A critical part of any FFF/FDM-based 3D printer is its hotend. Deltaprintr will soon be releasing an all-new "Mini Hotend" which will provide some big benefits in a size up to 50% smaller than available hotends. Once available, the hotend will be priced around $20-30 and will be mounted using two screws--making it usable on virtually any FFF/FDM 3D printer. The Mini Hotend will feature a powerful tiny fan in it, allowing for the printing of materials that require high extrusion temperatures--it can reach up to 700°C (1292°F).
