“…The greatest difference among these techniquesof them [27,32] selectively catalyses materials within a layer of pre-deposited substrate, while the remaining ones Table 6 Comparison of the contents of the main oxides of JSC-1A, DNA, and an average of lunar soil samples from Apollo missions [20]. In particular, the Freeform Construction machine is in principle similar to Fused Deposition Modelling (FDM) additive manufacturing systems [35]. This system is designed to extrude and deposit material at multiple layer resolutions within the same build, above and below 6 mm and its development is presently focusing on creating complex panels (i.e., 'building blocks'), rather than entire buildings.…”

“…Since the candidates are defined by user, there is a possibility that good orientations are overlooked or missed. Masood et al [12,13] analyzed the volume difference between theoretical model and laminated product, the direction in which the difference is minimal considered as the best overall deposition orientation. They looked into the volume deviation models of several fundamental primitives, choose the best direction which minimizes the overall volume deviation from predefined candidates.…”

Rapid prototyping fabricates physical prototypes from three-dimensional designing models using the additive process with layers. Aims at reducing the inevitable volumetric error induced in phrase of model slicing which impacts the shape accuracy of fabricated entity, a fast determining scheme of optimal slicing orientation for least volumetric error is proposed. The work analyses the staircase effect between two consecutive layers, then infers a direct computing formula of volume deviation of a whole model. Introduces the term of area weighted normal to express the significant effect of facet area on volumetric error and converts the optimal orientation determining problem to the least absolute deviation linear regression issue. Employs prominent components analysis on weighted normal set to obtain an approximate orientation efficiently, then optimizes the solution through few searchings in neighboring orientation space. The validity and efficiency of the algorithm are evaluated on several examples. Results demonstrate that proposed algorithm consumes less than 32 % of computation load and adaptively obtains the optimal slicing orientation.

“…The orientation with the highest score is selected as the desirable build-up direction. Masood and Rattanawong [9] developed an algorithm to calculate the amount of volumetric error caused by slicing a CAD model. Volumetric errors are calculated for different orientations by rotating about user-specified axes.…”

Several important factors must be taken into consideration in order to maximize the efficiency of rapid prototyping (RP) processes. The ability to select the optimal orientation of the build direction is one of the most critical factors in using RP processes, since it affects part quality, build time, and part cost. This study aims to determine the optimal build-up direction when a part is built with the variable layer thickness for different RP systems. The average weighted surface roughness (AWSR) that is generated from the stair stepping effect, the build time, and the part cost using the variable layer thickness are all considered in the process. Using the multi-attribute decision-making method, the best orientation is determined among the orientation candidates chosen from the convex hull of a model. The validity of the algorithm is illustrated by an example. The algorithm can help RP users select the best build-up direction of the part and create an efficient process planning.
