Best answer: Yes! Properly washing and curing resin 3D prints is crucial, and the Anycubic Wash and Cure V2 is an inexpensive way to handle the messy reality of resin 3D printing. With a 3.5l Isopropyl Alcohol tank and a UV turntable, it takes a lot of the fuss out of resin post-processing.
Filament 3D printed miniatures don't need to be washed, but you should clean up any excess plastic. For resin 3D printed minis, you want to wash them as part of your normal post-processing, either with isopropyl alcohol or soap & water for water washable resin. Use a wash & cure station or an ultrasonic cleaner.
After calibrating your resin printer you may need up to 8 hours per print and you may be able to print only 4 models at a time, sometimes even less. Some resin printers can do this in less time, say 2-4 hours. But a rule of thumb is that the greater the quality of the print, the longer it will take on a resin printer.
Resin can be reused, but be careful when putting it back into the original bottle if you want to avoid cross-contamination. Sadly, it can't be melted and reused again like you with a filament extruder!
Fully hardened and cured resin can be safely disposed of. In the case of structural supports made by the printer during the build, these can be simply thrown away. However, if excess hardened or semi-cured resin leftover can't be reused, it must be handled with care.
Most newer epoxy resins, which contain less epichlorohydrin, do not seem to cause cancer in animals. Diaminodiphenyl sulfone (DDS), a curing agent in some epoxy resin systems, is carcinogenic in laboratory animals. Certain glycidyl ethers used in epoxy products cause genetic mutations in laboratory animals.
Working with or exposure to certain epoxies or resins could increase your chances of having fertility problems, miscarriage, stillbirth, or a baby with birth defects. Here, you can learn more about these chemicals and what you can do to reduce your exposure for a healthier pregnancy.
Prolonged breathing of highly concentrated epoxy vapors can cause respiratory irritation so wear a respirator mask to be safe!
Paper, plastic, fabric, metal, clay, wood, natural elements, glitters and powders, and any combination of these elements work well. Things that contain moisture should be avoided, for example, fresh flowers and leaves. The water will react with the resin, turning the leaves and petals brown.
Repeated skin contact with resins and hardeners may also cause chronic contact dermatitis, which is usually milder but longer lasting. If left untreated for long periods it can progress to eczema, a form of dermatitis that can include swelling, blisters, and itching.

Injection molding is cheaper than 3D printing if you produce more than 100 parts. While the cost per unit using 3D printing stays relatively unchanged, the price for injection molding becomes dramatically better the more pieces you manufacture with your mold.
If a 3D printed prototype is rather complex and/or requires assembly, test fitting, and possible design adjustments, then the cost range would typically go up to $1,500 – $12,000. An example of such a prototype could be a simple electrical device or a mechanism with a few moving parts.
Molds are generally made from steel or aluminum and are precision-machined to form their specific features. A liquid material is fed into a heated barrel, mixed, and fed into the mold's cavity, eventually cooling and hardening to the mold's configuration.
Plasticization occurs when the screw rotates to move material through the 3 zones; feed zone, compression zone, and metering zone. After moving through the metering zone the material passes through the check ring into the shot where it will be ready to inject into the mold.
T-Molding (a.k.a. Expansion Molding)T-moldings are typically used in doorways without thresholds (with the same flooring on each side of the doorway) or in L-shaped rooms or hallways, when you want to change the direction of the planks.
In general, five steps are involved in the RP process, as shown in Figure 14.1. They are CAD solid modeling, model conversion to STL, STL model slicing, model fabrication, and post-processing, resulting in a physical prototype.
Rapid prototyping is an agile strategy used throughout the product development process. With this approach, 3-dimensional prototypes of a product or feature are created and tested to optimize characteristics like shape, size, and overall usability.
Begin on day one of your period and count the number of days until your next period, which is day one of your next cycle. Track for 3 months and add the total number of days. Divide that number by three and you'll have your average cycle length.
The three main routes are intradermal (ID) injection, subcutaneous (SC) injection and intramuscular (IM) injection. Each type targets a different skin layer: Subcutaneous injections are administered in the fat layer, underneath the skin. Intramuscular injections are delivered into the muscle.

Indoors, use curtains or blinds to hide valuables. Don't leave electronics, jewelry, cash, or important personal documents in plain sight. For your most valuable items, you can lock them away in a safe. Another tip is to be discreet when you purchase a new valuable item.
Home protection and family safety are the primary purposes of a home security system. While this includes detecting burglary, a security system also detects a number of other threats, including smoke, fire, carbon monoxide poisoning, and water damage.
There are four main types of security: debt securities, equity securities, derivative securities, and hybrid securities, which are a combination of debt and equity.
A CCTV camera system makes use of video cameras, also called surveillance cameras to keep track of the interior and exterior of a property, transmit the signal to a monitor or set of monitors, and give real-time 24/7 viewing access.
security and protection system, any of various means or devices designed to guard persons and property against a broad range of hazards, including crime, fire, accidents, espionage, sabotage, subversion, and attack.
There are four basic types of panels: coded panels, conventional panels, addressable panels, and multiplex systems.
There are three main types of fire alarm monitoring systems: ionization, photoelectric, and combination alarms. Below we will discuss each type of alarm and how they can help detect fires.
As the name suggests, a wired or hardwired home security system relies on wires running through your house to send information back to the central control panel, triggering alarms or notifications when appropriate and notifying your security company if that is part of your service package.
Not only is having a bunch of flyers or stickers stuck in your door a nuisance, it can also serve as a way for burglars to mark your home. Many burglars will stick flyers or stickers on homes that they think are unoccupied to serve as an indicator for their accomplices that the home is unguarded.

堅持辦學正確政治方向 建設中國特色世界一流大學
——習近平總書記的考察在北大引起熱烈反響
5月2日的北大燕園,湖光塔影,綠樹婆娑,隨處可見的校慶標識,讓美麗的燕園激情蕩漾,暖意融融。
在五四青年節和北京大學120周年校慶日即將到來之際,中共中央總書記、國家主席、中央軍委主席習近平來到北京大學考察並發表重要講話。“習近平總書記來校考察調研並發表重要講話,充分體現了對教育工作者和青年學生的親切關懷,令全校師生備受鼓舞、倍感振奮。”北京大學黨委書記郝平說,習近平總書記一直高度重視北大的發展,2007年以來,他先後六次蒞臨北大,兩次給北大師生回信。2014年5月4日,習近平總書記在北大考察時,提出了“人生的扣子從一開始就要扣好”“紮根中國大地辦大學”等重要思想,為我國高等教育發展提供了根本遵循。
堅持辦學正確政治方向 建設中國特色世界一流大學

2018年5月2日,總書記再次來到北大,明確指出,辦出中國特色世界一流大學、培養社會主義合格建設者和接班人,要抓好三項基礎性工作。對於北大師生及至北大曆史來說,這無疑又將是意義非凡的印記——
牢牢抓住培養社會主義建設者和接班人這個根本任務
習近平總書記要求,堅持辦學正確政治方向。
郝平深有感觸,他說:“習近平總書記的重要講話具有極其豐富的思想內涵,意義重大、影響深遠,闡明了新時代中國高等教育的奮鬥方向與發展路徑,針對性、指導性很強。”
總書記指出,我國社會主義教育就是要培養社會主義建設者和接班人。馬克思主義是我們立黨立國的根本指導思想,也是我國大學最鮮亮的底色。要抓好馬克思主義理論教育,深化學生對馬克思主義曆史必然性和科學真理性、理論意義和現實意義的認識,教育他們學會運用馬克思主義立場觀點方法觀察世界、分析世界,真正搞懂面臨的時代課題,深刻把握世界發展走向,認清中國和世界發展大勢,讓學生深刻感悟馬克思主義真理力量,為學生成長成才打下科學思想基礎。要堅持不懈培育和弘揚社會主義核心價值觀,引導廣大師生做社會主義核心價值觀的堅定信仰者、積極傳播者、模范踐行者。要把中國特色社會主義道路自信、理論自信、制度自信、文化自信轉化為辦好中國特色世界一流大學的自信。
北京大學校長林建華表示,認真學習貫徹習近平總書記重要講話精神,建設高等教育強國,必須牢牢抓住培養社會主義建設者和接班人這個根本任務,堅持辦學正確政治方向,建設高素質教師隊伍,形成高水平人才培養體系,努力建設中國特色世界一流大學。必須抓住國家發展機遇,以更加開放的姿態,兼收並蓄、守正創新、引領未來,聚焦學術發展的最前沿,建立中國視角的人文社會科學體系,建立符合國情的科技成果轉化體系,不斷產生出新知識、新思想、前沿科學和未來技術,為國家發展提供更有力的支撐。
北京大學中國語言文學系教授、習近平新時代中國特色社會主義思想研究院副院長韓毓海說,中國人有著獨特的精神世界,這種精神世界的凝聚就是社會主義核心價值觀,而社會主義核心價值觀就是我們辦學的初心。社會主義核心價值觀,承載著一個國家、一個民族的精神追求,體現著一個社會評判是非曲直的價值標准。以社會主義核心價值觀為指導,就是要求我們明確辦學的初心,是為中國、為人民做學問。
作為北大教師和基層黨委書記代表,經濟學院黨委書記、教授董志勇在現場聆聽了習近平總書記的重要講話。他說,在曆史上,北大的教師群體與中國共產黨的建立和發展息息相關,與馬克思主義在中國的傳播淵源相連。這是北大教師永遠的驕傲,也是進一步抓好教師思想政治建設的強大精神動力和重要傳統資源。
得天下英才而育之,既是榮耀也是責任
習近平總書記要求,建設高素質教師隊伍。
總書記說,建設政治素質過硬、業務能力精湛、育人水平高超的高素質教師隊伍是大學建設的基礎性工作。要從培養社會主義建設者和接班人的高度,考慮大學師資隊伍的素質要求、人員構成、培訓體系等。要堅持教育者先受教育,讓教師更好擔當起學生健康成長指導者和引路人的責任。要抓好師德師風建設,引導教師把教書育人和自我修養結合起來,做到以德立身、以德立學、以德施教。
董志勇說,作為北大教師,我們要不斷提高自己的思想政治素質,以正確的理論引領學生;要不斷提高業務素質,以豐富的專業知識培育學生;要不斷強化教師職業道德建設和科學精神培養,以高尚的情操感染學生,愛生奉獻,教書育人。他說,對北大教師而言,得天下英才而育之,既是一個榮耀,也是一個責任。“如何讓北大學生成為一流畢業生,是我們肩上沉甸甸的責任。我們希望學生帶著獨立、求真的精神來到北大學習,全方面培養自己的生存能力、適應能力和自我發展能力。我們希望學生成為‘基礎厚、視野寬、素質高、能力強、修養好’的優秀畢業生,成為情商優秀、智商超群、勇於創新、敢於擔當的北大人。”
“為了更好地完成習近平總書記提出的目標和要求,我們需要增強北大的核心競爭力。在我看來,核心競爭力不僅包括北大的優良傳統和北大精神,還包括我們的教師和學生。可以說,北大的教師是一流的,作為院系領導,我們要為一線教師做好服務,讓他們發揮更大的作用。”北京大學法學院黨委書記、教授潘劍鋒說。
韓毓海說,座談會上,心理與認知科學學院本科生宋璽的發言讓人特別感動,催人淚下,讓我們真切體會到當代大學生是可愛、可信、可貴、可為的。“知者行之始,行者知之成。我們的思政教育就是要讓同學們全面客觀認識當代中國,認識到中華民族偉大複興是不可阻擋的曆史潮流。在馬克思主義中國化的偉大實踐中,加深對習近平新時代中國特色社會主義思想的理解。”
不辱使命,青年要成為實幹家
習近平總書記要求,形成高水平人才培養體系。
總書記指出,人才培養體系涉及學科體系、教學體系、教材體系、管理體系等,而貫通其中的是思想政治工作體系。加強黨的領導和黨的建設,加強思想政治工作體系建設,是形成高水平人才培養體系的重要內容。要堅持黨對高校的領導,堅持社會主義辦學方向,把我們的特色和優勢有效轉化為培養社會主義建設者和接班人的能力。要下大氣力組建交叉學科群和強有力的科技攻關團隊,加強學科之間協同創新,加強對原創性、系統性、引領性研究的支持。要培養造就一大批具有國際水平的戰略科技人才、科技領軍人才、青年科技人才和高水平創新團隊,力爭實現前瞻性基礎研究、引領性原創成果的重大突破。
習近平總書記冀望青年,每一個青年都應該成為社會主義建設者和接班人,不辱時代使命,不負人民期望。
宋璽說:“我在大三當兵以前,幾乎過著四體不勤、五穀不分、無憂無慮的大學生活。在這樣安逸的環境下,人容易變得空虛。當時我就意識到,不能就這么過下去,因此我選擇到部隊去,到基層部隊去。從蜜罐子到部隊,我深刻感受到,大學生不能脫離群眾,不能架空自己,一旦如此,就沒辦法真正理解什么是馬克思主義,什么是社會主義。”
經濟學院博士生、第二十六屆全國學聯主席王聖博一直在思考,在中華民族偉大複興的征程中,自己應該扮演什么樣的角色,作出什么樣的貢獻。“我們這一代北大人,很多都對國家曾經的苦難輝煌缺乏感同身受的認識,這為我們凝聚人心的工作增加了難度。對於北大學子思想上的新問題新現象,我們應該反思,不應該回避。我們這些學生幹部在強調服務的同時,要做好思想引領,更要身體力行。通過真學、真信、真用,感召身邊的同學們。”
教育學院碩士研究生李曉丹說,習近平總書記的重要講話讓我們認識到,我們這一代人將經曆社會主義現代化建設的整個過程,這既是一種榮譽,也是極大的鞭策。在未來,我們要以更大的奉獻精神,努力成為實幹家,在新時代幹出一番事業。
郝平最後說,北大師生在歡送總書記時再次喊出了“團結起來、振興中華”的口號,體現出青年學子對總書記重要講話的高度認同和堅決擁護,這是新時代青年的心聲,是凝心聚力的中國好聲音。北京大學黨委第一時間召開了理論學習中心組擴大會議和師生代表座談會,將深入開展學習貫徹習近平總書記重要講話精神的系列活動,把總書記的重要講話精神傳達給每一位老師、每一位學生,切實把總書記的重要講話精神作為辦學工作的指導思想,努力貫徹落實到學校工作的各個方面。
