Kuchokera ku ABS kupita ku PLA kupita ku ceramic kapena zitsulo zopangidwa ndi zitsulo, apa pali mndandanda wa Zida Zaka 3D
Sayansi ya zakuthupi idzakhala yodalirika yodaliranso ndi kukwera kwa kusindikiza kwa 3D. Mukamamva za osindikiza a 3D, nthawi zambiri mumamva za kusindikizidwa mu pulasitiki, koma pali zambiri, kapena mazana, zomwe mungagwiritse ntchito mu printer 3D.
Zida Zojambula Zojambula Zachilengedwe za 3D
Zida za ABS (Acrylonitrile Butadiene Styrene):
- ABS Kutentha Kwambiri 240 ° C kapena 464 ° F
- Ndizochokera ku mafuta
- ABS imakhala ndi bedi losungunuka kapena malo omanga mkangano, pofuna kumamatira kumanga pamwamba pa njira yowakhazikika, kutanthauza kuti sichidzasuntha kapena kukwera ndi kutali ndi nsanja yomanga. Anthu ena amagwiritsa ntchito tepi ya kapton pa nsanja yotentha kuti apangidwe bwino ndikupewa kutsekemera, koma ena amagwiritsa ntchito tiketi ya pulasitiki yomwe ili yofanana ndi kapu ya Teflon.
- ABS imapanga zinthu zolimba, zolimba. Izi sizikutanthauza kuti sungathe kusweka, ikhoza, koma nthawi zambiri zimagwirizanitsidwa ndi zipangizo zina monga carbon diabetes, zomwe zimapangitsa kuti zikhale zolimba kwambiri.
- Ipezeka mu mitundu yosiyanasiyana
- ABS ingagwiritsiridwenso ntchito / kusinthidwa, granulated ndikutsitsidwanso kukhala filament kachiwiri
- ABS ikhoza kununkhiza mofanana ndi pulasitiki yosungunuka kuposa PLA ndipo zimalimbikitsidwa kuti muziyendetsa makina anu osindikizira pamalo odzaza mpweya wabwino.
Malo a PLA (Polylactic acid):
- Kutentha kwa PLA 180 ° C kapena 356 ° F
- Zapangidwa kuchokera ku magwero omwe angabwererenso, monga starch chimanga kapena nzimbe
- PLA safuna bedi lamoto
- PLA imabwera mu mitundu yosiyanasiyana, kuphatikizapo mawonekedwe omveka bwino.
- Zopangira zosindikizidwa mu PLA sizili zokhazikika kapena zolimba ngati ABS
- Ngakhale zopangidwa kuchokera ku magwero omwe angabwererenso, ndizovuta kwambiri kubwezeretsa / kubwezeretsanso kuposa ABS
Nylon (Polyamide) katundu:
- Pali mitundu yambiri ya ma nylon, kotero ndikuyang'ana Nylon 618, imodzi mwa mapulogalamu osindikizira a 3D, pakalipano.
- Nylon 618 imasungunuka pa 242 ° C kapena 464 ° F
- Sitifuna Kapape matepi, koma ali ndi zinthu zofanana kwa ABS chifukwa zimathamanga mofulumira m'mphepete mwake, zomwe zimapangitsa kuti pang'onopang'ono zisokoneze malo omanga.
- Palibe fungo loopsa pamene limasindikizidwa pa kutentha kwabwino, komabe tikulimbikitsidwa kuti tigwiritse ntchito m'dera lopuma mpweya wabwino.
- Wamphamvu kuposa ABS kapena PLA
- Amapereka malo otsekemera ngati mukulumikiza ziwalo kapena makola omwe amafunika kusinthasintha mosavuta
Metal 3D Printing Powders
Ndi zitsulo zambiri zomwe zimakhala ndi zowonjezera zoposa 500 C kapena 1,000 F, mukhoza kuona chifukwa chake zitsulo zosindikiza 3D zimakhala zodula, ndipo zingakhale zoopsa, ngati zisagwiritsidwe bwino. The American Society for Testing and Materials (ASTM) imadziwika bwino ndipo imapereka miyezo ku chitetezo ndi khalidwe. Iwo posachedwapa anamasulira imodzi yokhala ndi zowonjezera, makamaka kwa zitsulo zamkuwa, kuti mukhoza kukopera (kulipiritsa) kapena kuwerenga pang'ono za izo apa.
Metal powders ndi okwera mtengo kwambiri. Zina mwa ufa wamba zomwe ndaziwona kapena kuziwerenga ziphatikizapo:
- Metal alloys
- Titani zilembo
- Cobalt Chrome alloys
- Chitsulo chosapanga dzimbiri
- Aluminium
Ceramic ndi Galasi Zojambula Zithunzi za 3D
Sculpteo, malo osindikizira osindikizira a 3D, amajambula mu ceramic ndi printer Z Corp 3D.
Shapeways yatsala pang'ono kuzimitsa zojambulajambulazo ndi kuyika mapepala okongoletsera 3D, monga zinthu zatsopano. Zikuwoneka zokongola kwambiri ndipo mukhoza kuwerenga za izi apa.
Kusindikiza kwa 3D ndi Zakudya
Pali anthu omwe akuwongolera makina awo osindikiza a 3D osindikizira kuti asindikize ndi chokoleti, ndi broccoli, ndi chisakanizo cha keke, kutchula ochepa chabe. Sindinakayikebe kuti zina mwa izi zidzalawa zabwino, koma ndine wotseguka kuyesa ...
Kufufuza nkhani zamakono zojambula za 3D kapena zolemba
Ndipitiriza kuwonjezera pa zolemba zowonjezera zowonjezera ma polima atsopano, masitimu atsopano, zitsulo zamatabwa, zowonjezera ndi galasi, ndi chirichonse chomwe chatsopano chinagulitsidwa ku msika wosindikizira wa 3D. Monga ndatchulira mndandanda wina, makampani monga Proto-pasta, akupanga mitundu yosiyanasiyana ya ma polima, kuphatikiza zipangizo zatsopano ndi ABS kapena PLA kuti apange chipangizo chatsopano.
Kambiranani ngati muli ndi zinthu zomwe ndikuyenera kuzilemba pano: Mutu ku tsamba langa la Bio komwe ndimasunga zonse zanga.
