@kmanstudios: Yes, the CF means carbon fibre, and it is extremely abrasive, it kills a brass nozzle in just a few hundred grams. This is the difference after 300 grams, the nozzle is just trash by this point. The best solution is to get a ruby tipped nozzle like The Olsson Ruby, but if you only print quite limited amounts and want to spend less you can also go with a hardened steel nozzle.

If it is stiffness (not necessarily the same thing as strength) you have a demand for, you should look at a CF filled like the Colorfabb XT-CF20, it is insanely stiff (6.2GPa in Flexural Modulus) compared to Polycarbonate that "just" is about 2GPa. http://colorfabb.com/files/TDS-carbon-en.pdf

You should not use a FDM printed material in the mouth for any longer times due to the above stated reasons, so there is not a good answer to your question. I know that Formlabs are working on releasing a set of resins for long-term certified 3d printed dentures (one for teeth and one for the gum) this fall, and i'll think that you should be able to use the teeth one for printing provisional crowns on a Form 2.

You mean something like this? http://hackaday.com/2017/03/25/mrrf-17-the-infinite-build-volume-printer/ I did think about this earlier today, and it should be totally possible to remove the Z stage and mount something like in the link above, the downside would be that since it is angled 45 degress, you would be limited in how long things you can print before you hit the floor or it breaks off, unless you tilted the printer 45 degrees back :-)

There are also some other high-end manufacturers that use 2,85mm, like Alpeh Objects / Lulzbot, so i am not seeing the 2,85mm size going away anytime soon.

You need the PVB based filament, PLA prints will not be affected at all.

Yeah, i was thinking about the orange one, it looks a lot like the Formlabs High-Temp and that one is also pretty fragile, but can take very high temperatures

@tigertooth4: Is that fan shroud printed in Formlabs High-Temp resin?

So the competition is not open for us with UM3's then?

I would get the official extrusion upgrade kit any day over the E3D V6 kit, unless you are specialized on printing exclusively with high temperature materials.

I would not recommend to use a FDM printer for Dental Surgical Guides, you should look at a SLA printer with biocompatible resin like the Form2 instead.

There is no adhesives used.

You have "brim" turned on, this will reduce your effective print size by 2x the brim width at X and Y since it needs space for the brim. The same object works without brim:

Haha, yeah it does, i had not thought of it before

It is coated with white paint.

@neotko, i would suggest this board: http://cohesion3d.com/cohesion3d-remix/

If i would print that adapter myself today, i would probably use a rigid TPU, like the Ultimaker TPU95A, to get a bit more dampening out of it, @Neotko is right, the UMO frame is really good at acting as a amplifier for every little vibration. And i do think that the Titan will be quite a bit quieter than the UMO feeder.

I would say that if your final product is going to be made of a flexible silicone, ninjaflex will not be soft enough, just print a mold instead.

Just set the "Line width" and "wall thickness" setting to a appropriate amount, and you are good to go.

Just as a way of finding if the Z offset is the problem i would turn off active bed leveling (set it to "Never" in the menu), then do a manual bed leveling and then the manual Z offset calibration, and then try again.

I believe those lines are a rendering of the actual printed nominal width, and all the other layers are rendered "without width" and just show the path to save rendering time. Anyhow, 15.04 is a pretty old version nowadays, the Cura 2.4 layer view does show all lines at their nominal width.

The UM3 does reduce this problem by offloading many tasks to the Olimex board, for example all the handling of menus, updating the display etc are handled there instead of in the atmega, so that one can use all of its power to do the actual motion control.

Since both you guys @nallath and @sandervg are making references to OIN, have Ultimaker considered creating something similar specifically for 3D Printing? A Patent pool where any company can join and get access to using all of the patents on the premise that they will never sue any of the other members, only use their patents defensivly and that all of the members can use their patents freely, both for use in their product and to defend themselves. This is actually something i'll think is seriously lacking in the 3D Printing business world, and as much as i hate the whole current implementation of the patent system, i'll have to admit that you should protect your business, but doing it the open patent pool way would at least open up the door for inventors with small business to join and get some protection, and it could reduce the offensive patent usage in the 3d printing world.

Cura 15.x = "Legacy Cura", the original Cura software, not in active development since 2015 Cura 2.x = "New Cura", a rewrite of Cura with a lot more features, the software that is in active development

Steel nozzles does limit your heat transfer rate, and therefore your maximum extrusion rate, that is a fact.
