Often it has been found a mixture of manufacturing methods and materials is required. 3D printing is more suited for complex shapes as 3D printing allows internal and external shapes to be made in one manufacturing step, with much shorter set up times, however materials are limited to the 3D printing machine type, and the surface finish is rougher compared to CNC machining.
Wood was not used as the materials produces dust particles that for the machining of such large surface with the required surface finish would have contravened aspects of the mandatory Australian health and safety regulations.
Case (iii): Manufacture using a combination of 3D printing and CNC machining This is another example where shape or configuration dictated the choice of materials and machining methods.

Introduction A crisis of confidence on the entire exterior thermal insulation industry has formed by the constant occurrence fire of the building's exterior wall thermal insulation materials and decoration materials.
At present, more than 80 percent of the building thermal insulation materials are organic combustible materials, such as EPS, XPS, PU and others.
Choice of Materials The choice of materials is the key to develop the building material which has thermal insulation and fireproofing double function.

Amongst which most of the researches were on the ESC electrode materials conducting polymers (using as the ESC electrode materials) have attracted much attention for their excellent specific capacitance, high conductive characteristics and low cost [3].
In order to overcome the disadvantage, carbon materials were used as electrode substrate materials.
Fig. 4c is the discharge curves of the ESC with these two electrode materials.

With the surface materials of cold region buildings as the research object in this paper, a study on the changes in the color of surface materials in the cases of discoloration, fading and yellowing is made.
The causes of discoloration, fading and stains vary with materials.
The building materials in this area show different color attenuation from those in temperate regions.
Therefore, it is necessary to perform investigation into building materials and forecast color attenuation, based on which proper materials and methods can be selected. 2 Discoloration and Fading The use of plain colored materials and coatings mainly for protection more or less allows some change in appearance (color, luster, texture) [2].

Explosion-protection performance test After fill materials in the container, the lower the pressure we get the better of the explosion-protection material.
Fill the materials into the explosion box.
Fig 6.The curve when not filled with materials Fig 7.
We can know from the fig that the maximum pressure of the LPG explosion when filled with materials is about 50KPa far lower than not filled the materials.

Taking the surrounding rock of deep-buried at the Jinping II Hydropower Station as the engineering background,the research of similar material and dosage in blasting model test are carried out,based on the scaling method of Froude,the specific parameters of the model materials is determined;through indoor test,different ratio of model material standard specimen was carried out by mechanical test,the mix of similar material is got to simulated the actual rock;base on the theory of explosive stress wave,the research of the similar quantity is carried out.The results shows:froude can be applied to the theoretical calculation of the similar material in the experiments;the acoustic velocity and the strength of the model materials decreased with the increase of water paste ratio;using gypsum,water,sodium phosphate polymer(1-0.62:0.55%) applied to deep marble similar material in laboratory model test;corresponds to the actual blasting engineering 500 kg, 800 kg of similar explosive dosage for
