Re: [Emc-users] 3D Printers

This thread renewed my interest in 3D printing. I bought the parts and did the mechanical assembly of a Hadron ORDbot a few years ago but wanted to do a nice electrical installation instead of the usual rat's nest wiring on most home brew 3D printers. Then the complete kit became available

Re: [Emc-users] 3D Printers

Laying down even amounts of metal with a mig is surprisingly difficult. Many years I had to build up some shafts so I rigged up a setup in an old lathe with the torch clamped in the tool post. The problem I found was that if you get a high spot you end up depositing more metal on the high spot

The DMG-Mori combined powdered metal/laser AM and 5-axis CNC machining is very cool, but something close to $1M for the system. There are some efforts being made at wire-fed welder AM systems. I met a fellow from such a company at a 3d printing conference two weeks ago. He was lugging around a

Re: [Emc-users] 3D Printers

Parts can be quite strong. Although, I've seen plenty of prints with a bad layer (can be as simple as the air conditioning kicking in and shrinking the plastic suddenly). You can print out objects that would be difficult to mill, such as things requiring 5-axis milling, exotic holddown
