Some properties of the photosensitive resin were investigated.
SLA part accuracy is a direct result of the resin properties, and a low volumetric shrinkage resin that is cured possesses a high accuracy for its fabricated part.
It has now been found that the photosensitive resins of epoxy-acrylate hybrid systems can be used for SL process, and the photosensitive resins are distinguished by a very low viscosity, a very low shrinkage, a very low curl factor and good mechanical properties in the green state and after full curing.
While glass transition happens to polymers, their physical properties will make abrupt changes, especially mechanical property, their tensile modulus will change the first or second power of ten so as to make polymers turn from stiff solid to soft elasticity, which totally changes the applied properties of polymers.
The experimental results showed that the photosensitive resin possesses good properties.

That have be the key factors to promote the application of oil film bearing about how to improve the load bearing capacity, to run at its best, and to extend the service life.
We analysis the load bearing capacity factors and optimized the parameters to improve the load bearing capacity and running at better performance.
The load capacity was decided by the number of parameters and factors.
It has high mechanical properties, processing performance, and wear resistance, corrosion.
Structural characteristics are the geometry of the bearing oil film thickness and other running properties of features.

These properties may cause large residual stresses during manufacturing processes due
to the mismatch of thermal properties of electronic components that can influence the reliability of
solder joints in electronic packages.

Based on the reviewed literature, a great deal of efforts has been channelled towards the analysis of the correlation between soil resistivity and some factors affecting it.
The observed variation in ρs values at the six test sites gave an indication of heterogeneity in subsurface materials which was as a result of varying soil characteristics accounted for by different D values and MC along with other geophysical properties.
While MC, ST and D factors exhibited significant variation for different values of ρs measured, T was relatively consistent.
The ρs data generated by this study could serve as database for further investigations on ρs in FUNAAB and other environments with similar geophysical properties as well as a guide for grounding system design and installation.

The observed properties are the tensile properties of newly created material, namely yield stress, stress at break.
Such retroactive implementation is subject to the investigation of properties of newly created materials and the testing whether desired properties fall within tolerance bands selected for the product concerned.[1][2] Material Used Two materials were used for the tests: Starex HF-0660I and Senosan® 3000X.
As it is clear from measured values the added secondary material has no serious affect on tensile properties only to a certain percentage extent.
When injecting, plastics degrades under heat and gradually changes its properties.
