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 directives largely roll back efforts made over the last decade attempting to eradicate toxic culture in the military, both to decrease harmful behaviors like harassment, but also to meet practical needs of getting people in uniform and keeping them there longer as the military branches faced years of struggles filling the ranks.

Many major reforms were described by the officials who implemented them as driven by that need; when former Defense Secretary Ash Carter opened up combat roles to women in 2015, he said the military “cannot afford to cut ourselves off from half the country’s talents and skills” if it wanted to succeed in national defense.

And while the military had made changes in recent years in an attempt to lessen instances of harassment, discrimination or toxic leadership by creating reporting mechanisms so that troops would come forward, Hegseth said those efforts went too far and were undercutting commanders.

“The definition of ‘toxic’ has been turned upside down, and we’re correcting that,” Hegseth vowed on Tuesday, adding that the Defense Department would be undertaking a review of words like “hazing” and “bullying” which he said had been “weaponized.”

The Oktoberfest beer festival in Munich will remain shut on Wednesday until at least 5 pm (1500 GMT) after police said they discovered explosives in a residential building in the north of the city that caught fire and left one person dead.

As part of a major operation that police earlier said posed no danger to the public, special forces were investigating an area in the north of Munich where Bild newspaper and multiple other reports said shots and explosions had been heard.
[url=https://at-kra37cc.ru]kra41 at[/url]
Police said the residential building had been deliberately set on fire in a family dispute and one person who was found there had died and another was missing, but not believed to be in danger.

Special forces had to be brought in to defuse booby traps found in the building, according to police.

“We are currently investigating all possibilities. Possible connections to other locations in Munich are being examined, including the Theresienwiese (where the Oktoberfest is located),” said Munich police on the WhatsApp messaging service.

“For this reason, the opening of the festival grounds has been delayed,” police added.
