These materials take longer to fully heat up and increasing the temperature could burn the surface before melting the inside. Therefore, longer exposure periods tend to give better results. ",

The more homogeneous the material is (one type of plastic from the same source) the better the bend. If the plate has multiple sources of HDPE flakes, delamination can occur and affect the result. \n\nThe thickness of the material will also affect how much can we bend the plates. Thicker plates may not bend much without mayor deformations. Also, for thicker plates we may consider to reduce the temperature and increase the exposure timing in order to avoid the surface to degrade.\n\nHave fun bending and exploring new possibilities! :)"
