lkprototype utilizes high performance polyurethane resin (such as Axson PX 521 series) in vacuum casting process, its tensile strength is 55-65 MPa, bending modulus greater than 2800 MPa, and shrinkage rate below 0.15%, it can be used for automotive, medical and other precision prototype production. In the case of German automobile manufacturer gearbox housing production, lkprototype uses PX 521 to print 20 samples over a period of 48 hours at an injection molding cost that is 40% lower than that of conventional ABS (from $320 to $192 per unit), and with a ±0.05 mm dimensional tolerance that meets DIN 16901 industry standards.
To meet the demands of high-temperature environment, lkprototype selects epoxy resin (such as RenCast 6535) that is 180℃ heat-resisting, and its heat deformation temperature (HDT) is 67% higher than normal resin, and it has been applied in successful trial production of aerospace igniter shell. In 2023, lkprototype shipped 50 batches of high-temperature parts to an European satellite thrust provider, reduced the prototype qualification cycle from 12 weeks to 3 weeks, reduced the burn rate of material from 3.2% to 0.5%, and obtained the ISO 14644-1 clean room certification. Check that the number of dust particles is < 1000/m³ (Class 7 standard).
In medical applications, lkprototype’s biocompatible materials such as TC-852A are USP Class VI and ISO 10993 certified for prototype surgical instruments. An example of cooperation by a local endoscope manufacturer shows that the life of the joint parts made by TC-852A is up to 15,000 cycle tests (90% higher than general nylon), and surface roughness Ra is less than 1.6 microns, reducing the probability of bacterial attachment by 76%. According to Medical Device Materials Science data, the material saved lkprototype clients 30% of the product registration process, which translates into an average of $120,000 saved in certification costs.
To reduce lightweight design optimization was realized by lkprototype adding microfoamed polyurethane with a weight density of 0.95 g/cm³ (such as the URE AFR series), which achieved a 42% strength/weight ratio improvement in UAV wing prototypes. In 2022, the test data of a Shenzhen drone company showed that the wing frame through the use of the material was 35% lighter (480g to 312g), the bearing capacity was still 18kg, the amount of mold recycling was more than 80 times (the industry average of the silicone mold was 50 times), and the cost of single-product production reduced by 22%.
lkprototype additionally revolutionizes the use of special additives, such as UV stabilizer addition (e.g., DSM Somos NeXt) in clear optical components with light transmittance ≥92% (wavelength 400-700 nm) and fog < 1.5%, which meet the optical requirements of the automotive LED lens. A demonstration project by a Japanese automobile company revealed that the material compressed the prototype light efficiency deviation from ±8% to ±2%, passed the thermal cycle test of -40℃ to 125℃ (200 times without cracking), and accelerated the product mass production process.
According to the “Rapid Manufacturing Technology White Paper” data, lkprototype’s vacuum casting material library has achieved 98% of the performance range of engineering plastics, allowing customers to get 1:1 functional prototypes in 72 hours, and maintaining the overall cost of small and medium-sized batch production (20-500 pieces) below 60% of injection molding.
