Tourists may soon bring home personalized souvenirs with native designs, unique pots and sculptures using sustainable plastic. Moving forward, it can be marketed worldwide via online platforms. IN year 2006, the movie 'Mission: Impossible III' featured a 3D printed mask fabricated based on a 3D scan of Phillip Hoffman's character for Tom Cruise's Ethan Hunt to wear. The three-dimensional (3D) printing has leapt from science fiction to factory floors and even into our homes during the last decades. This transformative technology has enabled people from students to surgeons, to produce objects with unprecedented ease and customization.
Advertisement From Bones to Buildings: Real-World Wonders One of the most impactful applications of 3D printing is in the medical field. Doctors today use 3D-printed titanium plates and polymer-based splints for complex fractures such as skull and hip, improving recovery and comfort. The field of organ printing is pushing scientific boundaries even further. Researchers have successfully printed human tissues like liver and skin using bio-inks made from living cells experimentally, paving the way for future on-demand organ replacements. In aerospace, companies like General Electric (GE) have been printing fuel nozzles for jet engine that are 25% lighter and five times more durable than conventionally manufactured ones.

In the culinary world, 3D-printed food is transforming how meals are made. Machines can now print chocolate, pasta, and plant-based meats. In Bristol, scientists have developed 3D-printed meals with customized textures and nutrition for patients with dysphagia, a medical condition that makes swallowing difficult. On the larger scale, construction firms in the Netherlands, China, and Dubai have completed full-scale buildings using giant 3D concrete printers. This technology offers potential solutions to housing shortages by reducing labour and material costs significantly. Accessible Technology for All The widespread availability of 3D printers today is largely thanks to the expiration of two major patents: fused deposition modeling (FDM) and stereolithography apparatus (SLA). These advancements have driven down the cost of printers and opened the doors to schools, universities, and hobbyists. Technically known as 'additive manufacturing', 3D printing works by adding material layer by layer to build a 3D object directly from a digital file. This stands in contrast to traditional subtractive and formative manufacturing, which relies on cutting, drilling, molding and forging materials into shape. There are seven distinct additive manufacturing processes defined by the ISO standard. FDM is the most affordable form of 3D printing. It works by melting a thermoplastic filament and extruding it through a heated nozzle. The printer lays down the material layer by layer on a build platform, where it cools and solidifies. Meanwhile, SLA uses a laser or ultraviolet (UV) light to cure liquid resin at high precision and result in smooth finishes, making them ideal for dental models, jewellery, and intricate figurines. The future of 3D printing lies beyond basic plastic. High-performance materials such as PEKK, ULTEM, ceramics, metal powders, and carbon-fiber composites are now being used for functional industrial parts, from aerospace components to surgical tools. These materials opening new frontiers in engineering by offering greater strength, heat resistance, and biocompatibility. Advantages of 3D Printing Unlike conventional manufacturing, which often wastes materials through cutting and shaping, 3D printing uses only the amount of material needed. Additionally, it allows manufacturing on demand, eliminating the need for large inventories or overseas shipping. This has enabled many home business startups during the Covid-19. From the perspective of engineering, the design freedom given by the 3D printing is unmatched. Complex geometries and custom features designed by engineers can be printed directly without special tools or molds. Malaysia's Growing 3D Printing Economy In Malaysia, innovative individuals and startups are already turning 3D printing into profitable ventures. For instance, a Penang-based entrepreneur produces custom-fit insoles and orthotics using foot scans and 3D printers. In Kuala Lumpur, a company creates architectural models for developers. Besides, a company in Selangor designs and prints 3D implants for hospitals. Several companies offer design and printing services for production jigs, inspection fixtures, and prototypes. Meanwhile, small home-bound businesses offer personalized 3D-printed home decors and gifts, such as designers' lamps, photo frames, nameplates and toys, through online platforms. Can Sabah Benefit from the 3D Printing Revolution? Sabah's economy traditionally relies on tourism, agriculture, oil and gas, and manufacturing. The 3D printing can help to complement the existing economic sector by providing diversified options and modernization of the local industry. Entrepreneurs can make products with local motifs. Tourists may soon bring home personalized souvenirs with native designs, unique pots and sculptures using sustainable plastic. Moving forward, it can be marketed worldwide via online platforms. Local artisans and film studios can make fantastical art pieces and iconic mask using 3D printing technology to support the creative industry, just like Marvel did for Black Panther, Deadpool and Iron Man. Local workshops can reproduce rare or discontinued machine parts for factories and plantations. The development of 3D printing industry in Sabah will help to support the regional needs of critical components. For example, Shell Jurong Island, a dedicated chemical manufacturing facility in Singapore able to replace their critical heat exchanger parts by engaging 3D metal printing technology that delivers within two weeks manufacturing lead time. Besides, 3D printed molds, jigs and fixtures can support the needs of local manufacturers. Engineers can innovate new tools, components and customized machines for agricultural industries, and Micro, Small and Medium Enterprises (MSMEs). Several examples include 3D printed fruit pluckers, impellers, and small machineries. Talents for the Transformation To drive this digital transformation, we need a new generation of entrepreneurs and problem-solvers who can creatively apply 3D printing. They will spearhead the Malaysia's future innovations. Equally vital are 3D part designers, who must be adept in computer-aided design (CAD), finite element simulation, and structural optimization. They, with mechanical engineering background, will translate ideas and concepts into printable reality. Design strategies and production planning are needed for large quantity and quality production. Material engineers play a key role in developing and refining printable materials that meet various industrial standards, in term of strength, safety, or sustainability. Finally, mechanical and manufacturing engineers are needed to integrate 3D printing innovations into traditional production lines for improving quality control, efficiency and productivity. They are responsible from material selections to the in-house 3D printed product qualification to ensure the printed components are suitable. Conclusion With internet access and open-source platforms, all parts of Malaysia shall be able to participate in the global digital manufacturing movement. By embracing 3D printing, states like Sabah can bridge the technological divide with industrial states and create a uniquely local version of Industry 4.0. # Ir Dr Chua Bih Lii is a Senior Lecturer at Faculty of Engineering, Universiti Malaysia Sabah and Sabah Branch Chairman of Technological Association Malaysia * Follow us on our official WhatsApp channel and Telegram for breaking news alerts and key updates! * Do you have access to the Daily Express e-paper and online exclusive news?

Australia ban bid faces new wildcard: Teenagers
WHEN 13-year-old Jasmine Elkin tried out the age-checking software Australia might use to ban children and teenagers from social media, she was surprised some products could identify a person's age to the month — but she still doubts it will work. "People are always going to find a way to get past it," said the Perth schoolgirl who trialled five photo-based age estimation products with about 30 other students last month. "They can get their brother or sister to take a photo. There's nothing really that you can do about it." Elkin's view echoes one of the main concerns of child protection advocates, tech firms and even the trial organisers about the technology Australia hopes will enable the world's first national social media ban for under-16s: the software works, they say, but young people will find a way around it. From December, social media companies like Meta's Facebook and Instagram, Snapchat and TikTok will face a fine of as much as A$49.5 million if they fail to take what the law calls "reasonable steps" to block younger users in an effort to protect their mental and physical health. The platforms say users need to be at least 13 years old to sign up for an account. How well the ban works could reverberate across some of the world's largest companies and the governments seeking to contain them: already Britain, France and Singapore are making efforts to keep children and teens off social media, while American states, including Florida, are challenging free speech laws by pushing for a ban. Even the law's opponents are likely to be watching closely: X owner Elon Musk, who is a vocal opponent of platform moderation and regulation, has criticised the measure and called the regulator overseeing it a "censorship commissar". "Everybody is looking at Australia," said Colm Gannon, chief executive officer of the International Centre for Missing and Exploited Children Australia, a member of the trial's stakeholder adviser group. "Australia should be really focusing on robust technology, robust testing and making sure the scope of the actual project is in line with the needs that they're trying to address." The organisers of the trial, which ended this month, say it was designed to determine whether the software worked as promised, and that nearly 60 products were pitched. But it also underlined the teenagers' tech skills — testers were so fast completing their assignments, organisers doubled the number of products they tested and halved session times as the project progressed. "It hasn't been our intention to pull apart the software, rip the guts out and work out every different way that you could circumvent it," said Andrew Hammond, general manager at tech contractor KJR, which ran the trial. They are expected to deliver a detailed report to the government by the end of next month. That will inform the eSafety Commissioner's advice to the government, which cited risks from cyberbullying, harmful depictions of body image and misogynist content in pushing forward with the legislation. "We know that social media age restrictions will not be the end-all be-all solution for harms experienced by young people online, but it's a step in the right direction to keep our kids safer," said a spokesman for Communications Minister Anika Wells. For some of the young Australians who participated, the trial was a glimpse into a world six months in the future where, according to the law, they will no longer be allowed to use a platform they have come to rely on for daily communication. "I use it a lot, but I can still live without it," said Canberra school student Charlie Price, 14, who trialled four software options in a room with about 60 peers and had his age guessed accurately (someone in his testing group was wrongly assessed at over 20). "I know people that will get really shocked and upset," added Price, who uses Snapchat, Instagram and messaging platform Discord and plans to collect phone numbers of his online associates before December. Like Elkin, he said he thought some teenagers might try to get around the block.

Malaysian timber exports may gain edge in US market, says FRIM forest products director
KUALA LUMPUR: Malaysia's timber exports may gain a competitive edge in the US market due to higher tariffs imposed on regional rivals such as Vietnam and Indonesia. Vietnam, once a leading furniture exporter in the region, now faces tariffs as high as 46% compared with Malaysia's import levy of 24%, Forest Research Institute Malaysia (FRIM) director of forest products division Wan Tarmeze Wan Ariffin said. 'US President Donald Trump imposed higher tariffs on Vietnam probably because they're afraid China might use Vietnam as a manufacturing hub' to bypass American trade restrictions,' he told Bernama. The United States is the largest buyer of Malaysian furniture, accounting for over half of furniture exports. However, the tariffs announced on April 2 have been paused for 90 days till early July to allow America's trading partners to negotiate for lower tariffs. 'If they don't impose high tariffs on Vietnam, China could exploit that route. So, on paper, the advantage actually lies with us (Malaysia),' he said. In 2022, Malaysia exported timber and timber products worth RM7.73 billion to the US. This was an increase from RM3.76 billion in 2018. Malaysia's timber exports worldwide include furniture, logs, veneer, plywood and medium-density fibreboard. Asked on the challenges faced by the timber industry, Wan Tarmeze said Malaysia's furniture sector primarily relies on processed wood rather than solid timber, with wood-based materials accounting for up to 85% of inputs in the making of the furniture. Wan Tarmeze said the ongoing Iran-Israel military conflict is not expected to have a direct impact on Malaysia's timber exports. Nevertheless, post-conflict reconstruction could open up new market opportunities and raise demand for Malaysian timber. 'Wars often lead to widespread destruction, but once the situation stabilises, there's usually a surge in demand for rebuilding – including homes and infrastructure,' he said. When asked how Malaysia can position itself as a high-value timber exporter rather than a volume-based player, he said the shift ultimately depends on the industry players themselves. 'This has been a long-standing conversation as Malaysia is still heavily reliant on the original equipment manufacturer (OEM) model, manufacturing timber products for others without having its own strong, internationally recognised brands. 'Take IKEA for example, which is a Swedish brand while Italy has its own well-known brand names, but Malaysia has yet to produce a brand that stands out globally,' Wan Tarmeze said. OEM refers to manufacturing products for other brands, whereas original brand manufacturers (OBM) involves developing and marketing products under one's own brand name. Wan Tarmeze said that despite the government's repeated calls for the industry to move from being OEM to OBM, the shift has yet to happen. 'The issue is not about identity but branding, and without branding we can't build value. 'The truth is Malaysia tends to shy away from copying, but we should be more open to learning from others, even 'stealing' ideas in the sense of adapting best practices and making them our own,' he said.

Malaysia forex reserves at three-year high
The country's net foreign exchange reserves rose to US$94.7bil at the end of April. KUALA LUMPUR: Malaysia's increasing currency reserves are bolstering its defences against market volatility. The country's net foreign exchange (forex) reserves rose to US$94.7bil at the end of April, according to the latest central bank data, the most since June 2022. Strong foreign inflows into local bonds and a weaker greenback, which enabled Bank Negara to unwind its net short forward forex position, both helped. These factors have strengthened the nation's bulwark against external shocks. 'The narrowing net shorts in forex forward book, combined with higher headline reserves, means that net reserves are rising at a faster pace,' said Winson Phoon, head of fixed-income research at Maybank Securities Pte, adding that Malaysia's improving external resilience 'helps support ringgit stability.' The extra buffer may be coming at a fortuitous time. US President Donald Trump's tariffs, Sino-American tensions and geopolitical uncertainty have boosted currency volatility, and a weakening of the US dollar has changed the forex dynamic for emerging markets. As a trade-dependent economy, Malaysia and its currency are particularly vulnerable to trade tensions between its two largest export destinations – the United States and China. The recent boost in foreign reserves comes partially from the US$5bil foreign inflow into the nation's conventional government securities in this quarter so far. That's on track to be the largest quarterly inflow on record in data going back to 2005. Global funds have poured in amid optimism over the outlook of the ringgit and on rate-cut wagers, as Bank Negara is the last rate-cut holdout in South-East Asia. The situation is different from December. Back then, Bank Negara's net short forward forex book had widened to US$29.2bil – just 0.2% shy of an all-time low – as the central bank utilised currency forwards to support the ringgit. — Bloomberg
