Yog vim li cas tooj liab AM nyuaj - Thiab peb daws nws li cas

 

Ntshiab tooj liab nthuav tawm ob qhov zoo - paub txog AM cov kev sib tw: siab reflectivity ntawm infrared wavelengths thiab thermal conductivity siab heev. Kev sib xyaw ua ke ua rau tsis muaj zog nqus thiab ua kom sov sai, uas tuaj yeem ua rau porosity thiab tsis tiav fusion hauv cov pa fiber ntau -laser systems.

Peb cov kev daws teeb meem:
 
 

Ntsuab Laser (515nm):

Kev nqus tau ntau dua tooj liab, ua kom muaj kev sib raug zoo ntawm ntau dua lossis sib npaug li 99.5% (feem ntau 99.7-99.9%) thiab conductivity ntawm 95-98% IACS hauv kev tshaj tawm - lub xeev ua tiav.

 
 
 

Validated Parameter Libraries:

 Laser zog 190–500 W, scan ceev 500–1250 mm/s, txheej thickness 15–60 μm - tsim nyog nyob rau hauv lub benchmarks raws li ASTM F3301 hmoov- txaj fusion qhia.

 
 
 

Ntau- Muaj peev xwm ua tau:

 Copper LPBF (ntsuab-laser SLM/DMLS) thiab binder jetting platforms, phim rau daim ntawv thov.
