Flex 80A is a resin material designed for use in Stereolithography 3D printing, abbreviated as SLA. In its raw form, Flex 80A is a liquid material that solidifies (polymerizes) using UV laser technology. Flex 80A is engineered to simulate the properties of thermoplastic TPU (Thermoplastic Polyurethane). However, due to the UV curing process, it exhibits some variations from traditional TPU, lacking meltability and possessing increased brittleness.
Flexibility Flex 80A is characterized by a rubber-like flexibility. The flexibility of the printed part can be tailored by adjusting its geometry. It's important to note that the flexibility cycles of Flex 80A are limited. Components made from Flex 80A cannot endure sustained flexural stress.
Ideal for Water Applications One significant advantage of SLA-printed parts is their high density and water resistance, making them suitable for floating and water flow tests. Additionally, the exceptional surface quality makes Flex 80A parts ideal for wind tunnel applications and fluid dynamics analysis.
Weather Resistance SLA parts, including those made from Flex 80A, are generally not weather- or UV-resistant and are often employed for prototyping purposes. It's recommended to use components made from Flex 80A in environments shielded from outdoor exposure.
Support Material In SLA 3D printing, the support material is identical to the printing material and requires manual removal, which can impose limitations on design freedom compared to other manufacturing methods.
Post-Processing Flex 80A parts can be post-processed to achieve high-quality results. They can be produced with fine details (down to 0.05 mm) and sharp edges. Through post-processing steps like painting or coating, these parts can be adapted for long-term applications.
