Learning about DMLS surface finish and finishing of Direct Metal Laser Sintered parts

Started Apr 9, 2010 0 Replies

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

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…"

Conformal Cooling using DMLS and Direct Metal Laser Sintering Technology to Reduce Cycle Time

Posted on January 22, 2010 at 10:29am 0 Comments

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

Good day,

I picked interest on you after going through your short profile and demand it necessary to write you immediately. I have something very vital to disclose to you, but I found it difficult to express myself here, since it's a public site.Could you please get back to me on (kayimivedor@gmail.com) for the full details.

Have a nice day.
Mrs.Kayi
