Edit:
Hey so the point of this post is to make sure if I get into a master's of engineering for additive manufacturing (which is how most programs are listed) will it be just as good as a master's of science which I believe only Penn State, university of Miami and Carnegie Mellon have M.S. programs. I have a mentor who says that a master's is a master's but having to write a thesis (which most M.S. programs are requiring) helps you stand out more as a PHD candidate. Thanks for any more info.
Hi! I'm currently looking for opportunities in the additive manufacturing industry, and I could use some advice.
A bit of background information on me - I have a Bachelor's degree in Materials Science and Engineering, and I am currently a materials engineer that specializes in non-destructive inspections with 3 years of experience. While I believe that the field of non-destructive inspections is a great tool for a materials engineer, I have struggled to see myself building a decades-long career out of it. The location of my workplace is also... not great, being in a rural area.
I was always fascinated with additive manufacturing and 3D printers: my senior design project was related to the field of additive manufacturing, I own a hobbyist 3D printer, and I am currently in a rotation at a laboratory partially because I wanted to be more involved in additive manufacturing.
So, where should I begin? I've already started applying for a few places, namely some start-ups, but I'm not sure if I have a good shot of getting my foot in the door. Where should I start looking?
I am super intrigued by additive manufacturing and have been working on 3d printers and rendering for about a year now. I currently have a job in risk analysis and I just don't think this job really ignites a passion in me. I have been studying a few papers on editing gcode and that has really interested me. I will be coming up on one year with my company in January and would like to start looking for a job that is more aligned with my interests which are design and manufacturing. I am curious what I can do / places I can look at to apply for jobs or perhaps even masters programs. Any suggestions appreciated. I have a B.S. in applied physics and a minor in mathematics. I enjoy electronics projects, pc building, car building, motorcycle building, electronic circuits, and many other hands on projects. Currently I work an office job that consists of reading all day. I really cannot complain but I would like a job that I am excited to come to work to for. I would not mind reading/researching all day if it involved AM.
Anyone taken/taking this mod? How is the workload and are the lectures online and/or recorded?
I am trying to do wire arc additive manufacturing of aluminium with fronius tig welding setup.
Problem:
- I tried to deposit five layers one after the other with 3minutes of cooling b/w each layer, but it's not working.
- The depositing layer droops on the previously deposited layer. Different layers can't be differentiated.
Operating parameters:
- Current: 150 amps (AC)
- AC frequency: 100 Hz
- Welding speed: 115 mm/min
- Wire feed: 1.4 m/min
- Tungsten electrode (grey): 3.2mm
- Plate: 6063
- Wire: ER4043
Should I use pulse too?

Hello there!
I'm currently working on a project involving optimising a Wire Arc Additive Manufacturing (WAAM) system which is essentially just a large scale 3D printer with a MIG welder instead of a filament extruder to 3D print metal parts.
We do have MasterCAM, but only one license, so I'm trying to see if Cura could be used to generate GCode instead. The bead height of direct deposit welding is much larger than the layer height of FDM prints, but I'm running into issues whenever I try to print something with a layer height greater than 4.0mm. Is this a hard limit in Cura, or could this be down to something else? I've put a nozzle size of 15mm and compatible material diameter of 20.0mm (not the actual wire we're using, but the bead is about 8mm high and 10mm diameter so I'm trying to make Cura think the machine is capable of high flowrate).
Any ideas on how to increase the layer height above 4mm?
Cheers very much for your help.
I was curious as to what the lowest wire diameter is that can be used in WAAM. Most of the studies in the literature use 1.2 mm wire, while the lowest I've seen is 0.5 mm.
Can we use a wire of say 0.1 mm wire? Are there any process restrictions?
How is it working in the companies like GE Additive, HP (3D Printing), Stratasys, Markforged, et cetera?
What does your day look like? How is the pay? What are the opportunities for a Mechatronics Engineer? What degree did you do before joining such companies?
I'm a BSEE aiming to pursue my Masters in Mechatronics or Robotics. Hence, I just wanted to know what it's like and how is the market and job opportunities. I'm really into 3D Printing and want to learn and help contribute in it's progress as we all know that it's got a lot of potential.
I think that the control aspects are saturated as of now, and it's been perfected. Any or all innovation to be made is in materials aspect so that processes can be fast, products can be stronger and such. Please provide some insight!
Thank You so much! :)
I wanted to open this up by saying I really enjoy this community and I have learned a lot from this forum. I would really appreciate some advice and thoughts on how best to improve myself to land an additive manufacturing engineer role.
For background, I currently work in the manufacturing sector and have a bachelor's and masters in materials engineering. I took the MITxPro additive manufacturing course this summer and am pretty heavily involved in FDM and SLA printing as a hobby. With that, I have a pretty good understanding of CAD, but all self-taught so probably not at the level I would consider professional.
Does anyone have any thoughts on what kind of skills I should be working on or if there are projects to better showcase my skills? I have been studying to take the SME Additive Manufacturing Certification Test as well. Id like to get opinions on what I should focus my efforts on more so that I can be as competitive as possible.
Thank you in advance for any feedback!

3D Printing for Joint
Agile Operations
By Jaren K. Price, Miranda C. La Bash, and Bart Land
The Navy seabase off the coast of Africa is like a floating hive, with personnel moving
about aboard multiple ships and both aircraft and landing craft launching to deliver the
second wave of the assault force to their objectives. Teams of mechanics examine several
Army and Marine Corps vehicles recovered from the beach via landing craft air cushion.
One team triages damage in preparation for repairs required for expedited return of the
vehicles to the field. Another team assesses the more significant damage done to a joint
light tactical vehicle (JLTV) that struck a mine. The mechanics submit requests for repair
parts. Some parts are immediately retrieved from stores located on the seabase, while man-
ufacturing specialists load blueprints from a database for those parts not already on hand.
Soon, three-dimensional (3D) printers hum. Meanwhile, the specialist engineering team
develops a repair solution for the JLTV, and an engineer drafts the 3D design. The new
plans are also transferred to print production. The parts are delivered to the mechanics
who then complete the repairs. Within hours, the vehicles are ready for return to their units.

n the near future, this scenario could
become reality. Additive manufac-
turing (AM), also known as 3D
printing, could enable future agile
operating concepts. AM has the ability
to significantly shorten the Depart-
ment of Defense (DOD) logistics chain,
especially where repair parts are con-
cerned, by producing the parts as they
are needed. This would enable rapid,
flexible response to unanticipated faults
or battle damage with reduced stockpile
requirements, increasing the agility
of the operational force. However, to

How to prepare? What to wear? What to do while there (Iโm from CO so I know I need to explore the area to look at housing, but not sure what else I should do)? Items to pack? Etiquette for this sector of work (design/AM)?
I interned with this same company at a site in Florida over the summer, so they are aware of my skills/capabilities, and have had really positive feedback to give regarding my candidacy. Iโm pretty confident I will get a job offer, I just want tips to make sure I put my best foot forward and give them no choice but to hire me.
Thank you so much!
I have signed up to take this but I am wondering how many weeks do I need to allocate for study time. There's only one text and I think it open book but I'd rather not flub and have to retake. I wish there was a practice test. Any info or perspective is appreciated.
