01. Laser Processing
Laser processing solidifies the powder layer on the processing table. When processing is finished, the processing table is lowered and metal powder for the next layer is distributed by the distribution unit. The laser then irradiates this powder to complete the next layer. The processes 1 and 2 are repeated 10 times and then milling starts.
02. Deep ribs
Deep ribs（L/D > 17）
Thin ribs（L/D > 24）
Deep ribs and thin ribs are created with high precision by the hybrid AM process. Mold manufacture without EDM is possible.
03. 3D cooling water channels
Conventional water channels
3D water channels
Solidification within the same cooling time
Integrated cooling channels can be created internally on any component or mold. Compared to conventional post process cooling channels, these channels exhibit far superior and efficient cooling, contributing to a significant reduction in injection molding time.
Injection molding cycle time reduction by 33%
04. Time Reduction
Reduction in lead time from design to finish.
LUMEX Series can produce molds in one piece and eliminates the need for EDM, assembly or adjustment. In addition, the time required for design and CAM processing can be shortened drastically. Even with deep-ribbed molds, the design time is reduced by approx. 53%, CAM time by 90%, and manufacture time by 83%. In total, a 50% reduction in mold production time is achieved compared with conventional methods.
The outer surface of the built part is precision finished at a high speed with a ball endmill. Milling is performed when not after all layers have been completed but during build, after each preset number of layers. This hybrid, layer build process enables manufacture of parts with complicated internal structures.
08. Porous Sintering
Air permeability can be controlled freely by creating a porous structure, simply by adjusting the density of the built part. This achieves gas venting more effectively than any other machine. Users can expect the reduction of resin filling time, prevention of uneven filling, and elimination of gas burning.
11. Integrated Structures
No splitting: Create mold die parts in one.
The LUMEX Series per forms the sintering of complicated mold dies without splitting them, thus eliminating assembly and adjustment stages and making it possible to produce mold dies with no dimensional errors that may be caused by conventional assembly processes.
Back-taper shaped parts can be produced. After sintering up to layer C, the α area which is at a distance β can be finished.
14. Step Machining Process[Patent No. 4452692]
By repeating processes of “laser processing → semi-finishing → finishing”, discoloration of the finish surface as well as steps which may occur between a milled layer and a laser processed layer due to heat shrinkage can be prevented. This function is newly developed and named “Step Machining Process”. Fine finishes with high precision can be achieved.
15. Custom Made
Mesh structures can be used and designed with flexibility to match that of the surrounding bone.
16. Near-net shape
Parts that conventionally needed to be split into multiple pieces can be manufactured in one piece on the LUMEX, achieving a considerable reduction in weight. The amount of waste produced can also be reduced, which reduces environmental impact.
17. Pre-Milling Powder Suction
By removing metal powder around the built part before starting milling,a faster milling speed and a large-diameter tool can be used to shorten the milling time. At the same time, surface finish is improved with less tool wear, enabling efficient manufacture.
※For ferrous powders only
※Panasonic Corporation owns a patent regarding the “pre-milling powder suction function”.
Weight-trimming by 44% compared with conventional parts is achieved by designing the disc with a spoke-shaped mesh structure and hollow blades.
This design is possible only with additive manufacturing by laser sintering.
