Artificial Intelligence the Game Changer

AI, VR and 3D printing are among the hottest areas in technology today. They may occupy different positions on Gartner’s famous “hype cycle” curve but all three are getting significant investment and media coverage.

3D Printed Dust Collector For CNC Spindle

I ordered a dust collector from China almost a month ago, and it still has not arrived.  I really need one as I am hesitant to machine anything here right now as the dust is overwhelming me.

Yesterday, I sat down and drew in CAD a 3D printed version.

Then I attempted to print it.

With disastrous results.

My new printer arrived from china as a kit and I assembled it.  I noticed that the printed extruder wasn't done very well, but being in a hurry (never be a moron in a hurry)  I opted to use it instead of fabricating a adapter plate and messing with that.

I had 3 failed prints in a row that pretty much wasted my time until 1 in the afternoon.  I discovered then that the supplied extruder was crap, and deformed once the motor got warm, softening the plastic.

I fabricated a new plate, installed it and then other neglected issues popped up with the printer.  Namely one part was kind of poorly printed and I had been holding off for the machine to actually fail before disassembling everything and putting in the new parts.  The Chinese supplier had sent me a set of files to print my own replacement parts, so I had made those as one of the first things I did.

I had printed them at 100% solid vs the low infill that the China parts arrived in so they are much more stronger.  I probably will end up machining replacement parts from nylon or aluminum on the mill if I get some time and initiative.

So right now I have 2 of the 3 pieces made.  The remaining adaptter to hold the vacuum cleaner hose is 30% printed as I type this.

Here are the files.

Basically the vacuum cleaner suction is directed to around the bit and then a flexible brush skirt is attached to keep the chips from flying away before the vacuum can suck them.

Its only a $20 item to buy in sheet metal, but I need it now not a month from now.

Karl Rove > Quotes > Quotable Quote

Karl Rove

“We’re an empire now, and when we act, we create our own reality. And while you’re studying that reality — judiciously, as you will — we’ll act again, creating other new realities, which you can study too, and that’s how things will sort out. We’re history’s actors . . . and you, all of you, will be left to just study what we do.”
