Description

Technical Field

[0001] This utility model relates to the field of urban prototyping technology, specifically to a rapid prototyping support device for urban prototyping. Background Technology

[0002] Urban-scale rapid prototyping support equipment is a device used to assist in urban-scale rapid prototyping. Urban-scale rapid prototyping support equipment is usually based on the principle of layered manufacturing and combined with urban-scale rapid prototyping technology. During the model building process, according to the pre-designed model data, the equipment will automatically generate support structures at the required locations. These support structures are used to support the suspended parts during the model forming process, preventing the model from deforming or collapsing before it is fully cured or formed, and ensuring that the model can be accurately built layer by layer according to the design shape until the entire urban-scale model is completed.

[0003] Urban scale models typically have complex shapes and structures, requiring the design of reasonable support structures to ensure the stability of the model. However, for some complex models, the design of support structures can be very difficult, requiring a lot of time and effort to adjust and optimize. If the support structure is not designed properly, it may cause problems such as deformation and collapse of the model during the molding process. Utility Model Content
