Software / 3D Viewer

3D Viewer for 2D
Image Stacks Free

Turn PNG, JPG and TIF image stacks into fully explorable 3D volumes free of charge. Browse individual planes, render and measure in 3D, clip through structures, overlay multiple datasets, export videos, and generate 3D-printable STL models. Built with HREM data in mind, and equally suited to similar stack image techniques.

Plane Viewer

Browse and visualise individual image planes from a stack in a clean 2D workflow. Designed for simple navigation, quick inspection, and easy resizing and updates while you explore.

Highlights

View slices from PNG/JPG/TIF stacks
Resize and update views easily
Great for checking structure, contrast, and consistency

time.

Volume Viewer

View your image stack in 3D with practical controls aimed at exploration and communication rather than complexity. Useful for cropping, basic measurements, and exporting views.

Highlights

3D volume viewing with clear camera controls
Cropping tools to focus on a region of interest
Simple measurement tools
Colour/appearance controls
Export frames and create videos (where supported)

Transform Images to 3D Printable Models

STL Wizard – turn stacks into 3D-printable models

Generate an STL from a 2D image stack for 3D printing or sharing. Includes tools to improve the output by removing holes and cleaning up results.

Highlights

Create STL directly from image stacks
Hole removal / clean-up tools
Export printable models for demos, teaching, or prototyping

Who it’s for

Made for anyone working with image stacks, including microscopy, engineering inspection, research datasets, teaching materials, and general 3D visualisation from 2D slices.

View a HREM Dataset

Visualise a HREM dataset, convert to a 3D and use the volume viewer with a real stack. This stack is downsized to 10% of the original data and has a voxel spacing of X/Y:6um Z: 3um.
