Re: Heated build chamber patent limitation - 10 years ago

Quote3ntrlab The real limiting factor is the installed power (> 1 KW) you need to reliably heat the printing volume... I can hold 30C over ambient with 100w. Not sure why you'd need 1kw.

Re: With All-Metal hotend with ABS, why not just run max temp? - 10 years ago

Thermal decomposition resulting in carbon monoxide/hydrogen cyanide, for starters. Later on, autoignition.

Re: Whats dictating the price of filament now? - 10 years ago

QuoteBill Clark The only thing I find expensive about filament is the initial cost for the variety I have. As for actual usage, for me , a spool lasts a long time. My prints are never really 'large' so I may get 25 or more parts from a single spool. Don't actually know for sure. Havent finished a spool yet. Relative to the time I have invested in those 25 or so parts, electricity to run the mach

Re: Why are filament extruders so slow? - 10 years ago

QuoteMrDoctorDIV What about filament extrusion makes it so slow when regular printing extruders can go so much faster? "Much faster"? Do you have a printer that can churn through 1kg in under 8 hours? Motor power is roughly equal to the cube of extrusion speed. That means quadrupling extrusion speed requires a motor 64 times more powerful. That gets expensive quickly.

Re: Affordable plastic shredder - 10 years ago

For best results, 5mm or smaller. You could probably feed some 7.5mm pieces, but if the average feed size gets too large, it will start to have inconsistent filament diameter because melt pressure is changing too much.

Re: QU-BD Problems - 10 years ago

What is the explanation for the RPM buyers that have not gotten refunds after 5 months of waiting for refund and 16 months of QU-BD holding their money?

QuotestonedcoldskierLastly, I noticed that they have changed their url from "qu-bd.com" to "quintessentialuniversalbuildingdevice.com". I'm guessing it was an attempt at a fresh start, but maybe they just liked the way it rolls so smoothly off the tongue. 3D Systems threatened them with legal action, as the name was too similar to

Re: Update on the E3D All Metal Hotend (Now finally shipping!) [Lots of pictures] - 10 years ago

Quote3DogNateI did get a response from E3D they asked about the filament path. Which with the bulldog there is no more than a mm or so anywhere that the filament is unsupported to allow for a flex or bind in the path... Didn't you bore/tap the heatsink for a bowden connector? That would leave many millimeters unsupported.

This is exciting, you have broken the laws of thermodynamics! Huh??? are you saying that if you blow a fan on a room temperature block of aluminum that it is impossible to cool it to below

You have the fan wired to constant 12v, not heater power, right? You also forgot to mention that you modified the heat sink. Pictures?

Quoteplexus Hi Jkoljo. think of filament as being steel cable: its harder to pull thick steel cable off a spool than thinner steel cable because the thicker stuff is less flexible. so the motor needs more torque to pull the thicker material off the reel. this is why we have to use a geared extruder to get more torque from the motor, in exchange for speed. 1.75 is easier to pull off so you can use

Re: Nazi Mods - 10 years ago

Quoteohioplastics I think the bill of rights has precedent in all public spaces. This isn't a public place, and I wouldn't say the moderators are self righteous at all. I would say most folks here are onboard with the majority of your posts being deleted, as typically very few lend themselves to constructive dialogue.

Quotebiszkopt80 Any news when i will be able to buy your hotend Sanjay? On your shop from long time is pre-order,but i can get all parts separate. They're out of fans at the moment, which is why you can do that (but you can't get the fan). Filastruder has the full hotends in stock though.

QuoteKingRahl Remember, they did spend thousands of dollars creating a pen to right upside down in space instead of just using a pencil. That is incorrect. Unless you mean thousands of dollars ($1200) for 400 pens, which isn't bad at all. And isn't really thousands.

Re: .4mm filament - 10 years ago

Quoteohioplastics Since the pressure would be zero or near zero, there shouldn't be any breakage (theoretically). I know it's not possible now, but neither was a smartphone 30 years ago. What? I think you are mixing up force and pressure. You still have all the viscous drag that you always have. You have less turbulent flow as you are no longer performing a crossectional area reduction, but you
