1. Functionality and Capabilities:
- Machine Type: FabLabs often opt for CNC routers due to their versatility. They can cut, carve, and mill various materials like wood, plastic, and aluminum. For specific needs, 3D printers or laser cutters might be better choices.
- Work Area Size: Consider the project sizes you typically handle. Common options include desktop-sized machines for smaller projects or larger machines for furniture-making.
- Material Compatibility: Identify the materials you plan to use the most. Different machines have varying capabilities in terms of material hardness and thickness.
- Tooling Options: Think about the types of cuts and finishes you need. The machine's spindle power, toolchanger, and dust collection system will impact these.
2. Budget and Maintenance:
- Machine Cost: CNC machines can range significantly in price. Set a realistic budget considering not just the upfront cost, but also tooling and ongoing maintenance.
- Maintenance Requirements: Consider the ease of maintenance, access to spare parts, and technical support available. Ideally, the machine should be user-friendly for routine maintenance tasks.
- Space Constraints: Measure your available space and choose a machine that fits comfortably.
- Skill Level of Users: If beginners will be using the machine, prioritize user-friendly interfaces and safety features.
- Community and Support: Look for machines with active online communities or manufacturer support for troubleshooting and knowledge sharing.
- Research Popular FabLab Machines: See what machines other FabLabs use and read reviews or user experiences.
- Start Small and Scale Up: If your budget is limited, consider a smaller, more basic machine and plan to upgrade later based on your needs.
