How safe are 3D printing resins?
Extrusion of materials such as Fused Deposition Modeling (FDM) is the most popular polymer 3D printing technology, and resin-based technologies such as stereolithography (SLA) were previously confined to dental laboratories, engineering departments and manufacturing...
Main factors of CNC machining quotation:
1.Material (such as ABS material and PMMA material, plastic material and aluminum alloy price is completely different);
2.Product sizes (the big will be more expensive than the small, the main material cost and processing time);
3.The complexity, including...
In order to make some transparent prototypes, we need to use some transparent materials. The common transparent material PMMA is a relatively brittle and toughness is very poor. Its resistance to impact is very poor. Is there one material both can achieve transparent effect and not as brittle as glass?...
With the processing development, new characteristics of medical instrument housing occurs as below
1.Under the traditional process, the work-piece is composed of several parts. Now, one cut + bending is done. Reached the purpose of reducing the working procedure, shortening the construction period...
When we make some CNC machining parts for prototyping purposes, usually below plastic material will be chosen,
1. For common prototypes, generally choose ABS material, this material is easy to process and after processing is more beautiful.
2. High temperature resistant prototypes, optional...
To efficiently make high quality prototypes with competitive prices, we need pay close attention to 10 Don’t to avoid any quality defects in prototype build.
1.The production process and drawings of the prototyping should not be wrong.
2.(ABS material) when gluing, pay attention to the amount of...
The thermal expansion coefficient of aluminum alloy parts is large, and it is easy to deform during thin-wall machining. When free forging blanks are used, the machining allowance is large, and the deformation problem is very visible.
What measures should be adopted when CNC processing aluminum alloy...
Slow feeding wire-cut machine is mainly used for processing high-precision parts. The work-piece surface roughness, roundness error, linear error and size error from slow wire cutting is much better than fast wire cutting. We need pay more attention to processing accuracy and surface quality...
Metal baking paint characteristics:
Metal baking paint is suitable for coating the inner and outer surface of metal work piece. It can replace all kinds of solvent-based baking coatings. Metal baking paint is used for decoration and protection of metal surface, especially for metal aluminum, alloy,...
Generally the fixture is powered by pneumatic or electric or both.
These 2 powers have their own advantages and disadvantages.
The pneumatic power has low efficiency, poor stability and large noise, which is suitable for some common products with low quality requirements. The electric motor running...
