The ability to print with multiple materials is very useful, as well being able of printing parts in different colors makes it easier when designing products that have many components such us an engine or car bodywork (we are working currently developing 3D printed prototypes).The software used could be more intuitively organized so we would like better navigation options between layers; this will make our work faster since sometimes there's too much information displayed simultaneously which causes confusion among users who don't know how they should interact properly within each layer/sub-layer structure available from stratify3d application itself.- There isn´t any direct communication option through email if something goes wrong during production process - This has happened before but I think now its solved because after some time ago was introduced online chat feature where one user sends messages directly to other without having them open their applications again everytime needed-.
