However, the chemical composition of emitted particles has been less extensively investigated. In this study, we therefore focused on the chemical composition of particles emitted from 3D printing. The measurements were conducted in a 1 m³ emission test chamber. Emitted particles were sampled by a 13-stage low-pressure cascade impactor onto aluminum foils and then analyzed by TD-GC/MS to identify their organic compounds. Nine commercial filaments made from basic polymers such as Acrylonitrile Butadiene Styrene (ABS), Acrylonitrile Styrene Acrylate (ASA), Polycarbonate (PC), Poly(methyl methacrylate) (PMMA), Nylon, High Performance Polystyrene (HIPS) and a copper-filled Polylactide (PLA) were investigated. The results show that the organic components of the particles are primarily plastic additives such as plasticizer, antioxidant agents, lubricants, UV-absorbers and UV-stabilizers from the filaments.

A1 - Kalus, Sabine A1 - Horn, Wolfgang T1 - Determination of formic and acetic acids in air N2 - Formic and acetic acids are often responsible for damage of cultural objects, e. g. glass and metal corrosion or changing and fading of colours. Museums all around the world are equipped with different show cases. Display cases should protect cultural objects from dust as well as from mechanical damage. Several construction materials which are used for display cases, including wood, glue and coatings, are possible sources of very volatile organic compounds (VVOCs), volatile organic compounds (VOCs) and semi volatile organic compounds (SVOCs). These construction products can emit formic and acetic acids into the indoor or display case air. Modern display cases with small air change rates can cause higher concentrations of formic and acetic acids if any source is installed in the display case (Salthammer and Uhde, 2009). To minimize the risk of damage emissions from building products must be quantified. There is a need for a method for identification and quantification of acetic and formic acid. Some possibilities for the identification of acetic acid exist. The quantification of acetic acid for example after sampling on TENAX® or CARBOTRAP and thermal desorption-GC in accordance with ISO 16000-6 and ISO 16017-1 results in very low recovery rates. A new method should be stabile, robust, reproducible and comparable, with an easy local sampling and determination in laboratories. Miniaturised emission test chambers and model display cases were used to study the recovery rates.

The amounts of volatile organic compounds (VOC) which emit from products in emission test Chambers are used to evaluate these products. Typically labelling procedures for construction products are based on emission test chamber measurements. This performance should be verified. Possibly this can be performed due to testing of one material at different laboratories within a round robin test. Therefore it is necessary that a reference material exists which can be used for such round robin tests or as part of the quality management System to ensure comparable results. The different Statistical evaluation possibilities of a round robin test with a constant reference material for VOCs (volatile organic compounds) in emission test Chambers are the main focus of the presented paper.
