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.

Americans nearing retirement and recent retirees said they were anxious and frustrated following a second day of market turmoil that hit their 401(k)s after President Donald Trump’s escalation of tariffs.

[url=https://kra26at.com]kra26 at[/url]
As the impending tariffs shook the global economy Friday, people who were planning on their retirement accounts to carry them through their golden years said the economic chaos was hitting too close to home.

[url=https://kraken7.net]kra7 at[/url]
Some said they are pausing big-ticket purchases and reconsidering home renovations, while others said they fear their quality of life will be adversely affected by all the turmoil.

“I’m just kind of stunned, and with so much money in the market, we just sort of have to hope we have enough time to recover,” said Paula, 68, a former occupational health professional in New Jersey who retired three years ago.

Paula, who spoke on the condition of anonymity because she feared retaliation for speaking out against Trump administration policies, said she was worried about what lies ahead.

“What we’ve been doing is trying to enjoy the time that we have, but you want to be able to make it last,” Paula said Friday. “I have no confidence here.”

Trump fulfilled his campaign promise this week to unleash sweeping tariffs, including on the United States’ largest trading partners, in a move that has sparked fears of a global trade war. The decision sent the stock market spinning. On Friday afternoon, the broad-based S&P 500 closed down 6%, the tech-heavy Nasdaq dropped 5.8%, and the Dow Jones Industrial Average fell more than 2,200 points, or about 5.5%.

A tiny rainforest country is growing into a petrostate. A US oil company could reap the biggest rewards
[url=https://swell-net.com]swell[/url]
Guyana’s destiny changed in 2015. US fossil fuel giant Exxon discovered nearly 11 billion barrels of oil in the deep water off the coast of this tiny, rainforested country.

It was one of the most spectacular oil discoveries of recent decades. By 2019, Exxon and its partners, US oil company Hess and China-headquartered CNOOC, had started producing the fossil fuel.? They now pump around 650,000 barrels of oil a day, with plans to more than double this to 1.3 million by 2027.

Guyana now has the world’s highest expected oil production growth through 2035.

This country — sandwiched between Brazil, Venezuela and Suriname — has been hailed as a climate champion for the lush, well-preserved forests that carpet nearly 90% of its land. It is on the path to becoming a petrostate at the same time as the impacts of the fossil fuel-driven climate crisis escalate.

While the government says environmental protection and an oil industry can go hand-in-hand, and low-income countries must be allowed to exploit their own resources, critics say it’s a dangerous path in a warming world, and the benefits may ultimately skew toward Exxon — not Guyana.

Когда вы собираетесь в поездку в Минеральные Воды, важно не только продумать маршрут и достопримечательности, но и знать, как сэкономить на транспорте. Такси может стать удобным решением, но цены на услуги могут сильно варьироваться. Вот несколько советов, как выбрать такси и сделать поездку более бюджетной.

Сравнивайте цены в нескольких приложениях. Перед тем как заказать такси, проверьте разные приложения для вызова такси. В таких сервисах, как Yandex.Go, Uber или Bolt, могут быть разные тарифы на один и тот же маршрут. Не поленитесь провести небольшое маркетинговое исследование!
Заказывайте такси заранее. Многие сервисы предлагают более выгодные тарифы для предварительных заказов. Если вы знаете, в какое время вам нужно добраться до точки назначения, сделайте заказ заранее и сэкономьте на расценках по повышенному тарифу.
Ищите акции и скидки. Многие приложения для такси проводят акции, при которых вы можете получить скидку на первую поездку или специальные промокоды для частых пассажиров. Перед поездкой загляните в раздел акций в вашем приложении.
Предпочитайте эконом-класс. Если вас не смущает немного менее комфортное время в пути, выберите эконом-класс. Он значительно дешевле стандартных классов и для коротких расстояний может быть отличным вариантом.
Объединяйтесь с другими пассажирами. Если вы путешествуете с друзьями или знакомыми, заказывайте одно такси на несколько человек. Это не только снизит стоимость на человека, но и сделает поездку более приятной.
Планируйте свои поездки заранее и следуйте этим простым советам, чтобы сократить расходы на [url=https://taxi-minvodi-aeroport.ru/]такси Минеральные воды аэропорт[/url]. Получите максимум удовольствия от поездки, не разоряя при этом свой бюджет.
