"Arc Grip" type has been developed "Arc" grip type has been developed in PEEK material. so far, 3 types of grip designs are completed in PEEK material. 1. normal (taper) type 2. super grip type 3. arc type since an adequate amount of research is completed in grip section, i will move onto further developing other parts of the pen. "Super Grip" type has been developed "Super Grip" type has been developed in PEEK material 54 individual micro "protrusions" are precision-machined individually. these bulges fits between finger print ridges, enhancing anti-slip properties. different boundary lengths were tried for choosing best overall aesthetics. in the end i chose the one in the last picture. it seems quite adequate, not too excessive. in terms of performance, i.. Eureka Symmetry Model (PEEK material) new symmetry model has been successfully developed in PEEK material This is a fully precision-machined pen from solid peek rods. we only use the PEEK material imported from Germany (high quality) PEEK is a hyper-performance plastic (or super engineering plastic), that has following characteristics: 1) superb chemical resistance 2) high temperature resistance (max 260C) 3) superb strength, wear r.. ㅤ Eureka Symmetry Model developed new symmetry model has been developedMaterial: ebonite, special plastics etc.design not suitable for urushi coating (a different model will be created adequate for urushi coating in the future) below photo shows a sample of this model (unpolished state, a further polishing process will be applied) comparison to prior symmetry modeloverall thickness and length reduced(cap size reduced, below phot.. . . under normal low-lighting under bright lighting such as sun / led lamp etc. engravings: cap: butterfly barrel: butterfly . . . . eureka symmetry eureka symmetry . . . . . . . . . normal lighting hard to see details bright lighting bit of detail can be seen it will take much time for outer thick layer to clear up a bit. when urushi is exposed to lighting/sunlight outer layer becomes a bit clearer more details should be seen in the future . . under normal low-lighting under bright lighting such as sun / led lamp etc. engravings: cap: crane, cloud barrel: crane, cloud . . . . . below photo is normal lighting, engraving can't be seen under lighting some engravings may be visible it may take 1+ year(s) for the outer thick usushi layer to become clearer, then engraving will be much more easily seen below photos are under very bright lighting (like sunlight) engraved images for cap: mermaid, jellyfish, sea plants, dolphin engraved images for barrel: dolphins, sea plants re.. . 이전 1 ··· 8 9 10 11 12 13 14 ··· 24 다음
