3D Printing, Inkjet

3d printing

Yeas ago, while sitting around the table with some very talented phd's, technicians and engineers in Cambridge I could see the 3 dimensional technology would have some practical applications. Discussing the subject I became aware that there was already work underway with those with lineages from the likes of Domino sciences and other groundbreaking entities from previous generations. I could see it would be an interest to corporations and even military work both in the field and in the lab and carry with it an innovative approach in building and creating solutions. There are a few different methods including jetting through the nozzles, building layers upon each other as well as a method that builds up layers after the print swath leaves layers of specially formulated ink on top of specially formulated powder's after curing each layer.

3d objects can be printed after software takes a CAD image and slices the files into thin layers (unique slices) with instructions for the printer. There are free open source software packages like MeshLab that do a great job at this as well as other options free and at cost from AutoDesk etc.
At times in development there can be some interesting finds when attempting different prints and images may be re-sliced a few times by talented engineeers in order to get the desired result.

A few companies offer desktop models with user friendly software packages that can be used out of the box for simple object creation by the end user. The cost is becoming more realistic for consumers as progress is made.

It seems there is still allot of wonder as to how to use this technology.

There are 3d scanning devices and companies springing up around the scanning end as well as some handheld wand type scanners created by some of the printer companies that scan an object and process the information to the slicing software. Some of the scanning technology I have seen can be tedious at the moment requiring placing a series of numerous tiny white stickers on an object while a scanner that consists of 2 cameras and a laser at the center captures images as the object is rotated by the user to various points.

Contrary to some of the current beliefs I have seen materials made that have good strength and even some processes that have a high degree of speed.
Some of the 3d technology I have seen is impressive

I have been out of the Inkjet PIJ and TIJ technology field for so long it was quite and interest to see the technology again as I have briefly been back into a few companies for acquirements in the technology before entering back into the aerospace industry. I will be writing some key notes about the technology soon and posting them.

Also see the other interests page to see photos and videos of my surfing and guitar playing. | The purpose and reason of this weblog is to store some information, host my resume info and create a space where I can write and record information that I can refer back to in the form of documentation or instructional video. | Also see the other interests page to see photos and videos of my surfing and guitar playing.

I found that even in teams where I wrote a technical document with screen captures, data and drawings I found that I would need to refer back to my own documentation at times. This help me to complete a task if I had moved on to other day to day tasks and had not worked on my own process for ad extended period of time.

Background for this weblog:
Various places I have worked and tasks I have worked on.


Data:
Is stored in the posts and pages. I am careful to not disclose proprietary information and adhere to any non compete agreements and keep my own records in non accessible formats and locations.

The result of this weblog will hopefully be a useful archive.

This site was created on blogger (blogspot) to show what kind of editing can be done of the framework code. I have designed some websites for businesses with top level domain names (www.yourname.com) using blogger as the host with a simple DNS switch which displays the dot com instead of blogger .blogspot URL. I have been html coding for years and have designed sites in straight html, built sql databases for more robust sites and use also WP allot for the dynamic flexibility in building websites with lots of features and and sql handling.

Vacuum chambers atmosphere manipulation

In producing anti reflective layers, reflective, dialectric, absorbent and other thin films in vapor deposition under atmosphere, a robustly sealed environment is needed to hold low atmospheres as achieved by turbomolecular, diffusion, cryogenic and other pumping systems.

I have experience in the three mentioned above with the amplitude being in the latter two and less in the former.

In the large vacuum chambers I have worked with I typically achieved base pressures as low as 3x10-8 torr.

In ophthalmics for example it was standard to achieve 3x10-7 base pressure before the 1st layer commenced.
The ophthalmic industry machines used a high degree of automation whilst I have worked with chambers that require more involvement.

In some environments a chiller is used in conjunction with poly-boxes or poly-colds while on the other end of the spectrum I have filled my own liquid nitrogen tanks from large supply tanks for use in manually pumping ln2 through a meissner. Some meissners I helped construct and install in experimentation for best or ever changing result requirements.

In high vaccum environments coatings are produced using electron beam guns and ion sources as well as other simpler sources such as jori's.
Beams are shaped and manipulated using basic elements and more complex parts that can vary in laboriousness and complexity.

Ion sources create & manipulate atomic & molecular ions, collisions with atoms, sub atomic particles, atoms, molecules and ions in a high vacuum environment with varying low pressures.
Typically a minimum pressure is needed in order to prevent arcing and for best results.

I was first introduced to vacuum chambers in the ophthalmic industry where I accepted an offer for a Sr. Technician position and later grew into a management position in a fairly long tenure with an innovative organization. This later translated into Aerospace and other industries where I spent a few years in a Sr. Technician role.

Some notes on pumping systems for low atmosphere sealed environments. The brief notes here cover diffusion, cryogenic and turbomolecular. There are a few other ways to achieve low atmosphere than the ones listed here.


Cryogenic


Diffusion

The diff pumps I was around were very large and could sound like a jet taking off if you were in the same room when the chamber was sent on its way to pump down to low atmosphere. It was intuitive to build a separate room behind the chambers in the lab to house the pumping system. Here is a link below to a diff related article

Currently at the time of this writing I work in the Aerospace industry in  a union. I am hoping this is a long career.
I am scaling back on extra contract work to the most interesting projects if any. I received a few contract requests which is good after listing my resume in need of a new direction.

A summary of companies I have worked for can be found below. For the most part I have worked at a few companies with some being parts to a larger picture which is how the list is compiled. For example I worked a few weeks on project that successfully made a parachute with solar absorbent and reflective properties to bring in a satellite. This was part of a long full time position at another companies where I worked on projects with longer timelines.

Building craft capable of reaching other planets

It would be an extraordinary feat to be able to one day travel to a comfortable survivable planet with comparable atmosphere and a suitable environment for living.

Since it is now believed that there are potential habitable planets based on space telescope observations the question would be how to get there. I have thought from time to time of standing on the distant shore of a completely new world, surfing waves of a new ocean or a mountain to look out over distant landscapes.

 One challenge would be how to get there which would require engines capable of speeds faster than anything ever known to man. One of the other requirements would be the architecture itself being able to withstand the solar energy of sun(s) and atmospheric conditions of space. I know how it would be possible to make the architecture and outer shell of such craft with the right elements found here on earth combined with the process in which to apply them.

What I do not know and doubt anyone does is how to obtain speeds capable of reaching distant planets within a workable time-frame. There could be an extremely fast engine combined with an orbit of the earth to project and traject the vessel with great velocity on its path.

I guess there could be a million years or so for people to work on this since eventually the world will be a swirling mass of hot lava before its consumption by a star further along its timeline. That is also assuming that earth and its atmosphere are not trashed by the its cohabitants before that. Selfishly, I have a desire to enjoy the world as much as possible for myself and immediate loved ones in the near future and next 50-60 years lifespan and more for my children and grandchildren. There are requirements for making the world better even in the current and near future with good projects such as one of the proposed ways of cleaning up (and making money in the process) the garbage patches growing where the ocean jetstreams interconnect.
