Engineering & Industrial Models
3D printed scale models of highways, rig equipment, ships, industrial plants and engines, built for engineers, clients and classrooms.
Engineering models explain what drawings cannot: how traffic moves through an interchange, how a drum is driven on a rig skid, or how material flows through a plant. These are real jobs from the PrototypeBD workshop in Dhaka, some designed in-house and some printed from the client's own design.
Each model is FDM 3D printed in parts and assembled by hand. Painting, LED lighting and assembly on a display base are available on request. Upload a file for a quote, or start from photos and drawings with our CAD design service.
