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.

Taylor Swift has been subpoenaed in the case between Blake Lively and Justin Baldoni.

Swift – a longtime friend of Lively’s – was first mentioned in connection to the ongoing legal dispute between Lively and her “It Ends with Us” director and costar when text exchanges were revealed to include the name “Taylor” as part of Baldoni’s $400 million defamation countersuit against Lively and her husband Ryan Reynolds in January.
[url=https://kra31att.cc]kra32at[/url]
One of the text messages included in Baldoni’s suit appears to show an exchange between Baldoni and Lively about the script for the film: “I really love what you did. It really does help a lot. Makes it so much more fun and interesting. (And I would have felt that way without Ryan and Taylor),” Baldoni wrote with a wink emoji. “You really are a talent across the board. Really excited and grateful to do this together.”

A spokesperson for Swift on Friday told CNN, “Taylor Swift never set foot on the set of this movie, she was not involved in any casting or creative decisions, she did not score the film, she never saw an edit or made any notes on the film, she did not even see ‘It Ends With Us’ until weeks after its public release, and was traveling around the globe during 2023 and 2024.”

“The connection Taylor had to this film was permitting the use of one song, ‘My Tears Ricochet.’ Given that her involvement was licensing a song for the film, which 19 other artists also did, this document subpoena is designed to use Taylor Swift’s name to draw public interest by creating tabloid clickbait instead of focusing on the facts of the case,” the spokesperson added.

CNN has reached out to representatives for Baldoni for comment.

When reached for comment later on Friday, a spokesperson for Lively said Baldoni and his legal team “continue to turn a case of sexual harassment and retaliation into entertainment for the tabloids.”

Two strangers met on a train. Then they decided to travel the world together
[url=https://kra32a.at]Площадка кракен[/url]
Savery Moore and his wife Jan always talked about traveling across Canada by rail.

The American couple shared a dream of waking up to the sun rising over the tracks and spending days winding through forests and across prairies, glimpsing snow-capped peaks and frozen lakes through the train’s domed glass roof. Making memories together.

For most of their 35 years of married life, Savery and Jan didn’t travel much, spending long days working in advertising.

But when the couple finally retired in their 60s, leaving New York City for a small town in Massachusetts, they were excited for a new chapter and new opportunities.

“We both retired the same day,” Savery tells CNN Travel today. “We looked forward to having our life forever, together.”

Savery and Jan finally looked into booking their dream trip on VIA Rail’s “Canadian” service, a luxury train journey that winds from the West Coast of Canada to the East over four days.

“We were going to spend some money and take The Canadian in a class called ‘prestige,’ which is VIA Rail’s most expensive way to travel,” says Savery.

This was a “bucket list trip,” explains Savery. The couple wanted to splurge, figuring “we were only going to do this once, so let’s just do it right.”

But just as they started planning the trip, life took an unexpected turn.

“Jan was diagnosed with cancer, and it was lung cancer, and it was aggressive,” explains Savery. “Within a month-and-a-half to two months after her being diagnosed, the cancer had already spread.”

In the months that followed, Jan had brain surgery. She was enrolled in a couple of clinical trials.
