Sparsely populated in relation to its area, the Democratic Republic of the Congo is home to a vast potential of natural resources and mineral wealth. Despite this, the economy has declined drastically since the mid-1980s. At the time of its independence in 1960, the Democratic Republic of the Congo was the second most industrialized country in Africa after South Africa.
Because Polycarbonate is a thermoplastic material, certain 3D printers are able to print with PC using the FDM process. The material is purchased in filament form and the 3D printer heats and deposits the filament into the desired 3D shape. PC for 3D printing is usually limited to a white color.

Over the years, multilateral trade negotiations have helped to substantially reduce tariff rates. Non-tariff measures (NTMs) cover sanitary and phyto-sanitary standards (SPS), technical barriers to trade (TBT), import and export licensing, export restrictions, customs surcharges, anti-dumping and safeguard measures, among others.
Silicon Carbide (SiC) and Carbon filled PLA Composite filaments made for use with Fused Deposition Modeling (FDM) were tested for their shape memory properties. Paper shows the relationship between the thermal and electrical conductivities of the filament and its shape recovery performance.
