It is important to note the main benefits of additive manufacturing with 3D printing to the building construction sector, and these benefits are [3,4]:
• Shorter building time [5];
• Mass customization and CO2 footprint reduction [6];
• Use of the right amount of material;
• Generation of complex shape design at controlled costs;
• Reduction of arduous human labour;
• Increased creativity for architects;
• Optimization of acoustic or thermal properties of the building [7].
In addition, in the last years the national and international economic reality has implied a high number of restrictions in the building sector, due to the financial situation and the reduction of the investment observed in the companies associated to the construction sector.
This will avoid complex formworks as well as a reduction in costs and manufacturing time.
The advantages of this technology are clear, namely, the high efficiency, and the reduction of waste and accidents.

Abstract
Biomicrofluidic silhouettes brought about scientific challenges merited to be investigated through explicit florescence observation, implicit physical-chemical analysis and intermediate conductive level manipulation.
This experimental observations can be logically explained: for the increase of Qc, the central viscous force became stronger, which took effects to give more time for the droplet formation, permitting to enlarge droplet size; however, the augmentation of Ql led to enforce the lateral shear stress on the central flow, allowing for the reduction of droplet sizes.

The noise in the data could lead to the over-fitting or under-fitting problem.
The obtained model will have a poor level of performance when applied to a new data point.
Deng Julong [6], is a novel mathematical approach, particularly designed for handling situations in which only limited data are available.
The fields covered by grey theory include systems analysis, data processing, modeling, prediction, decision making and control.
Since the grey model can characterize such an unknown system and can make predictions based on a few data, it has been effectively applied in many fields such as agricultural, socioeconomic and environmental evaluations where limited samples are required. so, Grey system theory utilizes accumulated generating data instead of original data to build evolution model, which makes raw data stochastic weak, or reduces noise influence in a certain extent, therefore, intrinsic regularity of data can be searched easily, and model can be built with relatively little data [8].

An HP 4145B semiconductor parameter analyzer was used to capture low current forward-bias data,
using a 2-probe configuration.
For the JBS rectifiers with the lowest leakage current, the reverse leakage current above 9 kV shows a slight reduction trend as the temperature increases, as shown in Fig.2.
Given the JBS structure, it is not surprising that the reverse-bias stability is comparable to the stability of 10kV PiN diodes (for which we have thousands of device-hours of test data).

As a reference, three sets of data crank length were taken in the text to simulate, and the simulation results were analyzed.
From the above simulation results of these three groups of crank, we can know the blade shearing stage trajectory into a trend of gradual convergence with the reduction of the crank length.
In these three sets of data, when the crank length is 135 (82.5) mm, the overlap of the blade is best, the shear quality is the best one.
