TPT BioCAD

Open-source CAD and slicing software for bioprinting and food printing with integrated rheology solver.

Overview

TPT BioCAD is a unified Computer-Aided Design (CAD) and slicing software platform specifically engineered for bioprinting and food printing. Unlike traditional slicers optimized for thermoplastic FDM/FFF printing, TPT BioCAD natively integrates a computational fluid dynamics (CFD) and rheology solver.

Features

• Rheological Models: Carreau-Yasuda, Herschel-Bulkley, Bingham plastic
• STL Import/Export: Standard mesh format support
• 3-Axis Slicing: Basic slicer for standard thermoplastics
• G-code Generation: Standard and extended M300-M303 commands
• Material Database: Pre-characterized bio-inks and food materials
