HP metal jet the quality technology

Posted on Updated on

According to HP,” metal jet the quality parts, design, are accessible. The product is compatible with geometrically complex parts. With HP voxel-level 3D printing accuracy. This is an industrial production-grade 3D printer.”

HP Metal Jet is a technology developed by HP for the production of metal parts using 3D printing. It is a type of binder jetting technology that involves depositing a binder onto a layer of metal powder, layer by layer, until the desired object is built. The object is then sintered in a furnace to fuse the metal particles together and create a solid metal part.

HP Metal Jet has several advantages over traditional metal manufacturing methods, such as casting and machining. It allows for creation of complex geometries that are difficult or impossible to produce using traditional methods and can reduce the amount of waste material generated during production. It is also faster and more cost-effective for small to medium-scale production runs.

In terms of quality, HP Metal Jet can produce parts with high accuracy and resolution, with a surface finish comparable to that of traditional manufacturing methods. The technology also offers a wide range of compatible metals, including steel, titanium, and copper, allowing for various applications across the automotive, aerospace, and healthcare industries.

However, like any manufacturing process, the quality of the final product depends on several factors, including the quality of the initial design, the properties of the metal powder used, and the control of the printing and sintering processes. HP Metal Jet technology is still relatively new, and further research and development will likely lead to improvements in the quality and performance of the technology.

 

What kind of objects or designs do you think would be best suited for HP metal jet printing, and why?

3D printed human tissues using DNA

Aside Posted on Updated on

As mentioned by Professor Gartner of UCSF, ¨have developed a technique to build tiny models of human tissue called organoids. The technique uses DNA to guide the assembly of cells into organoids. This technique is called DNA Programmed Assembly of Cells (DPAC). The research team created several organoid arrays mimicking human tissues such as mammary glands. The research was published in the journal Nature Methods on Aug. 31, 2015.

This technique incubates cells with snippets of single strands of DNA  The DNA attaches to the cell’s outer membrane. The incubated cell attaches to other cells that are incubated with matching DNA strands. In other words, the cell doesn’t attach with other incubated cells if their DNA sequence does not match. A cell can be incubated with more than one type of DNA cell. This allows the cell to attach to different types of cells. This technique is similar to playing with Legos. A lego piece can attach to other lego pieces if they have matching sides. This simple trick allows lego pieces to be combined to build a very large variety of toys.  Similarly, DPAC uses DNA strands attached to cells to create different types of organoids.¨
