Re: PTFE coupler - Theory and practical details

Without arguments is hard to argue :-) So, or you bring some concrete fact or there isn't progress in the discussion and accordingly in the search for a better solution that can involve more people :-) Well, you make a lot of odd claims that suggests that you have very little experience in machinin...

Re: PTFE coupler - Theory and practical details

Injection molding in my opinion much more expensive, if we are talking about making hotends. Turning metal is worth a penny, and the level tolerances of the product not so much affect the final cost, at least where I live. I admit that in Europe/USA, the situation may be radically different from mi...

Re: PTFE coupler - Theory and practical details

WHAT?? :-D sorry but I not agreed with your statement about the complexity of your "Olsson block"... seriously there is nothing complex about it... nor in the design, nor in the manufacturing process. Without explaining manufacturing complications in detail, let's just say that there is a...

Re: PTFE coupler - Theory and practical details

I never bought a hotend from E3D for the simple reason that I never thought that an interchangeable nozzle as proposed by E3D could work without leaks...besides the fact that achieve the precise connections between the steel part and the aluminum side and the nozzle side of so reduced size, it woul...

Re: PTFE coupler - Theory and practical details

I not even take into account the ruby nozzle ... in the printing of thermoplastics I do not see the use of nozzles Sapphire / Ruby, and certainly not for the cost since the synthetic rubies cost nothing (more than anything else could be costly one initial investment to get a custom made ruby) nor f...

Re: PTFE coupler - Theory and practical details

I guess there is a risk this becomes a UM3 print core thread now, but anyway.. :-) Anyway, regarding the lifting mechanism, the circuit board is stationary and the cables between circuit board and heater/sensor are flexing, so the contact surfaces are not going to wear much. When I say well enginee...

Re: PTFE coupler - Theory and practical details

So, as I promised earlier, now when the Ultimaker 3 is official. The Ultimaker 3 approach is PTFE lining which has proper cooling and then a very short and efficient heat break zone. I should not share accurate drawing of it, but here is approximately how it looks: 2016-10-05-8975.jpg It is basical...

Re: PTFE coupler - Theory and practical details

how you will define an upgrade kit that is sold at a price that is 1/4 of the total cost of a new device, with parts that are not necessary because already present? The part of redundant parts would i describe as that it was designed to be user friendly to install... And the price, well you did not...

Regarding the TFM, here is a short summary of it's properties from one of the suppliers: http://www.fluorotec.com/products/valve-seats/ TFM Is a modified TFE Polymer. Often referred to as second generation PTFE, TFM retains all the primary benefits of PTFE in chemical resistance etc. However TFM ha...

Re: UM2 print head project

At the end of the day if they want to rip it off they would just buy one, strip it down and measure and document everything to then get the all the info. The only people that will stop them is those that dont buy their rip offs, if we didn't buy them it wouldn't be worth their effort and money to r...

Re: PTFE coupler - Theory and practical details

I can not discuss certain things as freely as I would like right now. Stepping into Ultimaker R&D-department comes with certain obligations. In one week we can start discussing a rather nice solution to the PTFE-problem, but not before that: http://www.3dprintingforum.us/viewtopic.php?f=12&...
