clips in your shop, offer or pitch – with exactly the material and colour that match your brand.
