Filament Splicer

Project cancelled, click here to read why
The idea for Filament Splicer was born about a month after our Ultimaker 3D Printer was build. As cool as 3D Printing is, printing in one color is boring.

Users of normal, single head FFF/FDM printers are stuck with single color unless they join filament pieces together to produce one multi-colored string. It is not very complicated but process is quite awkward and you will get fed up very quickly.

If you want to have proper, stable filament join you need to have right temperature on the tip of plastic when you connect pieces together. This is hard to achieve when you use some arbitrary heat source. You either underheat or overheat and burn the plastic. Using print head of your printer is best 'ad-hoc' solution but it leaves quite a mess on it, you cannot print when you splice and plastic which is in the head slowly gets burned while you take time to splice your string.

Then, of course there is issue with forming of the joint, carpet knife and fingers where our favorite tools for that job but it took quite a long time to form each joint.

We have had our share of failed prints due to broken joints / stuck filament and finally decided to create a device which will help to splice filament. Initial idea was to create fully automated unit: you place filament ends on copper block, close it, push the button and viola - you have your joint. That was the theory.... In practice this is impossible because PLA and ABS expand during heat-up and contract during cool down, this results in either no joint at all or bubble-filled mess.

Many headache filled days [Even best PLA is really nasty stuff when you breath it in for a while] later we dropped the idea and went for 'open' model with precisely manufactured grooves which help to quickly heat up, connect and form joints.

Thermal insulation was another challenge, we wanted to allow up to 260c temperature but nothing could properly insulate enclosure from hot copper block for prolonged period of time. Ceramic fiber thermal tape can take that heat but one needs a lot of it and then there is itching... Chinese tape is horrible and even best branded, made in USA [ThermoTec] tape is not flawless. We eventually gave up on ceramic fibre and went with PFTA [Teflon] plates. Since PFTA can be outright poisonous at high temperatures, we decided to use high quality - made in Europe material - this way we are sure that maximum temperature of 235c is well within safety limit.

Even during his days off, Raul Morales gets spotted by fans. On a recent visit to Universal Studios Hollywood, Morales, owner of Taqueria Vista Hermosa in Los Angeles, was waiting in line when he heard shouting.

“People called out ‘Chef Al Pastor! Chef Al Pastor!’” Morales said, laughing. Morales, who was born in Mexico City, came by the nickname through decades of hard work.

He’s the third generation of his family to make al pastor tacos, their fresh tortillas filled with richly seasoned pork shaved from a rotating vertical spit.

“My recipe is very special, and very old,” he said.

Yet while Morales’ family recipes go back generations, and similar spit-roasted meats like shawarma and doner have been around for hundreds of years, his tacos represent a kind of cuisine that’s as contemporary and international as it is ancient and traditional. When you thread meat onto a spinning spit to roast it, it turns out, it doesn’t stay in one place for long.

‘Any place you have a pointy stick or a sword’
Roasting meat on a spit or stick is likely among humans’ most ancient cooking techniques, says food historian Ken Albala, a professor of history at the University of the Pacific.

Feasts of spit-roasted meat appear in the Homeric epics The Iliad and The Odyssey, writes Susan Sherratt, emeritus professor of East Mediterranean archaeology at the University of Sheffield, in the journal Hesperia.

Iron spits that might have been used for roasting appear in the Aegean starting in the 10th century BCE. Such spits have been unearthed in tombs associated with male warriors, Sherratt writes, noting that roasting meat may have been a practice linked to male bonding and masculinity.

“I think the reason that it’s associated with men is partly because of hunting, and the tools, or weapons, that replicated what you would do in war,” Albala said. “When you celebrated a victory, you would go out and sacrifice an animal to the gods, which would basically be like a big barbecue.”

Roasting meat is not as simple as dangling a hunk of meat over the flames. When roasting, meat is not cooked directly on top of the heat source, Albala says, but beside it, which can generate richer flavors.

“Any place you have a pointy stick or a sword, people are going to figure out very quickly … if you cook with it off to the side of the fire, it’s going to taste much more interesting,” Albala said.

Ich liebe die Pracht von King Billy Casino, es verstromt eine Spielstimmung, die wie ein Palast glanzt. Der Katalog des Casinos ist eine Schatzkammer voller Spa?, mit Live-Casino-Sessions, die wie ein Festbankett strahlen. Der Casino-Kundenservice ist wie ein koniglicher Hof, mit Hilfe, die wie ein Thron majestatisch ist. Casino-Gewinne kommen wie ein Triumphzug, aber mehr Freispiele im Casino waren ein Kronungsmoment. Am Ende ist King Billy Casino ein Casino mit einem Spielspa?, der wie ein Kronungsfest funkelt fur Fans moderner Casino-Slots! Zusatzlich die Casino-Navigation ist kinderleicht wie ein koniglicher Marsch, Lust macht, immer wieder ins Casino zuruckzukehren.
