What Does Meka Stand For
This article will give you a quick overview of the current consumables used in 3D printing and will explain the main differences in terms easily understood by beginners. As explained in our previous article “What is 3D printing?”, there are mainly two sorts of 3D printers, the industrial-type printers and the consumer-oriented 3D printers, a.k.a.
Desktop 3D printers.More.The present article will only focus on the most common consumables used in consumer 3D printers using the (fused deposition modeling) technology. A traditional inkjet printer needs ink cartridges in order to be able to print – the situation is similar for 3D printers, except that 3D desktop-type printers need plastic filament. These consumables are mostly available online in a variety of types of material (, etc.), colors, diameters and lengths.What you will learn. The Pros and Cons of ABS, PLA and PVA. The specific uses of each filament type.
The recommended extrusion temperatures for each material. Where to buy ABS, PLA and PVAWhat Material? – ABS vs PLA vs PVANote: the more exotic printing plastics like polycarbonate (PC), high-density polyethylene (HDPE) or nylon are not discussed in this article.
ABS (Acrylonitrile Butadiene Styrene)is used in a very large variety of applications in the industry nowadays. Examples include, among many others, the manufacturing of pipes (like drain, waste or vent pipes), automotive components, electronic assemblies, protective headgear (ABS has good shock absorbing properties), kitchen appliances, music instruments, protective carrying cases and toys, among which the most notable are the famous Lego bricks. The famous Lego bricks - made from ABSABS is generally very durable and strong, slightly flexible and quite resistant to heat. 3D printers able to process ABS plastics normally operate with a (the heated part melting the plastic, before it’s forced through the print ) at a temperature around 210-250°C.
Therefore, a 3D printer able to process ABS is necessarily equipped with a heated, in order to prevent warping or cracking of the printed materials.When it comes to cost, ABS is the cheapest plastic of the three filament types analysed and until recently was the favourite material of the 3D printing community. The material is suitable for a very large variety of purposes, especially as it can easily be sanded (to smooth the printed objects and remove jagged edges) and painted. Printed or broken parts can simply be glued together with ABS glue and it is easily soluble in acetone (i.e. Nail polish remover). ABS is generally available in white, black, red, blue yellow and green colors or transparent and has a matte appearance. ABS filament spools - various colors: natural, silver and blueBut ABS also has some drawbacks.
First of all, it is a petroleum-based non-biodegradable plastic, that can be recycled though. Another problem is that ABS does create (mild) fumes which may irritate more sensitive persons – an installation of the printer in a well ventilated area or even a specific fume hood may be necessary. More recently, have been hitting the market. ABS can also deteriorate by prolonged exposure to sunlight.If you are not using your ABS spool over a longer time, you should store it properly in an airtight container. ABS does attract moisture from the ambient air, which may affect your prints.
If you are looking for tips on how to store 3D printer filament, check out.PLA (Polylactic Acid)is a biodegradable which is derived from renewable resources, such as cornstarch, sugar cane, tapioca roots or even potato starch. This makes of PLA the most environmentally friendly solution in the domain of 3D printing, compared to all the other petrochemical-based plastics like ABS or PVA. PLA is used for example in medical suturing as well as surgical implants, as it possesses the ability to degrade into inoffensive lactic acid in the body. Surgically implanted screws, pins, rods or mesh simply break down in the body within 6 months to 2 years.But, PLA is also used in food packaging, bags, disposable tableware, upholstery, disposable garments, hygiene products and even diapers. PLA is therefore considered as pretty safe.
For those wanting to print PLA drinking cups or other recipients destined for food or drink, a word of caution though: do not forget that the coloring pigments in the filament may not be as harmless as the PLA itself. Unfortunately, the notice of use nearly never documents the chemical composition of those pigments in order to inform about their harmlessness or potential toxicity. Various 3D prints, all printed in PLAPLA is tough, but a little brittle, once it has cooled down. Its temperature threshold is lower than the one of ABS, as PLA is normally extruded around 160°C-220°C. A heated printbed is not mandatory, but it may (at temperatures around 50-60°C) be beneficial to the quality of the printed object.
PLA is quite slow to cool – experts recommend sometimes to install a fan pointed at the extruded material in order to speed up the cooling process. Once it is heated, PLA does emit a slight odor, best described as sweet corn, pancakes or maple syrup – but it does not emit fumes like heated ABS. No fume hood will be necessary and you may safely print with PLA in-house.PLA can be sanded down and may be painted over with acrylic paint, but some people recommend using a primer. Glueing PLA is however not as easy as glueing ABS. Most people seem to get some results with cyanoacrylate (i.e. Super glue), but this does have some disadvantages of its own (use of safety glasses and gloves, extreme stickiness to fingers and other body parts, very quick, etc.).PLA has become a very popular choice in the 3D printing community, considering its low toxicity and its better environmental friendliness, compared to all the petroleum-based plastics.
Its main drawbacks are that it cannot stand too much heat, as standard PLA becomes soft around 50°C (i.e. You can re-heat your printed object with a hot air gun, for example). On the other hand, one may consider this an advantage in order to easily repair, bend or weld printed parts. PLA filament comes in a great variety of colors.

It has been becoming more and more readily available and probably will overtake ABS as the preferred material choice. PLA is available in most colors and may be translucent or solid. When it comes to colors, gives you a pretty good idea what is currently available. Most notable colors are the translucent (a.k.a. Transparent) one, as well as the “glow in the dark” PLA. Soft PLA is also available – this very interesting variant permits the printing of flexible materials, but is more complicated to use.
Sourcing soft PLA may also prove difficult.As with ABS, PLA does also attract water molecules from the air. PLA is more prone to water absorption than ABS and it will become (more) brittle and sometimes difficult to print with,as water saturated PLA needs a higher extrusion temperature. If you want to read more about how to counter this phenomenon, read our article on.PVA (Polyvinyl Alcohol)is a special plastic that is water-soluble. It is most commonly used as paper adhesive, as thickener, as packaging film, in feminine hygiene and adult incontinence products, as mold release agent or in children’s play putty or slime. Another wide use is in freshwater sport fishing, where PVA bags filled with bait are thrown into the water. The bag rapidly dissolves, releasing the bait, in order to attract the fish.In 3D printing, PVA is sometimes used in printers with dual or multiple-extruders, in order to provide a support structure to an object with issues. Some complex prints involving lots of overhangs (areas where there is no support under the upper layers) can be realized only by printing such a support structure.
Otherwise, the printed structure would warp or simply collapse. The finished object can be put into water until the PVA has completely dissolved, freeing the object of the support structure, without the need of any pesky manual post-printing. The final result: the PVA is completely gone.

PVA needs to be stored in a sealed box or container together with a desiccant and may need to be dried before use. Another disadvantages of PVA include its high price and quite difficult sourcing.Filament Diameter and Filament SourcesOnce you have chosen the appropriate material, you should check whether the filament diameter is compatible with your printer before ordering. The two standard diameter sizes for filament are 1.75mm or 3mm. Only some printer models can accept both of these and you should always check what diameter your printer can use.Filament is generally sold at its weight price. Spools of 750gr, 1kg or 2,5kg are standard sizes, although some materials are sold by the meter or in loose coils (especially the more exotic filament colors or plastic types).
When it comes to quality, some people argue to only buy from reputable suppliers, but these filaments may come with a certain price tag. Others have had good experience with relatively cheap filament. In the end, it comes down to experimenting with filaments from various sources, before finding the one suiting your needs best. In case you are interested to buy any of the filaments described above, we can recommend the following sources.
StrategyD.Va is a unique tank with some mobility. With very high health and Boosters, she can close a gap to the enemy with ease. She has high damage output at close-range, making her a strong fighter in a 1-on-1 match.
Her Defense Matrix is useful against all incoming projectiles, protecting her teammates from enemy fire. The Micro Missiles deal high amount of damage when used in close range. She is a dangerous ganker in tank class, dealing consistent damage to the enemy. Self-Destruct will wipe all opponents within the blast area. However, she doesn't have an extended barrier to properly protect her team like Reinhardt. She is also slow while firing, allowing the enemy to outrun her to disengage or move around her to distract her aiming.
Both Fusion Cannons and Micro Missiles are ineffective at anything further than medium-range, meaning she can be outranged by the enemy before she even has a chance to close a gap with Boosters.Weapons & Abilities.: D.Va's main weapons on the mech. Her mech can fire consistent shotgun-like bullets onto the targeted point.
D.Va is a former professional gamer who now uses her skills to pilot a state-of-the-art in defense of her. She is a very competitive individual, and coupled with her pro-gamer skills, this makes her an extremely effective mech pilot. Never backing down,D.Va always plays to win. While she projects a carefree, irreverant attitude, D.Va is burdened by the emotional cost of defending her homeland, and the facade the South Korean media projects on her.In addition to skills as a mech pilot, D.Va is also a competent mechanic. Early Life “It's like how we used to stay up late, and work on your hoverbike.You mean the one you wrecked?Really? You're still mad about that? We won the race!Yeah!
And you almost killed yourself!„ Dae-hyun and Hana. Song on the e-sports sceneHana Song grew up playing classic games with her father, himself a former professional gamer during his younger years. He was the one that introduced her to, and her undeniable skill helped lay the foundation for her eventual e-sports victories in other games.Song has been friends with since childhood. They would stay up late working on his.
Hana took part in a race with it and won, albiet at the cost of the bike and nearly her own life.Like her father before her, Song became a pro-gamer. She became a player in high school, quickly ascending to the #1 rank, winning the world championship, surpassing her teammate and rival. A fierce competitor, Song played to win at any cost, and gained a well-earned reputation for showing no mercy to her opponents. Song pilots her mechAt home, however, not all was well, as struggled to maintain its defense against the that repeatedly attacked the nation. As the omnics continued to adapt, they eventually disrupted MEKA's drone-control networks, forcing the military to place pilots in the mechs. Scrambling to find suitable candidates, the government turned to the country's professional gamers, who possessed the necessary reflexes and instincts to operate the mechs' advanced weapons systems, in addition to standouts from other fields that required similar talents. Top stars were drafted, including the 19-year-old Song, along with Lee and Kyung-soo.
She saw the new mission as a game, and an evolution of her own career. Without fear or hesitation, she abandoned the limelight of her pro-gamer career, and got an armored mech operator's licence. As a member of MEKA, she could put her reflexes to the ultimate test on a real battlefield, instead of a digital one.
Her skills and intense competitive spirit made her an extremely effective pilot. A MEKA poster of D.VaSong now fearlessly charges into battle alongside the rest of her MEKA unit, ready to spring to her nation's defense at a moment's notice. Recently, she has begun to stream combat operations to her adoring fans, and her growing following has turned her into a global icon. Sponsorship deals and her fanbase provided her with the means to customize her mech, such as.At some point she also played one of the leading roles in the movie.As an active member of the military, Song was no longer able to freely travel as she could've as a civilian.
She became an avid reader of Mei's Adventures, the publicly-posted travel journal of climatologist, fascinated with all the different places Mei has seen. Shooting Star “Oh man. This time off is great, isn't it?What's not to like? There's delicious food, and drinks.Yeah.And good friends.
The kind that are always there for you- when you need them most.„ Dae-hyun and Song after the Gwishin attack. D.Va reflects on her burdenAs time went on, the cost of defending South Korea from the Gwishin began to take its toll on Song. In one battle in Busan during a thunder storm, the squad barely managed to defeat the omnics, but the other mechs were put out of commision due to serious damage and their pilots sustained some injuries; only Song came out of it relatively unscathed. While the rest of the squad went on leave and the media reporting that Song was celebrating the victory by schmoozing with celebrities, Song had actually chosen to remain on active duty and spent time over the next week fixing and fine-tuning her mech alongside Dae-hyun, who had also joined MEKA as her assigned mechanic. As she stated that the squad and the rest of Busan were counting on her to keep the city safe, and any mistakes on her part could cost them everything, Dae-hyun recognized the emotional weight Song was carrying.
He tried to convince her that she needed a break and that it was okay to ask for help, not needing to bear it alone, but she assured him that she had things under control. Ready to launchThat didn't last long however, as five Gwishin omnics returned to attack Busan—while previous attacks were spaced between months, this one was just one week, which left the pair the only ones present to defend against the omnics. Song launched her mech to engage them.
She took out two of the Gwishin, but the remaining three outmaneuvered her, damaging her mech and destroying one of the fusion cannons. Dae-hyun told her to get to cover and wait for reinforcements, but Song stated that they wouldn't get there in time. Performing a 180 on the pursuing omnics, she managed to destroy two of them, while the last Gwishin broke off and headed for Busan. Song pursued it, but it avoided her weapons fire and micro missile barrage before turning around and entangled her mech, tearing off the other cannon when she tried to fire on it.
Left without any weapons, all her status readouts in the redline, and the city still in danger, she realized she could do nothing else and asked for her friend's help.With Dae-hyun going over the mech's status, on the mention of the reactor becoming unstable Song remembered their earlier conversation of the destruction of his hovercycle, and suggested purposely overloading the mech's reactor. After some protest, Dae-hyun obliged, and as Song distracted the omnic to buy him some time he successfully triggered an overload that would destroy the reactor in sixty seconds. The omnic would reach Busan before that however, so Song ejected from the mech and used her to shoot the reactor from afar, destroying both the mech and the omnic.
She fell into the sea, where she was recovered by a search-and-rescue team and taken for medical treatment, Dae-hyun accompanying her. Enjoying 'time off'South Korean media later made an update on the attack, reporting that authorities had stated that she had emerged without a scratch. In reality, she came out of the ordeal with a broken leg and arm, along with other more minor injuries. That didn't stop her from using her time off by assisting Dae-hyun with assembling her new mech. She thanked him for being there for her when she'd needed him.

D.Va is used as the symbol for the National D.Va Association, a progressive feminist movement composed of Overwatch fans. The group achieved international notability after a photograph of their flag—featuring D.Va's bunny-ears logo—was photographed in a news report for an international Women's March event in Seoul on January 21st, 2017. Based in South Korea, the group chose D.Va as its symbol owing to an earlier incident where professional teenage Overwatch player Geguri was accused of cheating owing to an eighty percent win rate; which some believed was 'impossible' for girls to achieve.
The group distributes stickers of D.Va's bunny logo, among other paraphernalia. It plans on finding new ways to use Overwatch as a tool for spreading its message. Charlett Chung, who is D.Va's English voice actor, has commented positively on her character, commenting 'in terms of representation of Asian-American characters in video games, particularly women, they might be over-sexualized - and I don't know if I'm being too candid here - I feel like D.Va is more of a real person. She happens to have some sex appeal, but that's not why she's in the game. She's not there to be an exotic lotus.'
