How to 3D Print

Three-dimensional object is solid. Additive 3D printing process where materials are exposed in successive layers using different sizes are obtained.
Material 3D Printer is usually done printing process using digital technology. Treatment (with high accuracy the exact amount) is usually removed from the feed milling and grinding.
Personal manufacturing machines "fabbers" or "3D fabbers", as it is known. [Version needed]
The term "3D printing" was established in 1995 when MIT PhD Tim Anderson Jim Bredt and revised inkjet printer powder bed and not binding resolution ink on paper extrude. Z Corporation 3D printing companies advanced after the patent (Bredt and is formed by Anderson and is now owned by 3D Systems) and manage the creation of ExOne.
Modeling
Computer Aided Additive Manufacturing (CAD) or animation modeling software to design and print a victory toast for them to be used as a guide for digital cross-sections of the virtual machine takes plans. Machine used depending on content or binding materials together to build a platform bed or layering material / binder is complete and final 3D model is "printed". format film scanner input file and VRML (or WRL) files to 3D printing technology can print in full color is often used as input.

Printing : How Pow

To perform print books machine design and continuous layers of liquid, powder, or a series of cross-sections of the model allows for the construction of sheet metal. Layer with a thickness of 100 microns (0.1 mm) is about Objet Connex 3D Systems PROJET series and series 16 microns thin, some machines can print layers as . XY resolution compared with laser printers particles (3D dots) with a diameter of 50 to 100 micrometers (0.05 to 0.1 mm).
Construction of a model with contemporary methods from several hours to several days, the methods and models can be based on size and complexity.
Injection Molding polymer products such as traditional techniques to produce large quantities are more expensive, but added production faster, more flexible and more expensive when parts are relatively small amounts can cause. 3D printers teams of designers and concept development and conceptual models using a desktop size printer offers the ability to create.

Problems by observation

Printing in material A worked fine, now material B doesn't print well!

See the section on Polymers and "Troubleshooting: Solving flow related problems".

Brown sludge forms on the extruder head

If your printer came with an ABS Fix Kit (a piece of ABS filament), running this through the extruder will seal up any small leaks around the printer head. If for some reason you did not get this kit, any piece of 3mm ABS filament will do.

Plastic comes out of extruder head in a flowing state

If you turn the big extruder wheel manually, the plastic exiting the extruder head should form a thin line of plastic that hangs from the extruder head. In general, start at 215C for PLA plastic and 225 for ABS plastic.

The extruder stops extruding

There are several possible causes for this:

You are trying to extrude when the extruder is still cold. This may take quite some printing to get the last remains of ABS out of the extruder. Heating it to a higher temperature in general allows you to print at the higher speeds.

Possibly, liquid PLA is pushed upward in the extruder to a section where no heating is applied. Normally, the (low friction) bowden tube has such a low friction that you can still push out the solidified PLA with some force.

When the extruder has jammed, the material-feed mechanism may continue to push material into the extruder. Even if you're using PLA, one color of thermoplastic may stick perfectly while another color does not stick at all: this is because the colorants affect the melting point, also shift the recommended print temperatures.

If you have trouble getting the first layer to stick, you can do several things:

Make sure the print head is almost touching the platform for the first layer. If this works better, you can make this permanent by changing the height of the Z-limit switch at the back of the machine (the top one).

Just when the print starts, you can turn the extruder-drive's gear a little to get increase the material flow for the first layer. Don't worry, you will not damage the motor by pushing it through its steps, it will just skip a few steps which is totally harmless!

If you're printing directly onto the acrylic platform, sanding and/or scratching the acrylic will help to create a stronger bond.

Try raising your extrusion temp a few degrees, even bumping the print temp by 5 degrees or so can really make a difference.

Ensure that the bed is level. If it isn't level, this will create a good bond in one place, but the head will be too high in the other.

 For the first layer, during printing you can increase the 'flow rate' through the Real Time Tuning feature (by clicking the icon with the sliders). Cleaning it with some rubbing alcohol removes the grease and makes the PLA stick easier.

My 3D prints do not look good!

Analyzing your first print (a great post by Florian on his blog)

Check if the fan (near the print head) turns on after the first layer has printed. If you print an object with a thin cross section very fast, it will not have time to cool. This can have several causes, each cause requires a different approach to solve it.

The causes and solutions are discussed in: Troubleshooting: Solving flow related problems.

Mechanical problems

X/Y axis

The extruder head stops moving during a print, or doesnt move at all (even in manual mode). Pushing directly on the print head assembly twists the bushings and causes them to jam. This would lead to slightly trapezoid prints which are no good for prints that need to be mechanically accurate. Click on the picture to see more details and annotations on the image.

When a layer is printed, the perimiters and infill of the object do not or barely touch. However, there are several cases that can cause irregular behavior:

If the printhead is not levelled out correctly, the print will deposit more on one side then the other, causing it to ripple or even warp prematurely.

If the printhead is level but the print looks shakey, it can be caused by several problems:

The Z-axis rod may have bent during shipping.

The Z-axis rod is not correctly seated in the aluminium holder.

The print is warping while printing, or has come loose on several parts.

The most important settings are:

Dimension

This feature should always be activated, otherwise you get no extrusion on your Ultimaker.

Retracting can be enabled, if you have more patience and want a higher quality build. With ReplicatorG, we added a feature which which you can increase/decrease the printing speed and flow rate together, during printing. This is a nice way to discover the printing speed that works well for a certain type of object.

The travel feed rate can be 250 or even 300 if your printer runs smoothly enough to handle it.

The perimeter feed rate and perimeter flow rate settings can be lowered to make the outline of the object print at a slower speed, which usually improves print quality. Use the same number (say 0.75 or so to start) on both settings.

Comb

Comb is a nice feature that makes sure the print head does not travel through holes.

Chess History

The starting of the ancient history of chess has been linked to the Indians, both by the Arabs and by the Persians. However, the starting of the chess game appears to remain lost. The ancient scripts for chess in both Arabic and Old Persian are " shatranj " and " chatrang " respectively words derived from the Sanskrit word " chaturanga ", which literally translated means, an army of four parts.

Chess in ancient timings was spread throughout the world and many same games soon began taking shape. A version of the ancient chess game was taken from India and also introduced to the Near East.

Silk Road people, Buddhist, and many others carried away ancient chess boards to the Far East where it was reshaped and transformed into a game that was often played on the chess board intersections, rather than within the squares. Chaturanga came to Europe through Persia, and the Arabian. Muslims spread chess to North Africa, and Spain by the tenth century.

The historic ancient chess game was developed in Europe, and by the late fifteenth century, it had survived various Christian Church sanctions and prohibitions, and almost took the same shape as the modern game we know today. Modern times saw that new reliable references work, exciting new variants, and competitive chess tournaments add to the already famous popularity of the game. Reliable time mechanisms, effective rules, and charismatic players also further bolstered the popularity of chess.

In the next phase of the history of chess is known as the earliest ancient precursor of modern chess, and it flourished in India by the sixth century. It is the earliest known game to have 2 critical features found in all modern chess variations. Firstly, it has different pieces with different powers (which is not a feature in GO and Checkers), and victory depends on the fate or capture of one piece, now called the king in modern chess. Other game pieces that are uncovered in archaeological findings are considered to have come from other, distantly related chess-like board games. Some of these types of ‘chess board games’ had as many as hundred squares or more.

In the late 19th century, Captain Hiram Cox and Duncan Forbes discovered that the original form of was played with four hands. Other scholars who studied ancient chess history have concluded that a 2 handed version probably existed before the 4 handed one and that it probably then evolved into many other versions, including the 4 handed version.

One literal translation of the Sanskrit word "Shatranj" can mean "Having 4 limbs or parts" and this often means an army in epic poetry. The ancient name itself comes from a battle formation named in the Indian Mahabharata epic. Ancient Shatranj was a game that simulated battle and which was truthfully based on Indian military strategy of the time. The initial dice and gambling aspects of the game were later removed as the game progressed and branched into newer variations

How Chess Pieces Move

Before you can play a game of chess, you need to know how to move the pieces (legally). A chess piece’s power is tied to its mobility. The more mobile a piece is, the more powerful it is:

Pawns: Pawns can only move forward. On their first move, they can move one or two squares. Afterwards, they can move only one square at a time. They can capture an enemy piece by moving one square forward diagonally.
Bishops: Bishops can move any number of squares diagonally.
Knights: Knights can move only in an L-shape, one square up and two over, or two squares over and one down, or any such combination of one-two or two-one movements in any direction.
Rooks: Rooks can move any number of squares, up and down and side to side.
Queens: Queens can move any number of squares along ranks, files and diagonals.
Kings: Kings can move one square at a time in any direction.

Goal Of Chess

Remember your goal is not to kill all the pieces of opponent neither you can do it but instead you have
to check mate your opponent king

Check Mate

Check Mate is the stage when either of the two players there is one who cannot move its King to any possible box and there is no other piece that can save the king.

Getting Better at Chess

Knowing the rules and basic strategies is only the beginning - there is so much to learn in chess that you can never learn it all in a lifetime! To improve you need to do three things:

Play

Just keep playing! Play as much as possible. You should learn from each game – those you win and those you lose.

Study

If you really want to improve quickly then pick up a [recommended chess book]. There are also many resources on Chess.com to help you study and improve.

Have fun

Don’t get discouraged if you don’t win all of your games right away. Everyone loses – even world champions. As long as you continue to have fun and learn from the games you lose then you can enjoy chess forever!

How To Build Weight And Be Healthy

For many thin guys around the world, gaining weight without using illegal steroids has been a challenge. For thousands of lean young men, the dream is to gain weight, but no matter how much they eat they remain thin. Some people are naturally thin; that means their genetic makeup is in such a way that the body burns more calories than others. The very basic method of weight gain is to eat more calories than your body burns off. By providing the body with more calories, this balance can be altered and body mass can be increased. Weight training is of great importance in this context, which enables the body to absorb more nutrients from the food by increasing the level of certain hormones and increasing the muscle mass.
There are many incorrect beliefs and theories bout building muscle. The type of food to be eaten is an important factor which decides the type of weight gained, whether it is muscle mass or mere accumulation of fat. Some types of calories are not equal to others for gaining muscle; because most processed junk food contains empty, totally nutritionless calories. These foods promote accelerated fat storage, and do not provide the body with the correct nutrients essential for gaining muscle. High quality protein, which the body breaks down into amino acids, should be the centerpiece of all your meals. Intense exercise increases demand for amino acids, which support muscle repair and growth.
Another factor is the selection of the right type of weight training. Resistance exercises will help with muscle growth. Whereas aerobic exercises can result in the reduction of weight. For maximum muscle gain, the focus of your workouts should consist of free weight exercises, rather than machines or bodyweight exercises. To get a very effective workout, you must stimulate as many muscle fibers as possible, and machines do not do this. The main reason for this is a lack of stabilizer and synergist muscle development. Stabilizer and synergist muscles are supporting muscles that assist the main muscle in performing a complex lift.
The results of weight training can vary from person to person, and will usually depend on your consistency and commitment to your program. You should have the patience and motivation for building a powerful body with a consistent diet and exercise schedule.
Exercise Guidelines for building muscle:
Weight training involves the use of equipment that enables variable resistance. This resistance can come in the form of free weights like barbells and dumbbells, machines that use cables or pulleys to help you lift the weight, and bodyweight exercises like pull-ups or dips. The more stabilizers and synergists you work, the more muscle fibers stimulated. The exercises that work the large muscle groups are called compound (or multi-joint) movements that involve the simultaneous stimulation of many muscle groups. These compound exercises should be the foundation of any weight training program because they stimulate the most amount of muscle in the least amount of time. Multi-jointed free weight exercises like the bench press require many stabilizer and synergistic muscle assistance to complete the lift.
Free weight exercises like the dumbbell press or squat put a very large amount of stress on supporting muscle groups. You will get fatigued faster and not be able to lift as much weight as you did on the machine. But you will gain more muscle, become stronger very quickly and have a true gauge of your strength.
If you use machines in your program, they should be used to work isolated areas and only after all multi-jointed exercises have been completed. Beginners should begin with a limited combination of machine exercises, bodyweight exercises and multi-jointed free weight exercises. Before increasing the weight levels, they should work on becoming familiar with the proper form and execution of each.
The following are some proven basic exercises to encourage muscle and strength gain unlike any other exercises.

Bench Presses - works the chest, shoulders, triceps
Overhead Presses - shoulders, triceps
Pull-ups/Barbell Rows - back, bicep
Squats - legs, lower back
Dead lifts - legs, back, shoulders
Bar Dips -shoulders, chest, arms

What WIl Happen? How Pow

To build mass, you must weight train with heavy weights. To consider a weight heavy, you should only be able to do a maximum of 4-8 reps before your muscles temporarily fail. A weight is considered 'light' if you can do more than 15 reps before muscle fatigue sets in. Heavy weights stimulate more muscle fibers than lighter weights which result in more muscle growth. Heavy weight training puts a huge strain on your body, so adequate rest and recuperation after your workouts is essential.
Eating guidelines for building muscle:
A high protein diet is an inevitable part of any weight training programme, importantly, protein derived from animal sources. Proteins you need to be concerned with are those found in whey, casein (cottage cheese), eggs, beef, poultry, and fish. Soy protein, tofu and bean curd are some alternatives. Eating the right amount of foods consistently will force your body to grow beyond what you may think possible. The diet also should contain an adequate amount of carbohydrates (potatoes, sweet potatoes, yams, oatmeal, cream of wheat, cream of rice, rice, beans, bread, pasta, all cereals) and fat. Green leafy vegetables and fruits also should be included.
When you train with weights, you should eat a minimum of 1 gram of protein per pound of body weight. You also must have protein at every meal. To enable your body to actually assimilate and use the all the calories you will ingest, you have to reduce your meal size and increase your meal frequency. Splitting your calories into smaller, more frequent portions will enable food absorption and utilization of nutrients.
During the past 20 years there have been great developments in the scientific understanding of the role of nutrition in health and physical performance. Studies shown that adequate dietary carbohydrate should be ingested (55-60% of total energy intake) so that training intensity can be maintained. Excess dietary saturated fat can exacerbate coronary artery disease; however, low-fat diets result in a reduction in circulating testosterone. So the balance between protein, carbohydrate and fat should be maintained.
So the focus on weight gain programmes must be on two components, lifting heavy weights, which will stimulate the largest amount of muscle fibers. Your body responds to this stimulus by increasing your muscle mass and secondly eat more calories than your body is used to. When you overload your system with plenty of protein and fats, your body has no other choice but to gain weight.
A Mass Gaining program is incomplete without the timely measurements to monitor your progress. Without it, you won't know how exactly your body is responding to your diet and training routine. Just looking in the mirror and guessing is not acceptable. If you want to start getting great results, you must develop the habit of accurately tracking your progress. This also provides the motivation to continue with the weight gain schedule and for the further progression. So even though you have a very thin body type, and haven't been able to gain weight no matter what you try, you will definitely succeed with a well planned weight gain programme.

What Is Dowsing

Dowsing is a process of starting your own and surrounding etheric energies to work with your subconscious mind by applying the so called idiomotor effect that can unconsciously move your body parts and give indications that can be further amplified by a specific tool.The person who does this activity is called a Dowser.

It is Fun ! .HowPow.

From past 1000 years dowsing has been done by many people for there daily or special needs.Dowsing allows you to get a yes no answer to any question in just seconds.If you want to ask a special question you need to work on it but guess what when you have done work on it you will get What You Want!. Just Try it for fun and enjoy the benefits for i personally use to dowse for last 5 years.

What was My Experiance.... .HowPow.

If you ask me that what was my experiance ! then well i would say that it is the best thing that i have learned till now.The best thing i saw about it is that whenever i want to have a quick answer to a problem i just consult with pendulum.Then i note my readings. This helps me to record my previous readings and also help me to maintain a future analysis tool.

What is Pendulum Dowsing.? .HowPow.

Pendulum is a tool used in dowsing to get simple YES and NO answers. It is the best dowsing tool ever but still it depends on the intent of dowser that what is required.Some dowsing tools are very big in size and cannot be carried every where you have have to become just like a doctor carrying a first aid box every where. But that's not the case with pendulums. Pendulums are very small and can be carried with ease.One example is that i always carry it with me in my pocket.

How to setup a pendulum for dowsing ? .HowPow.

Print the above given chart

Now at first you hold your pendulum string in your one hand. At this moment your pendulum will be at downward direction then you start to ask this simple question.

Q : What is my right answer ?

Pendulum Reaction :
: Your Pendulum will start to move.
there are three 3 possibillities of your pendulum . Note : it depends on person to person.
: This movement of pendulum is your movement for every right answer means that when ever you will ask anything from your pendulum and if the answer is also right you will get the same directional movement

SIMILARLY ASK

Q : What is my wrong answer ?

Pendulum Reaction :

there are three 3 possibillities of your pendulum . Note : it depends on person to person.
: This movement of pendulum is your movement for every wrong answer means that when ever you will ask anything from your pendulum and if the answer is also wrong you will get the same directional movement

There will be another move that will determine a maybe answer.

Three Possible Motions:
Here are basic three most common motions of a dowsing pendulum.

ClockWise Circular motion (Can be of right ,wrong or maybe) mostly "RIGHT"
AntiClockWise Circular motion (Can be of right ,wrong or maybe) mostly "WRONG"
Linear (In straight line) (Also Can be of right ,wrong or maybe) mostly "MAYBE"
