3D luam ntawv ua haujlwm li cas?

3D luam ntawv ua haujlwm los ntawm kev tsim cov khoom txheej los ntawm txheej. Muaj ntau ntau 3D tshuab luam ntawv thiab lawv txhua tus sib txawv heev.

Ib qho ntawm lawv Selective Laser Sintering (SLS) ua haujlwm zoo li no:

1. Lub tshuab luam ntawv 3D nthuav tawm ib txheej ntawm cov hmoov zoo.
2. Lub laser hardens cov hmoov nyob rau hauv cov txheej txheem uas muaj cov hauv qab daim ntawm koj feem
3. Ib txheej tshiab ntawm cov hmoov zoo yog kis tawm. Cov hlais tom ntej ntawm koj ib feem yog hardened thiab koom nrog rau thawj.
4. Cov hmoov seem tseem xoob. Qhov no txhawb nqa ib feem raws li nws tau tsim
5. Qhov no tau rov ua ntau zaus kom txog thaum koj qhov chaw tsim.
6. Tom qab ntawd koj ib feem raug tshem tawm ntawm cov hmoov xoob.
7. Nws yog tom qab ntawd sandblasted thiab ua tiav los ntawm tes.

Ib qho animation thiab video (tshaj tawm: ua los ntawm lub tuam txhab kuv ua haujlwm rau) tuaj yeem pom ntawm no:

SLS yog cov txheej txheem siv los ntawm 3D Systems thiab EOS.

Fused Deposition Modeling (FDM) lwm txoj kev luam ntawv 3D tau tsim los ntawm Stratasys thiab tseem siv los ntawm RepRap project thiab Makerbot 3D printers ua haujlwm zoo li no:

1. Ib tug nyias ABS yas hlau yog extruded los ntawm lub nozzle ntawm lub taub hau luam ntawv.
2. Cov hlau yog melted thiab nteg cia nyob rau hauv lub hauv qab txheej ntawm ib tug zoo li.
3. Lub taub hau luam ntawv mus rau nws txoj haujlwm pib thiab lub platform tsim tau qis dua.
4. Ib txheej tshiab tau muab tso rau hauv thiab koj qhov chaw ua haujlwm zoo li no.

Stratasys 3D tshuab luam ntawv muaj cov khoom txhawb nqa. Qhov no yog tom qab tshem tawm thiab cia koj ua cov txheej txheem nyuaj thiab overhangs.

Stratasys 3D tshuab luam ntawv ua haujlwm zoo li no:

1. Ib tug nyias ABS yas hlau yog extruded los ntawm lub taub hau luam ntawv.
2. Cov hlau yog melted thiab nteg cia nyob rau hauv lub hauv qab txheej ntawm ib tug zoo li.
3. Lub taub hau luam ntawv mus rau nws txoj haujlwm pib thiab lub platform tsim tau qis dua.
4. Ib txheej tshiab tau muab tso rau hauv thiab koj qhov chaw ua haujlwm zoo li no.
5. Yog hais tias muaj ib qho overhanging ib feem thib ob nozzle ntawm lub taub hau luam ntawv extrudes cov khoom txhawb nqa.
6. Piv txwv li yog tias koj xav 3D luam ib tus neeg sawv ntsug. Yog tias koj tsuas yog 3D luam tawm lub caj dab koj yuav muaj teeb meem 3D luam ntawv lub puab tsaig vim tias cov khoom tsis muaj dab tsi los tsim. Nws yuav cia li mus txhua qhov chaw. Yog li dab tsi tshwm sim yog tias thaum lub sij hawm luam ntawv txhawb cov khoom yog extruded los ntawm lub thib ob nozzle thoob plaws lub cev ntawm tus neeg. Ua li no cov khoom no yog nyob rau hauv qhov chaw rau thaum koj pib luam lub overhanging qhov chaw.
7. Ib feem yog muab los ntawm lub tshuab luam ntawv 3D thiab cov khoom txhawb nqa raug tshem tawm.
