The lattice constant, or lattice parameter, refers to the physical dimension of unit cells in a crystal lattice. Lattices in three dimensions generally have three lattice constants, referred to as a, b, and c. However, in the special case of cubic crystal structures, all of the constants are equal and are referred to as a.
 
The model from the picture was printed with a Artillery Sidewinder X1, 0.2mm layer height, 0.4mm nozzle, 120mm/s speed, heated bedplate and a cooling fan. The material used in this model is 1.75mm high quality PLA+.
The PLA+ was extracted and purified from corn grain; High rigidity, good glossiness and transparency; Suitable for printing larger models; Toughness is 10 times more than the normal PLA on the market. No wiredrawing problems, the surface of the printouts will be smoother and moredelicate; No cracking problem.
