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.

Watch out, Orlando, a new world theme park capital is rising in the Arabian desert
[url=https://tripscan44.cc]трипскан вход[/url]
For decades, Orlando has reigned as the global capital of theme parks — a place where Disney, Universal, SeaWorld and countless other attractions have drawn millions of visitors.

But a challenger for the crown has emerged from an unlikely place: the deserts of the Arabian Gulf. In a destination once known more for oil wealth and camel racing than roller coasters, Abu Dhabi is building an adrenaline-charged playground that could give Orlando a run for its money.

And it just landed the ultimate weapon: Disney.

In May 2025, when Disney announced its first new theme park in 15 years, it chose Abu Dhabi over other key theme park destinations in California, Japan and even Orlando.

There was “no question,” says Josh D’Amaro, chairman of Disney Experiences. The UAE capital, already home to Ferrari World, with the world’s fastest roller coaster; Warner Bros. World (built under license by CNN’s parent company, Warner Brothers Discovery); Yas Waterworld, an epic network of slides and pools; and more recently, SeaWorld Yas Island Abu Dhabi. It’s clear the emirate is emerging as the most serious challenger Orlando has ever faced.

Disneyland Abu Dhabi, expected to open on Yas Island in the early 2030s, will be the company’s most technologically advanced park ever. Renderings show a shimmering, futuristic tower at its center — more closely resembling Abu Dhabi’s gleaming skyline than a traditional European castle. It will be the first Disney resort set on an accessible shoreline, located just 20 minutes from downtown Abu Dhabi.

The theme park will be developed, built and operated by Miral, the Abu Dhabi company behind Yas Island’s roster of other attractions. Disney Imagineers will handle creative design and operational oversight, making sure the new park is in keeping with Disney’s brand.

Miral’s CEO, Mohamed Abdalla Al Zaabi, says demand already exists: 2024 saw a 20% rise in theme park attendance on Yas Island. And expansion is already in the works — a Harry Potter–themed land at Warner Bros. World, more record-breaking rides at Ferrari World, new themed hotels, and even two beaches along Yas Bay Waterfront.

‘This isn’t about building another theme park’

Why Disney chose Abu Dhabi for their next theme park location
7:02
Abu Dhabi’s location, a medium-haul flight away from both Europe and Asia, and relatively short hop away from India, means millions of potential visitors are within relatively easy reach.

“This isn’t about building another theme park,” Saleh Mohamed Al Geziry, Abu Dhabi’s director general of tourism, told CNN. “It’s about defining Abu Dhabi as a global destination where culture, entertainment and luxury intersect.”
