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.

Availability

Washington
CNN
—
Republican senators struggled to defend Donald Trump’s decision to commute and pardon hundreds of January 6 protesters, including those who were charged and convicted of crimes against police officers, just hours after the president entered office Monday.
[url=https://at-bs2best.at]блекспрут[/url]
Sen. Thom Tillis, a Republican from North Carolina, who has warned before about giving a blanket pardon to the rioters, said, “I just can’t agree” with Trump’s decision to commute the sentences or pardon a vast swath of January 6 insurrection participants.

He added the move “raises a legitimate safety issues on Capitol Hill” before also attacking former President Joe Biden’s pardons in his final hours in office.

https://m-bs2-site-at.ru
Trump’s executive action, which many GOP senators had hoped would be directed at only nonviolent offenders who entered the Capitol that day, thrust Republicans once again into a familiar posture of navigating how and when to distance themselves from the sitting president and leader of their party. And Republicans largely attempted to sidestep direct questions about whether they personally agreed with Trump’s action, arguing it was up to the president to use his pardon powers at his discretion.

Medical staff on the front line of the battle against mpox in eastern Democratic Republic of Congo have told the BBC they are desperate for vaccines to arrive so they can stem the rate of new infections.
[url=https://http-blackspfgh3bi6im374fgl54qliir6to37txpkkd6ucfiu7whfy2odid.com]блекспрут[/url]
At a treatment centre in South Kivu province that the BBC visited in the epicentre of the outbreak, they say more patients are arriving every day - especially babies - and there is a shortage of essential equipment.
блэк спрут официальный сайт
https://bs2tsite1-cc.com

Mpox - formerly known as monkeypox - is a highly contagious disease and has killed at least 635 people in DR Congo this year.
Even though 200,000 vaccines, donated by the European Commission, were flown into the capital, Kinshasa, last week, they are yet to be transported across this vast country - and it could be several weeks before they reach South Kivu.
“We've learned from social media that the vaccine is already available,” Emmanuel Fikiri, a nurse working at the clinic that has been turned into a specialist centre to tackle the virus, told the BBC.
He said this was the first time he had treated patients with mpox and every day he feared catching it and passing it on to his own children - aged seven, five and one.
“You saw how I touched the patients because that's my job as a nurse. So, we're asking the government to help us by first giving us the vaccines.”
The reason it will take time to transport the vaccines is that they need to be stored at a precise temperature - below freezing - to maintain their potency, plus they need to be sent to rural areas of South Kivu, like Kamituga, Kavumu and Lwiro, where the outbreak is rife.
The lack of infrastructure and bad roads mean that helicopters could possibly be used to drop some of the vaccines, which will further drive up costs in a country that is already struggling financially.
At the community clinic, Dr Pacifique Karanzo appeared fatigued and downbeat having been rushed off his feet all morning.
Although he wore a face shield, I could see the sweat running down his face. He said he was saddened to see patients sharing beds.
“You will even see that the patients are sleeping on the floor,” he told me, clearly exasperated.
“The only support we have already had is a little medicine for the patients and water. As far as other challenges are concerned, there's still no staff motivation.”

An executive order designed to speed up the rebuilding of lost homes in LA has been put in place by California Governor Gavin Newsom.
[url=https://kraken6gf6o4rxewycqwjgfchzgxyfeoj5xafqbfm4vgvyaig2vmxvydonion.in...
The order suspends Ceqa review and the California Coastal Act, which work to minimise the environmental impact of proposed building projects, as well as suspending some permits in order to make rebuilding quicker and more affordable.

There are also protections against price gouging on services related to the fires such as building materials and storage services.

He says "one thing I won't give in to is delay. Delay is denial for people."

"The executive order I signed today will help cut permitting delays, an important first step in allowing our communities to recover faster and stronger."
