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 trial of Bryan Kohberger – the man who brutally murdered four University of Idaho students inside their off-campus home – ended in July before it ever truly began when he accepted a plea deal that saw him sentenced to four consecutive life terms in prison without the possibility of an appeal or parole.

Kohberger sat impassively throughout the hearing as the loved ones of each of the four students whose lives he so callously ended repeatedly asked him the same question: Why?
[url=http://trip-skan45.cc]tripscan[/url]
And when he was finally given the opportunity to answer their questions, he said, “I respectfully decline.”

That decision further fueled the mystery around his motive for murdering Xana Kernodle, Madison Mogen, Ethan Chapin and Kaylee Goncalves.

“There’s no reason for these crimes that could approach anything resembling rationality,” Idaho District Judge Steven Hippler said during Kohberger’s sentencing. “The more we try to extract a reason, the more power and control we give to him.”

But, he added, investigators and researchers may wish to study his actions – if only to learn how to prevent similar crimes from occurring in the future.

Indeed, academics and former FBI profilers told CNN the challenge of unravelling the criminal mind of a man like Bryan Kohberger is enticing. And while his trial may be over, in many ways, the story of what can be learned from his crimes may have only just begun.

“We want to squeeze any silver lining that we can out of these tragedies,” said Molly Amman, a retired profiler who spent years leading the FBI’s Behavioral Threat Assessment Center.

“The silver lining is anything we can use to prevent another crime. It starts with learning absolutely, positively everything about the person and the crime that we possibly can.”

CNN
Only Kohberger knows
Even seasoned police officers who arrived at 1122 King Road on November 13, 2022, struggled to process the brutality of the crime scene.

All four victims had been ruthlessly stabbed to death before the attacker vanished through the kitchen’s sliding glass door and into the night.

“The female lying on the left half of the bed … was unrecognizable,” one officer would later write of the attack that killed Kaylee Goncalves. “I was unable to comprehend exactly what I was looking at while trying to discern the nature of the injuries.”

Initial interviews with the two surviving housemates gave investigators a loose timeline and a general description of the killer – an athletic, White male who wore a mask that covered most of his face – but little else.

Police later found a Ka-Bar knife sheath next to Madison’s body that would prove to be critical in capturing her killer.

One of the surviving housemates told police about a month before the attacks, Kaylee saw “a dark figure staring at her from the tree line when she took her dog Murphy out to pee.”

“There has been lighthearted talk and jokes made about a stalker in the past,” the officer noted. “All the girls were slightly nervous about it being a fact, though.”

But after years of investigating the murders, detectives told CNN they were never able to establish a connection between Kohberger and any of the victims, or a motive.

Kohberger is far from the first killer to deny families and survivors the catharsis that comes with confessing, in detail, to his crimes. But that, former FBI profilers tell CNN, is part of what makes the prospect of studying him infuriating and intriguing.

<a href=https://t.me/transy_volgograd>трансы Волгоград</a> Трансы – это сложные и многогранные состояния сознания, выходящие за рамки обычного бодрствования. Их природа двойственна: они могут возникать спонтанно, как мимолетные проблески иной реальности, или индуцироваться целенаправленно, с помощью арсенала проверенных временем техник. Гипноз, медитация, ритмическая музыка, страстный танец, даже вещества, изменяющие сознание, – все это инструменты, способные погрузить человека в транс. На физиологическом уровне это состояние характеризуется замедлением сердечного ритма, изменением картины мозговой активности, расслаблением мышц. На уровне психологическом – обостряется восприимчивость, время течет иначе, границы между собой и миром размываются.
