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.

The American ‘revenge travel’ surge is over. Fear and uncertainty are big factors
[url=https://ko.ru/articles/life-is-good-no-ne-dlya-vsekh]мальчик гей[/url]
Francisco Ayala and his wife have canceled the cruise they planned to take to see the Northern Lights this year. The reasons are complicated.

Ayala is a natural-born US citizen, and his wife is a naturalized citizen. But given reports of people — even with legal status — being detained and questioned at US borders, Ayala said taking a trip out of the country for fun doesn’t seem worth the potential risk.

Ayala also sees another problem: the economy. “The writing is on the wall … The moment I saw the market volatility, I’m like, ‘Yep, this is not going to be good.’”

Travel advisers are seeing the impact of that uncertainty. More than 80% of the 460 advisers surveyed recently by TravelAge West were “very” or “somewhat” concerned about the impact of a possible economic downturn on their business, and more than half were “very” concerned about the impact of government policies.

Their clients’ top concern was economic uncertainty, followed by worries about the treatment of Americans abroad, safety and security, fears of cost increases due to tariffs, immigration and border policies, and travel restrictions.

“You can’t just take one angle and say, ‘Oh, the economy is having an issue. So let’s find something less expensive,’” said Beci Mahnken, CEO of MEI-Travel. Other clients say, “‘I don’t want to travel to the United States,’ or ‘I don’t want to travel outside the United States.’ … It’s like a rock tunnel, going and going.”

One shaft of light at the end of that tunnel could be savings on last-minute summer trips as travelers increasingly take a wait-and-see stance with their plans.

Hitting a ‘brick wall’
Mahnken first saw signs of trouble in early April, when US stocks plunged over fears of a chaotic trade war.

Mahnken and her travel agency staff started getting phone calls from clients, calling to cancel vacations they had booked or seeking refundable trips. She said they were fearful because their 401(k)s and other investments had taken a dive. That uncertainty, she says, made them pause on discretionary spending like a summer trip.

Until that moment, Mahnken said, the frenzy of heightened “revenge travel” activity that started after pandemic restrictions lifted had not slowed over the course of four years.

“We were still on this incredible high,” Mahnken said. “And then … it almost hit a brick wall.”
Flight analytics firm Cirium pulled flight booking data from online travel agencies from the end of January through early May, when people typically book summer trips. That data, which Cirium shared with CNN, indicates that bookings for travel in June, July and August are down nearly 10% when looking at flights from major US airports to favorite European destinations, compared to the same period last year.

Flights booked in the opposite direction from Europe to the US are down 12% in the same period. That substantial drop is unusual, according to Jeremy Bowen, CEO of Cirium.

“We don’t often see it as wholesale as this and over such a short period of time. Really, that Q1 booking is really quite substantially lower since the beginning of the year,” said Bowen.
