Industry Standards
Existing Open Source Designs
Minimum Viable Product
- Modular
- Precise
- Fast
- Ultra Low Layer Height
Basic Design
- A cube/rectangular prism is gradually filled with powder (precise layer by precise layer)
- In between each layer being filled, a laser (moved either on a gantry or woved with optics) traces a 2D sliced image on each layer
- This gradually buils up the object
- The powder not used for the part allows for a built in support structure (unlike sla or fdm machienes)
- Once done the part (and possible a printed part box") are lifted out and powder is brushed+blown+vacuumed away in a device similar to a sandblasting cabinet or laminar flow hood
