![]() In terms of price, a filament spool is relatively cheap compared to other materials and can be purchased for between 17 and 35 dollars. When dealing with liquids of this type, you should protect your eyes, respiratory tract and hands to avoid irritation. Therefore, you should only use it as a support structure for materials such as ABS, because certain other materials can be sensitive to the chemical limonic acid, and as a result, the component might be damaged.īefore removing support structures with chemicals, it is recommended to first remove large parts by hand for cost reasons, as one liter of chemical costs approximately 30 euros. Unlike PVA or BVOH support structures, HIPS needs to be removed with chemicals. In addition, it is a safe food-contact material.Īfter the printing process, you should wait until the printed part has cooled down completely before starting to remove the supporting structures. It also has a smooth and scratch-resistant surface, it is heat resistant, and its white translucent color simplifies coloring. It is typically used in the area of ABS printing as support structure, and the temporary stability of the HIPS form plays a central role here. As already mentioned, the material is particularly characterized by its comparatively high solubility in relation to certain chemicals, which allows for relatively smooth separation when used as a support structure. HIPS has similar properties to ABS, but is harder and more impact resistant. This article reviews the properties of HIPS as a filament and the advantages it offers as a support structure. After the printing process is completed, these structures are removed, which is easier with materials such as HIPS, which have high solubility. Backing materials, or support structures, are used to print parts that have an angle of more than 45 degrees to prevent them from slipping or breaking during the printing process. ![]() However, in the case of HIPS, the solubility is a great advantage because the material is mainly used in filament form as a support material in FDM 3D printing. Many popular materials in 3D printing are particularly characterized by their resistance to chemical solvents. HIPS (High Impact Polystyrene) is a thermoplastic polymer based on a mixture of polystyrene and polybutadiene rubber.
