Aster BioSlicer is built for manufacturing human tissue

One parametric model drives extrusion and light-based systems alike. Describe a construct in plain language or draw it yourself, then edit any feature, preview every layer, and export to your biofabricator.

The BioSlicer workspace: a layer-types panel set to Voronoi foam over concentric, beside a 3D view of the resulting lattice

Generate complex internal geometries with ease.

Describe it, and it builds

Type the construct you want in plain language. BioSlicer resolves it into real geometry: dimensions, infill pattern and density, channel count and placement. Then refine it conversationally and the model rebuilds against the new spec.

The same conversational layer runs across the whole platform. Meet Bombus, the assistant inside Capitula →

On extrusion, you control every path

Where material is deposited by a nozzle, the toolpath is the design. BioSlicer treats it that way, down to the individual segment.

Advanced path control

Speeds up the design of multi-material and tissue-specific constructs and microarchitectures.

Adaptive channel infill

Route perfusion channels through a construct in any pattern.

Coordinated dual extrusion

Print two materials in one construct, with paths generated adaptively to hit a target deposition ratio.

Graded material transition

Blend two materials gradually across the part.

Multi-material vessels

Build multi-material constructs, a distinct material for each region.

Droplet deposition

Combine deposition modalities with ease, from single droplets to continuous extrusion.

Preset tissue designs

Begin with a preset design and adjust it, not a blank canvas.

Cleaner toolpaths

BioSlicer optimizes the path architecture to lower the risk of print flaws and wasted material.

Parametric architecture

Shells, infills, channel networks, and heterogeneous zones are parametric objects. Specify gyroid, honeycomb, or lattice infills, pore sizes, and gradients directly.

Layer-by-layer preview

See exactly what the printer will do, one layer at a time, before material meets the plate.

Edit without redoing

Right-click any feature to assign an extruder, set its own speed and target diameter, split it, curve it, or convert it to droplets. No round trip through a CAD expert.

Vascular networks, branched parametrically

Right-click a node and branch from it. Set the count, the length and the angular spread, and the network resolves with the rest of the construct.

Dialog reading Add radial branches from node 4, with fields for branch count, length in millimetres, and angular spread

Branch from a node

Two branches, five millimetres, sixty degrees apart. Parameters, not hand-drawn geometry.

Grown into a network

Repeat it and the network builds up, every node still editable and still parametric.

Patterns assigned layer by layer

A construct does not have to use one infill throughout. Assign a pattern per layer, then repeat the sequence up the stack.

The Layer Pattern dialog: five layers, each assigned a named pattern, with the selected layer set to linear at 180 degrees

Five layers, three patterns between them, each with its own angle, width and line count.

The same model, printed with light

Architecture in BioSlicer is parametric, and never locked into a mesh. So one model resolves into a layer-image stack for digital light processing — slice pitch, image resolution, per-layer exposure — and into an extruded scaffold, layer for layer, from the same source.

Layer four is layer four either way. Nothing is re-authored to change modality: you do not rebuild the construct for a different machine, and you do not leave for a CAD package and come back. See every output the model produces →

One model, any biofabricator

BioSlicer works in paths and exposure regions directly, with architecture specified parametrically, the way you actually think about it. Because the design is never locked into a mesh, one canonical model drives any biofabrication technology, so a construct moves cleanly between the platforms and tools you already run.

Light-based

DLP layer stack

A layer-image stack for digital light processing, generated directly from the parametric model, with slice pitch, image resolution and per-layer exposure. How it works →

Extrusion

G-code toolpath

Cell-friendly extrusion toolpaths with adaptive paths and material-aware capacity.

Interoperable

Standard formats

Standard exchange exports, so a construct moves freely between biofabrication modalities and the tools you already use. Hardware agnostic by design. Nothing you run today is left behind.
