Pro HT




BigRep's Pro HT is a general-use bio performance material for open-environment 3D printing.

With a softening resistance up to 115 °C, it has a significant increase in temperature resistance compared to the average PLA; making it ideal for practical, end-use applications.

With increased temperature resistance, minimal warping and shrinking, Pro HT is an ideal PLA alternative and the choice material for wearables or any general purpose product that may face higher than average temperatures.

Easy printing and support removal make finishing Pro HT parts simple and excel in low-volume additive manufacturing, even for end use. The material is scale dynamic, allowing designs to maintain their quality between large-format and desktop 3D printers.

As a material derived from organic compounds, Pro HT is biodegradable under the correct conditions. CO2 neutral and environmentally friendly, it has a much lower ecological impact than other plastics derived from fossil fuels.

Pro HT is FDA compliant for food safety and meets all requirements of EU Directives on food contact.
