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

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 o…

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…

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…

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…

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 w…

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 etc…

I hope everyone has a great week. We just build some amazing parts for Trinity Ortho in Stainless Steel, using DMLS - I love how this stuff works lol Timr@gpiprototype.com

I am down to do any of the prototyping yall create :) I am very good at what I do. We do SLA, SLS, FDM, DMLS, 3d Printing and much more. We are in the US, chicago area. Check us out! Click Here for GPI Prototype - Direct Metal Laser Sintering -…

Hilarious video on DMLS process lol must check this out
I THINK IT IS AN EXTREMELY FUNNY VIDEO lol That is just my take on it. We created this a couple week ago and this is the first cut. I would love your feedback on how to make the video better and or if you like it/hate it ? You can also rate it on Yo…

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

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 piece-cost… Continue
