Dacta was an original LEGO theme from 1960 to 2003 that deals with all things that can be used with educational facilities, such as DUPLO and TECHNIC. Dacta was later replaced by the LEGO Education theme. Sets in the Dacta product line were exclusively developed for usage in younger aged schools so the sets typically contain a large amount of pieces for playing and learning in groups. The sets were designed to contain a higher number of bricks and elements at a lower cost.
1963 LEGO Sets
1963 was pivotal for material and design innovation. LEGO completed its transition from cellulose acetate to acrylonitrile butadiene styrene (ABS), improving color stability, durability, and clutch power. The company also launched Modulex—a smaller, precision-scaled building system for architects—produced by the new subsidiary Modulex A/S. Modulex elements were based on a 5mm grid and designed for 1:20 scale modeling, expanding LEGO’s presence into professional design and planning.
