Yuav Ua Li Cas 3D Sau Nrog Polypropylene PP Khoom Siv?

Polypropylene (PP) yog qhov tseeb ib qho ntawm cov polymers tshaj plaws hauv lub neej txhua hnub. Nws muaj cov nyhuv translucent thiab zoo heev tshuaj lom neeg thiab qaug zog; ua ke nrog zaub mov thiab microwave kev nyab xeeb, nws feem ntau yog siv hauv cov thawv ntim hauv tsev.

Polypropylene (PP) yog qhov tseeb ib qho ntawm cov polymers tshaj plaws hauv lub neej txhua hnub

Thiab rau 3D luam ntawv, PP yog qhov tsim nyog rau ua txhua yam uas yog lub teeb yuag, tsis muaj dej lossis siv tau ntev. Piv txwv li, cov hinges sawv cev rau ib qho kev siv ntau heev vim tias PP tuaj yeem hloov kho dua ib zaug yam tsis muaj kev tawg. PP txoj kev coj ruaj khov ua rau nws yog cov khoom kom zoo saib, tab sis nws paub zoo tias nws nyuaj rau kev los tswj thaum thov 3D luam ntawv. Cia peb saib cov kev sib tw ntawm cov khoom no thiab ob peb txoj hauv kev los daws lawv.

Warpage tshwm sim los ntawm tshav kub tsis sib haum

Cov teeb meem tseem ceeb nrog polypropylene yog nws cov adhesion tsis zoo. Txawm hais tias qhov no yuav zoo rau qee txoj kev ua, nws tsis zoo rau cov txheej txheem 3D luam ntawv. Qhov no tuaj yeem ua rau nws nyuaj rau luam tawm los txuas rau ntawm cov ntawv luam tawm thiab ua rau ntog poob.

Ib qho kev sib tw ntxiv rau yog cov polypropylene muaj cov qauv ua ib nrab. Thaum lub caij 3D luam ntawv, qhov no txhais tau tias kev kub ntxhov siab ntawm kev kub ntxhov yog tsim tawm, uas tuaj yeem ua rau thawj txheej txheej uas daig rau cov ntawv luam tawm kom pom tag nrho. Txij li sau luam tawm txaj ua haujlwm thiab kev tawm tsam yog qhov teeb meem tseem ceeb uas peb ntsib, qhov no tseem yog qhov kev sib tw uas cov neeg lag luam xav kom daws kom ua tiav 3D luam tawm nrog polypropylene.

1. Khaws cov kab xev ntim pob tshab rau ntawm daim ntawv luam ntawv

Cov kab xev feem ntau yog siv los ua cov khoom pab adhesion ntawm cov txaj luam ntawv. Kapton daim kab xev thiab kab xev xiav 3M yog cov kev xaiv ntau. Hmoov tsis zoo, cov kev xaiv classic no tsis ua haujlwm zoo thaum siv PP cov ntaub ntawv vim PP tsis ua zoo rau ntau yam ntaub ntawv.

Zoo hmoo, feem ntau pob tshab ntim khoom ntim tau ua ntawm polypropylene. Yog li no, qhov no yog qhov tawm tsam-kev txiav txim zoo. Koj tuaj yeem sim luam ntawv ntawm pob tshab ntim cov ntaub nplaum. Txawm hais tias qhov saum npoo ntawm cov kab xev no tau yooj yim me ntsis, nws tuaj yeem ua rau tib cov ntaub ntawv PP yooj yim dua rau nws. Cov.

2. Siv tus ntsuas loj dua

Txhawm rau tiv thaiv qhov kev kub ntxhov siab ntawm kev ua siab tawv ntawm polypropylene, lub hauv paus loj dua yog qhov xav tau, uas yuav ua rau thaj tsam thaj chaw ntawm thawj txheej tau luam tawm, txo qhov kev xav ntawm qhov kev xav ntawm warpage kev nyuab siab, thiab nce qhov tshwm sim ntawm kev luam ntawv zoo. Nws tsuas yog xav tau tev tawm tom qab luam ntawv, thiab nws yuav luag tsis muaj qhov cuam tshuam sab nrauv ntawm daim qauv. Thaum siv PP, nws yuav tsim nyog los nce qhov loj me ntawm lub hauv paus phaj tshaj li lwm yam khoom siv.

3. Ua kom qhov kub zoo dua

Tsa lub txaj kub kom txo tau warpage thiab qhov chaw poob

Lwm txoj hauv kev los txo cov warpage yog ua kom lub txaj kub. Qhov no tuaj yeem tiv thaiv PP los ntawm kev ua kom txias ntau dhau, yog li txo tus nqi shrinkage. Los ntawm kev txo qhov shrinkage, qhov nyiaj ntawm kev ua rau kev ntxhov siab tsim tawm tuaj yeem raug txo kom tsawg. Qhov pib zoo yog PP pib teeb tsa rau lub tshuab luam ntawv los yog chaw tsim tshuaj paus, yog tias muaj kev pom zoo kev teeb tsa. Txwv tsis pub, pib ntawm 85 ° C thiab maj mam nce lub txaj kub ntawm 5 ° C kom txog thaum koj pom qhov ntsuas kub zoo-nws yuav tsum nyob nruab nrab ntawm 85 txog 100 ° C.

Nws kuj tseem muaj txiaj ntsig zoo rau kaw lub tshuab luam ntawv 3D kom ua kom kub thiab tiv thaiv kom tsis txhob muaj qhov kub hloov pauv. Yog tias koj xav tau zoo dua 3D cov ntawv luam tawm, koj tuaj yeem sim ua 3D tshuab luam ntawv lub hau kaw koj tus kheej, xws li cov khoom siv acrylic.

Luam tawm PP cov ntaub ntawv nrog Prusa 3D tshuab luam ntawv

Txij li PP cov ntaub ntawv tsis zoo li ntawd hauv 3D daim ntawv thov kev luam ntawv, nws nyuaj rau nrhiav cov kev daws qhov tseeb; tab sis cov khoom siv raw PP nws tus kheej yog ib qho ntawm cov plastics feem ntau siv, yog li nws yog qhov yuav tsum tau sim ntau ntxiv thaum lub sij hawm luam ntawv txhawm rau kom tau txais qhov zoo tagnrho Cov Luam Tawm.
