Learning about DMLS surface finish and finishing of Direct Metal Laser Sintered parts
Started Apr 9, 2010 0 Replies 0 Likes
Leave a comment here or on the blog and I will address them as I can. A lot of people wonder what the parts look like right out of the machine and if the steel is dense enough for finishing. We did…Continue

I have had some serious difficulties trying to find a way to polish parts that were made using DMLS. Have you had any luck using any certain technology? Let's put the MMP process aside for a…Continue

Learn about METAL PROTOTYPES"Sorry, Tim but that link didn't work, at least for me. But I was able to go to your site and play the vid. I liked the beginning, but you could punch up the humor at the end - maybe some "gleam" special effects on the product,…"

Sorry about that.""
Bill Redd replied to Timothy Ruffner's discussion Do you design for Prototype and Manufacturing or 1 design for both?"I believe Conceptual Prototyping is the key in untried technologies. In this approach, there are a minimum of 2 prototypes built, (1) the proof of concept model and test equipment (2) Advanced modeling design for pre-release testing.
Generally there…"

Timothy Ruffner replied to Leslie Langnau's discussion When designing for rapid prototyping ..."Gary,
I'd love to quote anything you have in the EOS process. If you feel that lead time and the geometries you have cannot be done conventionally then DMLS is the way to go.
If you have some files you'd like to send to get a feel for…"
Timothy Ruffner replied to Leslie Langnau's discussion When designing for rapid prototyping ..."Leslie,
They are pretty much the same, Direct Digital can be Subtractive or Additive Manufacturing but using a Digital File. CNC would probably fall in to that category. Additive Manufacturing would be a Layer Manufacturing Process ie. SLS, SLA,…"
Timothy Ruffner replied to Leslie Langnau's discussion When designing for rapid prototyping ..."Leslie,
That is why we have Direct Digital Manufacturing (DDM) and Additive Manufacturing. It is the wave of the future to save costs and time. Most likely if you can prototype it and dream it that way, you can DDM it!
The DMLS EOS M270 that we…"

How did you do the RP Metal? Did you or have you done DMLS?

Timothy Ruffner replied to Leslie Langnau's discussion When designing for rapid prototyping ..."Hi Leslie,
We do something called Direct Digital Manufacturing....This is using the EOS M270 and we manufacturer certain components. We are able to do this because developing a tool for MIM can be quite costly especially if you are only doing a few…"
Timothy Ruffner replied to Leslie Langnau's discussion When designing for rapid prototyping ..."I would say off the top of my head was a plastic wind turbine part, the wall thickness was at 12000, I had explained that he should create the prototype and see if it can build but keep in mind for manufacturing.
I kept thinking to myself that it…"
Timothy Ruffner replied to Leslie Langnau's discussion When designing for rapid prototyping ..."I had this conversation on linkedin once. I asked the question do you design for rapid prototype for the method you know of or design for end use part. It was mixed in replies some had to design for the rapid prototype (because of wall thickness…"

We just build some amazing parts for Trinity Ortho in Stainless Steel, using DMLS - I love how this stuff works lol

Conformal Cooling using DMLS and Direct Metal Laser Sintering Technology to Reduce Cycle Time
Posted on January 22, 2010 at 10:29am 0 Comments 0 Likes
Conformal Cooling
Conformal cooling is defined as the ability to create cooling/heating configurations within a tool that essentially follows the contour of the tool surface or deviates from that contour as thin/thick sections of the part may dictate for optimal thermal management. The objective typically is to cool or heat the part uniformly. Conformal cooling provides a tremendous advantage in mold tooling through significant reductions in cycle times. Other than the obvious… Continue
