The Additive Advantage

3D printing is increasingly being used to print finished products.
3DPrintUk can print products at a price as low as 20p per unit. It is not costly anymore.

General Electric - Auburn, Alabama Plant - Nozzle Production by 3D Printing


First Production Application of 3D Printing by GE

When it opens in 2015, the General Electric Auburn plant will be producing fuel nozzles for the next-generation LEAP jet engine using 3D Printing.


Each engine will have nearly twenty 3D-printed fuel nozzles.The nozzles are five times more durable than the previous model. 3D printing allowed engineers to design them as one part rather than 20 individual parts, reducing the number of brazes and welds that would have been necessary using traditional methods.

Texas Instruments
Why Hall effect sensors for magnetic position sensing?

TI's magnetic Hall effect sensors are known for robust durability and dependable operation for any position sensing application. Whether simply detecting the closing of a lid or perfroming complext motor commutation and precise position measurment, Hall effect sensors will reliably and accurately sense the position position in your system.

Industrial applications for magnetic sensors
Key industrial applications

Cordless handheld garden tools & cordless power tools - Hall effect sensors provide position measurment in motors, speed selectors and triggers to carry out proper functions.
E-meters - Hall effect sensors offer solutions for magnetic tamper and case tamper detection.
Door & window sensors: Hall effect sensors can be used to detect window and door tampering for home security.
Automotive applications for magnetic sensors
Key automotive applications

Electric power steering - Monitor the position of the shifter, motor, steering wheel angle and torque with Hall effect sensors.
Body motors - Hall effect sensors enable motor commutation in various modules throughout the vehicle.
Engine fan & pump - Monitor the status of engine fans and various pumps wihin the vehicle using Hall effect sensors.

ABSTRACT


Overcoming some of their process limitations of additive manufacturing technologies is  important now. Two such limitations of present layer-based fabrication are slow speed and geometric constraints.

Holography is now in use as a means for storage and retrieval of 3D geometrical information. This research  explores the use of holographically-shaped light fields for producing three-dimensional structures in a “volume at once” approach. Using spatial light modulator (SLM) technology, phase-controlled light fields are projected into photopolymer resin to cure a desired geometry. By overlapping multiple sub-regions of a single light field within the target volume, the successful fabrication of non-periodic complex 3D geometries is demonstrated by single exposures on timescales of seconds in this research project.

The research also created  a complete prototype platform that makes this approach possible, comprising a suitable hardware configuration along with the computational algorithms necessary to calculate and optimize the required optical fields.

A study of the photopolymerization kinetics is also carried out, to determine the boundaries of usable process parameters such as resin absorbance and available light intensity.

The results indicate that low-absorbing resins containing ~0.1% photoinitiator, illuminated at modest powers (~10-100 mW) may be used to produce full 3D structures from 1-10 second exposures, with volume build rates exceeding 100 cm3/hr. There is no need for a substrate or support material that are necessary in the present layer by layer 3D printing.

SMED to  SM3D


The layer by layer 3D Printing will be substituted by a 3D image created in the resin by holography and within minutes you have the shape you want.

The SMED now becomes SM3D.

You will be able use items made using this technology.

If you are an engineer, you have a new technology to learn and develop.

If you are scientist, you have research opportunities.

Feel proud as the science underlying might have been initially discovered during 1750’s.  What you think today and discover benefits the universe some day or other.
