Free 3D biology illustrations and scientific figure maker

BioLender lets you build biology in 3D — cells, organs, molecules, lab animals and lab equipment — then lay out journal figures, graphical abstracts, posters and slides in 2D. It runs in your browser, free, with no account.

What you can make

Journal figures

Multi-panel figures with panel letters, arrows, labels and charts, exported at 300–600 dpi.

Graphical abstracts

Mechanisms and workflows built from real-looking 3D models instead of flat clip art.

Posters and slides

A1–A4 posters and 16:9 slides; PowerPoint export keeps every item editable.

Teaching material

Anatomy, histology, microbiology and lab-protocol pictures from any angle.

3D models and videos

Turntables and camera moves saved as MP4, or .glb models to spin during a talk.

Lab protocols

Ready-made experiment scenes with lab equipment, hands and gloves.

Two studios

The 3D Studio is where you pick items from the library, pose them, colour them and choose the angle. It is built on a Blender-style engine, so you can go as deep as reshaping a model point by point — but you never have to.

The Figure Studio is a page editor like PowerPoint or Canva: place pictures from the library or the 3D view, turn library pictures in 3D right on the page, add 70 shapes, draw your own, write text with sub- and superscripts, lists and word art, and line everything up.

The library: 16,000+ ready-made models

Every item is a real 3D model you can turn to any angle and recolour. Real structures load straight from the Protein Data Bank, AlphaFold, PubChem and the Human Reference Atlas.

DNA & proteins 7,268

DNA, RNA, gene editors, nucleic-acid drugs, 2,300 real PDB structures and 4,857 AlphaFold human proteins.

Molecules 4,581

Approved drugs, natural compounds, metabolites, lipids, dyes and any PubChem molecule by name.

Human anatomy (3D atlas) 1,094

Every bone, muscle, vessel, nerve and organ of the body, as single parts, systems or regions.

Viruses & microbes 749

Viruses with true capsid geometry, ~330 bacteria on 40 culture media, fungi, protists and parasites.

Props, tools & effects 620

Hands holding lab items, lamps and glows to show redness or heat, tools, clinic items, signs and symbols.

Instruments & engineering 394

Physics, chemistry, biomedical, mechanical, electronics and field-biology equipment.

Nanoparticles 346

Liposomes, mRNA lipid nanoparticles, polymer, gold, silica, iron-oxide and carbon particles.

Body & development 209

Clinical body figures with visible signs of disease, embryos, fetus and model organisms.

Cells 206

Animal, plant, blood, nerve, immune, stem and cancer cells, plus common lab cell lines.

Lab & labels 203

Lab equipment with working states, microbiology kit, arrows, panel letters, charts and timelines.

In vivo models 136

Lab mice and rats, mouse experimental models, procedures, tumour models, imaging and housing.

Diseases & pathology 207

Disease models for every specialty, many on real organs: dental disease, arthritis, fractures, spine disease, stroke, cirrhosis, cancers…

In vitro & cell culture 105

Cell lines by shape, cultures, immunofluorescence, spheroids, organoids and assays.

Tissues & histology 99

Telescoped tissue blocks and histology for every organ system.

Organs 99

Illustrated organs and 81 anatomically exact reference organs.

Biomaterials & devices 103

Hydrogels, scaffolds, dental and orthopaedic implants, joint replacements, microneedles, stents, organ-on-a-chip and dosage forms.

Questions

Is BioLender free?

Yes. It runs in your web browser with no installation and no account.

Can I use the pictures in my paper, poster or slides?

Yes. Export a high-resolution TIFF (up to 600 dpi) or PNG for journals, or an editable PowerPoint or SVG. Some library items are built from open data that asks for a credit line — BioLender lists the exact lines for your figure under Figure credits.

Can I edit the exported figure in PowerPoint or Illustrator?

Yes. PowerPoint and SVG exports keep every picture, shape, arrow and text box as a separate object, so you can move, recolour, retype or delete items one by one in PowerPoint, Keynote, Google Slides, Illustrator, Inkscape or Figma.

Is it a BioRender alternative?

BioLender does the same job — scientific figures from ready-made biology pictures — and adds a real 3D studio: you can turn any model to any angle before placing it.

Do I need 3D experience?

No. Pick an item from the library, turn it with the mouse and press Save picture. The full Blender-style editing tools are there when you want them.

Where are my projects stored?

On your own device, in your browser. Nothing you build is uploaded.
