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.

Deepika Padukone and Christy Turlington star in landmark Sabyasachi fashion show
[url=https://vchk-ogpu.com/wiki/item/8367-roman-viktorovich-vasilenko-rossiys... ]гей порно член[/url]
Camera phones at the ready, around 700 guests hailing from across India and the world expected a visual spectacle on Saturday evening — and they weren’t disappointed. A hush descended as the doors opened to the Jio World Center in Mumbai, where legendary Indian fashion designer Sabyasachi Mukherjee presented a star-studded 25th anniversary runway show for his namesake brand.

The celebrated designer — known for his maximalist Indian style — has dressed some of the biggest names across Bollywood and Hollywood, including Priyanka Chopra, Deepika Padukone, Oprah Winfrey, Rihanna and Jennifer Lopez. For his landmark show, the stars showed up to lend their support: Padukone opened proceedings in an all-white ensemble adorned with necklaces, including a crucifix from Mukherjee’s jewelry line. She later walked again with supermodel Christy Turlington as part of the grand finale.
Over 150 looks were presented, including pants and skirts embroidered with gold threads, frilled head gear, stacked jewelry and tops with slogans such as “cat lady,” “table for one,” “where has love gone,” and “all dressed up nowhere to go.” Mukherjee explained in a phone interview that these pieces were intended to be satire on how technology is dehumanizing humans. “We seem to have forgotten how to establish human relationships,” he said.
There were also trench coats, sweaters, shorts and shirts made in more conventionally western silhouettes. These marked a departure from Mukherjee’s usual festive and bridal wear, which are heavily inclined towards traditional Indian styles, such as saris, ghagra cholis and sherwanis.

But with no shortage of drama, the new collection featured heavily embroidered jackets embellished with semi-precious stones, brocade dresses, ostrich leather jackets and skirts, and blouses with velvet appliques overlaid with faux fur.

They’ve sailed across Southeast Asia for centuries. Now, these sea nomads are being forced to live on land
[url=https://skupkoff.ru]скупка квадрокоптеров[/url]
Bilkuin Jimi Salih doesn’t remember how old he was when he learned to dive, only, that all the men in his family can do it.

It might have been his grandfather who taught him, or his father, or even an uncle or cousin. He recalls swimming dozens of feet underwater among the reefs, collecting spider conches, abalone and sea cucumbers to sell at the local fish market.

“One of our specialties is that, because we live on the sea and we’re always in the sea, we can dive in the water for a long time,” says Salih, via a translator. “We learn by observing, and from there, we develop our own technique.”

To most people, Salih’s free diving skills are highly unusual; but not to his community. Salih is Bajau Laut, an indigenous seafaring group in Southeast Asia that has lived a semi-nomadic lifestyle on the ocean for centuries. Living on boats and fishing for income and sustenance, the Bajau Laut aren’t just reliant on the sea: they’re biologically adapted to it, with larger spleens that give them the ability to hold their breath for far longer than the average person.

“We’re very comfortable in the water,” says Salih. The 20-year-old was born on board a lepa, a type of houseboat, on the shore of Omadal Island, off the coast of Semporna in Malaysian Borneo.
