Comentário geral sobre o conjunto de dados This dataset covers all relevant input and output flows of the represented gate-to-gate unit process. The inventory is mainly based on industry data for a pilot product scale and, where necessary, complemented by secondary data. The reference flow is one printed part with 75% infill as baseline, and all inputs and outputs are normalized for each machine operation mode. The inventory flows were parametrized for the different operation modes (stand-by, filament loading, table heating, pre-printing, nozzle heating, printing, filament unloading, and filament winder) of the 3D printer.

Representatividade tecnológica
Descrição da tecnologia, incluindo sistema de fundo Current technology for the FDM 3D technology process. The infill percentages were varied to analyse the influence of this parameter on the inventory results. This additive manufacturing process considered the following production modes: - Stand-by: when the printer is not operating, while its electronic panel is on. - Filament loading: it happens when the filament is loaded in the machine (filament made of recycled ABS). - Table heating: the machine spends time, normally 40 minutes, heating the table before a printing process. - Pre-printing: this mode of operation consists of a sequence of steps performed by the printer to ensure that the table is in the right place and the distance between the nozzle and the table is correct. - Nozzle heating: heating the extruder nozzle of the printer. - Printing: the mode of operation in which the parts with different infill % are printed. - Filament unloading: similar to the loading mode, but taking the filament out of the tube.

gd_price_waste 0.5 % This parameter was added by GreenDelta during the implementation of the ecoinvent database in openLCA. It is used by those exchanges which did not have a price specified by ecoinvent for being wastes (i.e. negative reference product), and that were considered that they should have a cost/revenue specified. The prices used for them, equal to the prices of the same product in other processes of the database, are modified by this parameter with value 0.5 (i.e. half the price of the normal product), considering that the reference product of a waste treatment process might have a lower price in reality than the same flow produced by a production process. However, you can modify this value to 0 if you prefer to consider no price for them like ecoinvent, or also 1 if you do not want to distinguish wastes from other products.
gd_price_product 1.0 % This parameter was added by GreenDelta during the implementation of the ecoinvent database in openLCA. It is used by those exchanges which did not have a price specified by ecoinvent and that were considered to be products or co-products of waste treatments (i.e. positive reference product), and that they should have a cost/revenue specified. The prices used for them, equal to the prices of the same product in other processes of the database, are modified by this parameter with value 1. However, you can modify this value to 0 if you prefer to consider no price for them like ecoinvent.
ei_price_product 1.0 % This parameter was added by GreenDelta during the implementation of the ecoinvent database in openLCA. It is used by those exchanges which did not have a price specified by ecoinvent in this specific system model, but yes in at least one of the other two system models. The prices used for them, equal to the prices of the same product and provider in the other system model, are modified by this parameter with value 1. However, you can modify this value to 0 if you prefer to consider no price for them in this system model like ecoinvent.
Heavy_metal_uptake 1.0 % Take the heavy metal emissions into account? Yes = "1", "no" = "0" (If the heavy metals direct emissions are included, put the value to "1". If the heavy metals direct emissions are excluded, put the value to "0".)
