eSUN plans to expand its flexible 3D-printing materials with a new series of 2.85mm TPU filaments. The announcement follows Bambu Lab\u2019s unveiling of its H3C multi-toolhead printer, which includes a toolhead designed for 2.85mm TPU-75A and can switch materials in six seconds.<\/p>\n
Although 1.75mm filament is common in desktop 3D printing, 2.85mm filament remains relevant for professional and industrial machines. Its larger cross-section can resist bending more effectively under comparable conditions, helping reduce feeding problems when printing soft TPU grades such as 70A, 75A and 80A.<\/p>\n
The upcoming eSUN range will include four hardness options: 70A, 75A, 80A and 85A. The company says it is working to balance flexibility and mechanical performance, improve melt flow for consistent extrusion, and maintain tight control over filament diameter to support reliable feeding.<\/p>\n
TPU\u2019s elasticity and durability make it useful in applications including shoe midsoles, bicycle saddles, protective gear, robotics grippers, industrial seals, orthotic insoles and rehabilitation devices.<\/p>\n
As 3D-printing equipment and material requirements continue to evolve, eSUN says the new series is intended to give professional and industrial users more options for flexible printing. The filaments are expected to arrive soon.<\/p>\n","protected":false},"excerpt":{"rendered":"
