Re: Super hard nozzles - Test pilots

@@gr5 i do work for 3DVerkstan part-time since a while ago, with a focus on the Olsson Ruby nozzles and other product developments. I still run my engineering company Cederb AB the rest of the time :-)

Re: Super hard nozzles - Test pilots

gr5: no, the one on the right will not fit the UM3 cores, the UM3 nozzle has a finer pitch thread and not exactly the same length. The one in the picture is made for E3D Volcano / Lulzbot MOARstruder. We have gotten some requests for a 0.25, but we are not sure either if it really makes sense since ...

Re: Super hard nozzles - Test pilots

Today we announced new sizes (0.6 and 0.8mm) available now, and upcoming versions of the #olssonruby to fit the Volcano from E3D and the MOARstruder from LulzBot.

It should be pretty simple to frankenstein a UM2 printhead onto a CR-10

Re: Interesting Ultimaker Steel Frame Build

We use welding overalls at Stockholm Makerspace made out of flameproof heavy duty denim-like cotton, they cost about 60€ or so and provides protection for most of the body.

You want good UV protection or you may end up with a really nasty sunburn that hurts like hell...

Re: How much should a good 3D printer cost?

I have been curious about building a Ultimaker style gantry with the new Igus carbon fiber rods, the 12mm one is way stiffer than a 6mm rod and weighs less than a third. The print head weight is about the same since the larger polymer bearings are comparable In weight to the LM6UU

Re: Bearings on carriage: why 2-1 bearing arrangement?

three points define a plane, four make it overconstratined and prone to wobbling and drawer slide effect.

Re: Interesting Ultimaker Steel Frame Build

And you do NOT need 200A to make something like this, 200A is enough for 6-10mm steel or 4-6mm aluminum.

I would probably use less than 100A to weld a steel frame like this (but I am not very experienced, so take this advice for what it is.)

Re: Ultimaker just released a bunch of materials!

I would probably go for the PC, even if it is a bit harder to print.

Re: Interesting Ultimaker Steel Frame Build

It will not draw 16 amps unless you turn the amperage up to max, so a 13A circuit will work just fine if you limit the max current yourself.

Re: Interesting Ultimaker Steel Frame Build

It draws about 16A at max current, but if you run it at lower currents you can probably run it just fine at a 10A fuse. It is not the best machine, china made and exists under a infinite number of brands, but it is usable for some hobby welding. There is some newer models from the same manufacturers...

Re: Josef talks about Multiextrusion and more

I guess I like his open-ness about what he is working on. Versus selling a printer, when you know you are releasing a new one the next day (i.e. Ultimaker) :) I think when you help your customers understand what you are working on, that helps build excitement. Prusa has the luxury of having a huge ...

Re: A Tea between friends :-) How was Your Day

The Ultimaker 3 got the exact same power supply and the same heated bed, the only (larger) difference in power should be that it got two heaters for the print head.

If those are making your power flicker... Then you got a supply problem...
