Nice weekend weather.

So who's up for staying indoors and smelling ABS fumes? :-)

I've got reversal working well on my stepper extruder, and a few other
trick to show off.

I'd be up for something Sunday, I think. At the Splat, or where? I have some other things that I could do simultaneously in the space. JC --- On Fri, 4/1/11, bill <bill.cul...@gmail.com> wrote:

I'm out, wedding this weekend.

No time for anything but work and dancing for me.

[Bill Culverhouse]

Jeff, let me know if you are going to splat later today.

I'd say I'll be there 3-ish, for a couple of hours. --- On Sun, 4/3/11, Bill Culverhouse <bill.cul...@gmail.com> wrote:

Sorry I missed you. I found out at lunch time that I'd be going to see

King's Speech yesterday.

 

I did manage to print an SAE Prusa this weekend. Now it's just a simple

matter of getting rods, threaded and smooth, motors, bolts, nuts, belts

plate aluminum and a partridge in a pear tree and I'll have a Mendel.

 

Though I do like the look of the Ultimaker.

 

Anyone see the improvements to the DLP Resin Printer that got posted?

Video is quite nice too:

I *do* have an old DLP projector I'm hanging onto just in case this is a doable

project in the near future.

That is bad ass.

How much does the material cost?

[Bill Culverhouse]

According to the SF stats, (I have no idea how or where that is setup)

the biggest plate cost about $6.50 and that is accounting for machine

time. There are 5 plates. 2 were 6 hour prints 4 were 2 hour prints.

there were only 3, 2 hour prints. :-)

Sorry, He mentioned getting some resin way back

that was $200 per kg and said it was probably cheaper

if you lived in the US. I don't know if he's got a 

cheaper solution now. Seems like for large items

its about as fast as a MB, but it's not affected

by complexity of the model since it cures a whole

layer at a time. So the machine sort of runs in

layers per second/minute and it doesn't matter much

how full each layer is.

 

Pretty nice. Now work on that resin price. And open source

the plans. On the pronto.
