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.

Disney made a smart choice’
Despite the comparisons, Abu Dhabi isn’t positioning itself as a direct rival to Orlando — it’s aiming to be something more. The emirate sees its theme parks as part of a bigger portfolio of attractions, alongside cultural landmarks, luxury hotels, pristine beaches, and desert adventures.
[url=https://trip-scan44.co]трипскан[/url]
A 15-minute drive from Yas Island, Saadiyat Island is home to the Louvre Abu Dhabi, a franchised outpost of the famous Paris art museum, which welcomed 1.4 million visitors last year, 84% from abroad. The Guggenheim Abu Dhabi and Zayed National Museum are both under construction, adding to a cultural district that will be one of the region’s most concentrated hubs of art and heritage.

“Abu Dhabi’s unique appeal lies in the diversity of our tourism offering,” Al Geziry added. “For thrill-seekers, we have record-breaking roller coasters and dune bashing in the desert. For culture lovers, historic sites like Al Ain Oasis and institutions like the Saadiyat museums. And for luxury travelers, world-class dining, private island resorts, and high-end shopping.

“Where else can you start your day under the Louvre’s iconic rain-of-light dome and end it in the immersive, story-driven worlds of Warner Bros. World or Ferrari World?”

Still, not everyone is convinced that Disney’s expansion into the Middle East is a sure bet.

“The region has seen its share of false starts,” says Dennis Speigel, founder of the International Theme Park Services consultancy, comparing it to neighboring Dubai’s patchy record with theme park expansion ambitions in the mid-2010s. “Several of them struggled for profitability in their first decade.”

Spiegel believes Abu Dhabi is different. “Disney made a smart choice. The infrastructure, safety, and existing leisure developments create an ideal entry point,” he told CNN earlier this year. “It’s a much more controlled and calculated move.”

Under its Tourism Strategy 2030, Abu Dhabi aims to grow annual visitors from 24 million in 2023 to more than 39 million by the end of the decade. With Disneyland as a centerpiece, those targets may well be surpassed. The city’s population has already grown from 2.7 million in 2014 to more than 4.1 million today, a reflection of its rising profile as a regional hub.

Yas Island alone has been transformed in the space of a decade from a largely undeveloped stretch of sand to a self-contained resort destination, complete with golf courses, marinas, a mall, more than 160 restaurants, and a cluster of high-end hotels.

Orlando’s head start remains formidable — it still offers multiple Disney and Universal parks, has decades of brand loyalty, and an infrastructure built to handle tens of millions of tourists annually.

But Abu Dhabi is catching up fast. Its combination of frictionless travel, year-round comfort, cutting-edge attractions, and a cultural scene that adds depth to the experience gives Abu Dhabi its own unique selling point, potentially offering a model for the next generation of theme park capital.

Don Mueang International Airport, Thailand (DMK)
[url=https://trip-scan44.co]трипскан вход[/url]
Are you an avgeek with a mean handicap? Then it’s time to tee off in Bangkok, where Don Mueang International Airport has an 18-hole golf course between its two runways. If you’re nervous from a safety point of view, don’t be — players at the Kantarat course must go through airport-style security before they hit the grass. Oh, you meant safety on the course? Just beware of those flying balls, because there are no barriers between the course and the runways. Players are, at least, shown a red light when a plane is coming in to land so don’t get too distracted by the game.

Although Suvarnabhumi (BKK) is Bangkok’s main airport these days — it opened in 2006 —Don Mueang, which started out as a Royal Thai Air Force base in 1914, remains Bangkok’s budget airline hub, with brands including Thai Air Asia and Thai Lion Air using it as their base. Although you’re more likely to see narrowbodies these days, you may just get lucky — in 2022, an Emirates A380 made an emergency landing here. Imagine the views from the course that day.

Planning a trip to Jarlshof, the extraordinarily well-preserved Bronze Age settlement towards the southern tip of Shetland? You may need to build in some extra time. The ancient and Viking-era ruins, called one of the UK’s greatest archaeological sites, sit just beyond one of the runways of Sumburgh, Shetland’s main airport — and reaching them means driving, cycling or walking across the runway itself.

There’s only one road heading due south from the capital, Lerwick; and while it ducks around most of the airport’s perimeter, skirting the two runways, the road cuts directly across the western end of one of them. A staff member occupies a roadside hut, and before take-offs and landings, comes out to lower a barrier across the road. Once the plane is where it needs to be, up come the barriers and waiting drivers get a friendly thumbs up.

Imagine flying into Majuro, the capital of the Marshall Islands in Micronesia. You’re descending down, down, and further down towards the Pacific, no land in sight. Then you’re suddenly above a pencil-thin atoll — can you really be about to land here? Yes you are, with cars racing past the runway no less, matching you for speed.

Majuro’s Amata Kabua International Airport gives a whole new meaning to the phrase “water landing”. Its single runway, just shy of 8,000ft, is a slim strip of asphalt over the sandbar that’s barely any wider than the atoll itself — and the island is so remote that when the runway was resurfaced, materials had to be transported from the Philippines, Hong Kong and Korea, according to the constructors. “Lagoon Road” — the 30-mile road that runs from top to toe on Majuro — skims alongside the runway.
Don’t think about pulling over, though — there’s only sand and sea on one side, and that runway the other.

Watch out, Orlando, a new world theme park capital is rising in the Arabian desert
[url=https://tripscan44.cc]tripskan[/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.
https://tripscan44.cc

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.

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.”
