Purchasing Considerations
- Resolution (in X, Y & Z)
- Minimum feature size
- Build envelope size
- Suitability of the material for intended purpose
- COST (resin cost, support material)
- Creep resistance
- Chemical properties
- Ability to be coated, plated
- Variety of materials available for the particular machine
- Build speed
- Support material removal
- Cost of supporting materials
- Solvents, cleaning material
- Purge material
- Other consumables, trays, etc.
- Cost of services agreement
- File formats (compatibility with existing software)
- Idle time (some machines must be used consistently)
- Regulatory compliance
- Special requirements
- Additional computers and hardware
- Ventilation
- Power consumption
- Uninterrupted power supply
- ALWAYS – talk to an owner of the machine you plan to buy
- ALWAYS – get a model that was printed on the machine you will buy
