Opis:
The paper presents the results of experimental study – part of research of additive technology using thermoplastics as a build material, namely Fused Deposition Modelling (FDM). Aim of the study was to identify the relation between basic parameter of the FDM process – model orientation during manufacturing – and a dimensional accuracy and repeatability of obtained products. A set of samples was prepared – they were manufactured with variable process parameters and they were measured using 3D scanner. Significant differences in accuracy of products of the same geometry, but manufactured with different set of process parameters were observed.

Opis:
Fused Deposition Modelling technology allows to produce elements of very complex shapes without any additional tooling, which is why it has a broad range of industrial applications. Possibility of manufacturing parts with controlled degree of internal filling allows to shorten the manufacturing time and reduce volume of used material. The paper presents influence of layer filling type on part capability of carrying loads and economical coefficients of the manufacturing process. A problem of mechanical properties is important especially in case of elements used as functional prototypes. The paper presents methodology and results of experimental strength tests of samples with various types of internal filling. As a build material for test samples, ABS material was used. Composite samples were also used the ABS matrix produced by Fused Deposition Modelling was filled with chemically hardening polyurethane resin in a process developed by authors. The samples were subjected to destructive testing and their strength properties were compared.

Opis:
The paper presents results of experiments aimed at determination of range of critical orientation for parts manufactured additively using the Fused Deposition Modelling method, out of ABS material. Numerous previous observations of plastic parts manufactured additively using the FDM process allowed concluding, that change of values of the manufacturing orientation (i.e. direction of layer slicing plane) has large influence on the macrostructure of obtained parts, thus affecting their strength and behaviour under load – the material behaves either as a thermoplastic with a yield point or as a brittle material with no yield point. The paper presents methodology and results of experiments aimed at determination of a certain value or value range, at which transition between the two behaviours occurs. The experiments consisted of tensile tests performed on samples manufactured additively in a pre-selected range of orientations. The obtained results – a value range valid for the selected type of load and sample shape – will be useful in future to help select an optimal orientation of part for a defined task.
