Chinese language 3D printer producer Farsoon Applied sciences is 3D printing molds to assist high-volume shoe manufacturing.
The corporate has built-in its steel 3D printing into the normal manufacturing workflow to manufacture athletic and informal footwear molds. These have reportedly been used to supply over 100 million pairs of sneakers up to now.
Farsoon started prototyping and testing its first shoe molds in 2019, which had been adopted by a “main footwear model” in 2020. The corporate’s FS350M-4 3D printer was launched to the shoe-mold market final 12 months, with its “EVA” mildew reaching industrial-scale manufacturing.
Formnext + PM South China 2023 noticed the corporate showcase its 3D printed tooling for high-volume manufacturing purposes. This included molds for vape pens/e-cigarettes. In China, 80% of those gadgets are reportedly produced utilizing 3D printed molds.
On the present, a consultant from fellow Chinese language steel 3D printer producer Brilliant Laser Applied sciences informed 3D Printing Business about its personal 3D printed shoe molds. In comparison with conventional manufacturing processes, these reportedly cut back production-cycle occasions from two weeks to 10 hours. They added that over half of typical sports activities shoe molding might be changed by additive manufacturing.
3D printing optimizes high-volume footwear manufacturing
Standard shoe manufacturing is a labor-intensive course of. It contains creating CNC wooden fashions, making silicone molds, producing plaster molds, consolidating the plaster, casting the steel molds, and making use of texturing.
In response to Farsoon, the trade is tormented by complicated manufacturing steps, labor shortages, precision necessities, and the necessity for extra eco-friendly practices. Standard strategies additionally wrestle to attain detailed texturing, stunting the precision and high quality of the ultimate product.
The corporate claims that 3D printing the molds considerably streamlines this course of, whereas digital texturing permits the exact replication of intricate patterns.
Farsoon’s steel additive manufacturing know-how reportedly enhances effectivity and accelerates manufacturing cycles, serving to to scale back prices and shorten time to market. The method contains designing the molds that are uploaded to CAD/CAM software program, 3D printed, and accomplished by way of post-processing.
This shorter manufacturing cycle is very beneficial for shoe producers who produce quite a few designs every year to maintain up with seasonal style developments.
3D printed shoe molds
Since coming into the footwear market, Farsoon Applied sciences has produced three mildew designs which might be extensively utilized in injection molding.
Its 3D printed “RB” mildew was launched in 2019. Farsoon claims that this product permits the mixing of as much as hundreds of intricate design patterns inside a single mildew, enhancing design flexibility and manufacturing effectivity. In comparison with typical manufacturing, these 3D printed molds cut back lead occasions and enhance product sturdiness by 20%.
Farsoon’s 3D “popcorn mildew” is designed to enhance the precision of shoe sole manufacturing. Every mildew options 16,000 air flow holes, every with a 0.1 mm diameter, and possesses a floor density of 95%. That is mentioned to make sure wonderful aeration whereas stopping clogging to supply footwear that’s light-weight and elastic.
The 3D printed “EVA” mildew is marketed as marking a “breakthrough” in manufacturing effectivity. Standard EVA foam mildew manufacturing includes thermoforming and cooling, with manufacturing effectivity largely depending on cooling occasions.
these molds combine conformal cooling channels, creating a superb match between the cooling channels and the mildew floor. This reportedly boosts high-production effectivity by 100%, enhancing yield and product high quality.
Farsoon’s rising shoe manufacturing ecosystem
In response to the wants of the shoe trade, Farsoon launched the quad-laser FS350M-4 3D printer together with tailored options for shoe mildew manufacturing.
With 4 500-watt fiber lasers and quick scanning speeds of as much as 10m/s, it boasts powder recoating know-how that may attain speeds as much as 400mm/s. This permits your entire powder mattress to be lined in 8 seconds, translating to 38% greater effectivity than customary recoating.
Overhang constructions can pose challenges in steel 3D printing. Farsoon’s Assist Discount System (SRS) know-how seeks to mitigate this. It reduces the necessity for helps in comparison with customary steel PBF processes, permitting elements to be 3D printed at 25° angles with none assist.
To additional deal with the fabric and utility calls for of shoe manufacturing, Farsoon performed collaborative research on materials sintering, composition, and morphology. In 2021, this work led to the event of ST1. Billed because the trade’s first 3D printable low-carbon alloy metal, the fabric is designed for steel powder mattress fusion (PBF) processes.
Not like stainless-steel, ST1 reportedly permits exact patterning, a important requirement for shoe mildew manufacturing. Farsoon has since expanded its materials processing portfolio to incorporate varied stainless-steel and aluminum alloys tailor-made for shoe mildew manufacturing. These search to deal with challenges related to extreme hardness and inadequate engraving, boosting long-term sturdiness and stability.
Extra not too long ago, in Could 2024, Farsoon launched a brand new texturing software program particularly tailor-made for shoe mildew designers. The software permits customers to assign a number of origin factors on a shoe mildew to generate custom-made textures. Designers may fine-tune algorithms to create personalised sample distributions on mildew surfaces.

The expansion of 3D printed footwear
Additive manufacturing is being more and more adopted within the manufacturing of client items, with footwear utility being no exception. Whereas Farsoon is producing shoe molds to assist million-part manufacturing runs, different firms 3D print end-use footwear merchandise in smaller volumes.
Final 12 months, sports activities tools manufacturing agency Adidas launched the MC87 4D, a limited-edition golf shoe that includes a 3D printed midsole.
Produced utilizing US 3D printer OEM Carbon’s Digital Mild Synthesis (DLS) know-how. This makes use of digital mild projection, oxygen-permeable optics, and resins to supply high-quality elements. DLS reportedly permits designers and engineers to iterate quicker, consolidate elements, and create and produce geometries not attainable with typical molding, together with software-tunable lattices.
Elsewhere, Multinational printing agency HP partnered with Brooks Operating to develop a 3D printing-enabled operating shoe. Referred to as the Exhilarate-BL, the footwear providing options 3DNA, a 3D printed midsole designed to offer a propulsive, and springy really feel.
HP’s Multi Jet Fusion (MJF) 3D printing know-how was used to manufacture the midsole, which is claimed to outperform 90% of midsoles in as we speak’s market. The sneakers had been marketed by way of a restricted launch to pick Put on Testers and Run Membership members.
On the leisure footwear facet, UAE-based 3D printed footwear startup ELASTIUM provides totally 3D printed sneakers created from 100% recyclable foam.
The lattice-structured low-density thermoplastic elastomer (TPE) foam materials is mixed with ELASTIUM’s proprietary granulate extrusion 3D printing know-how to supply the ELASTIUM-1. Designed to be snug, sturdy, and machine-washable, the corporate’s sneakers are produced on demand. This reportedly eliminates typical manufacturing bills, reduces carbon emissions, and promotes sustainability.
