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 levies are also likely to reduce America’s economic output, as has happened before. A 2020 study, based on data from 151 countries, including the US, between 1963-2014, found that tariffs have “persistent adverse effects on the size of the pie,” or the gross domestic product of the country imposing them.
[url=https://kra34g.cc]kraken onion[/url]
There are a number of possible explanations for this.

One is that, when tariffs are low or non-existent, the country in question can focus on the kind of economic activities where it has an edge and export those goods and services, Gimber told CNN.

“If you raise tariffs, you’re not going to see that same level of specialization,” he said, noting that the result would be lower labor productivity. “The labor could be better used elsewhere in the economy, in areas where you have a greater competitive advantage.”
Another reason output falls when tariffs are raised lies in the higher cost of imported inputs, wrote the authors of the 2020 study, most of them International Monetary Fund economists.

Fatas at INSEAD suggested the same reason, providing an example: “So I’m a worker and work in a factory. To produce what we produce we need to import microchips from Taiwan. Those things are more expensive. Together, me and the company, we create less value per hour worked.”

Yet another way tariff hikes can hurt the economy is by disrupting the status quo and fueling uncertainty over the future levels of import taxes. That lack of clarity is particularly acute this year, given the erratic nature of Trump’s trade policy.

Surveys by the National Federation of Independent Business in the US suggest the uncertainty is already weighing on American companies’ willingness to invest. The share of small businesses planning a capital outlay within the next six months hit its lowest level in April since at least April 2020, when Covid was sweeping the globe.

“The economy will continue to stumble along until the major sources of uncertainty (including over tariffs) are resolved. It’s hard to steer a ship in the fog,” the federation said.

Whichever forces may be at work, the IMF, to cite just one example, thinks higher US tariffs will lower the country’s productivity and output.
