Re: In the market for another 3d printer

That DeVinci looks interesting. However, my new policy after getting screwed around with for 9 months is that trying to save a few hundred is a false economy. I got an M2 and should have done it a year ago. It has been running non-stop. I wanted to believe there was something better for less money, ...

Don't know why people find it so difficult to hold their camera steady, or don't know to even try.

Re: UP! Plus or CubeX Trio

PrintrBot gave everyone who bought a Beta version a free upgrade, so last night at 10:20pm I started tearing it down, and finished rebuilding it at around 6:30am. I then had a 4.5 hour conference call. Now I am going to the city for a hardware startup meeting at this interesting place that sets peop...

Re: UP! Plus or CubeX Trio

Here to custom laser cut parts will cost a lot. But you can buy a laser-cut PRUSA i3 board set for $40 - which seems like a reasonable price, but that is still more than the $23 for extrusions for an OB 1.4.

Re: UP! Plus or CubeX Trio

I bet it would cost me a lot more to get acrylic or MDF cut in small quantities.

Re: UP! Plus or CubeX Trio

My friend is printing the TAZ parts that are too large for my Printrbot Simple on an Up!:

If you have an Up!, you can make a TAZ (that normally sells for $2200) for about $800. It has 9.5x the build volume of an Up! Plus.

Re: UP! Plus or CubeX Trio

To go from 1 to 2 extruders is an extra $500. And to go from 1 to 3 is an extra $1500!

With my build I can go from 1 to 3 for an extra $250.

Re: UP! Plus or CubeX Trio

Fair enough ... I spit out mostly Mendel90s for people who want a printer. It's dead cheap, fast and easy to build, accurate and print volume is reasonable but no TAZ. I'd probably dabble in some deltas but extrusions like Misumi are extremely costly here. The 15x15mm extrusion for a OB 1.4 is just...

Re: UP! Plus or CubeX Trio

I wanted a delta printer, but not one from laser cut wood, and the Kossel Pro kit is not out yet. Even so, the print area is not all that big. I like aluminum extrusions, and this one was appealing: http://www.thingiverse.com/thing:41967 But then someone asked me why not just make a TAZ (it is 12x12...

They posted more photos of them building them with close to 40 RXLs being made.

No. My friend has one at work and if I could go back in time, I would have bought an Up! when it first came out.

Re: Nylon vs Nylon - strength test part Deux

I completed the second test. This time I made sure that the weights were closely matched through control of the extrusion multiplier. 5.86 grams for the trimmer line and 5.93 grams for the T645. That is less than 1.2% difference. This time the T645 won. I set up tow straps with my Sequoia, and the s...

Re: Nylon vs Nylon - strength test part Deux

There may be some brands that have glass in them, but it seems at least very rare, and not in the cheap stuff. If it does, it will clog your nozzle. Just avoid anything that says professional grade.

Re: Nylon vs Nylon - strength test part Deux

T645 broke. It was about 11% lighter though, so this test should be repeated with the extrusion multiplier set to about 12% higher, and then see if it still breaks first. My result so far seem to indicate that either the trimmer line is stronger, or within 12% of the strength of T645. I am not sure ...

No, it is not on an Up!, but I am hoping to inspire people to repeat the testing - which is why I share the models.

Printing on 1/32 thick Garolite

I have been printing PLA on tape, and ABS or Nylon on 65% Polyester / 35% Cotton RipStop fabric spray-mounted with 3M HiStrength-90 glue to thick glass. The fabric has been working well on certain parts, if I use a brim to reduce curling - I don't have heat yet. But I wanted to try Garolite LE. Taul...
