One of the most remarkable technologies to have been developed in recent years has to be that of 3D printing. This technology enables you to use a specialized printer to create the things you design on a computer with the help of certain materials. If you are planning to use this technology, it helps to know a bit about it like the working of the technology, salient features, scanners and 3D modelling applications, how to print etc.
How Does This Technology Work?
In order to 3D print something, you need to create the concept art of the object first. A virtual design has to be created in the form of a specialized file such as CAD. CAD files can be created with the help of a 3D scanner if you are planning on cloning a specific object. A 3D modeling application will also suffice if you want to create the design on your computer.
3D Scanners: These specialized scanners can make use of various technologies in order to create a 3D model. Some examples include volumetric sacking and structured light among others. 3D scanners are an important part of 3D printing technology but they can be rather expensive but cheap DIY kits are also available.
3D Modeling Applications: Like scanners, you can find a range of these applications. Professional grade applications are quite costly. On the other hand, free or cheap applications are also available for beginners to create concept art with. Some applications even come with tutorials to help you get started.
Printing the Model
Once you have readied the model, you need to work on it further to get it ready for 3D printing. In order to prepare the model, a process known as slicing is used. In it, the model is sliced into numerous horizontal layers. In order to do so, you need a specialized software. Some modeling applications have this function built into them. In some cases, you may have to use a specific slicing tool that is compatible with the 3D printer. Once completed, the actual printing process can be started. The time required for the printing to be completed depends on the printer you are using, the materials you are working with and the complexity of the structure.
3D printing technology has certainly progressed far. However, it still has a long way to go till it becomes a part of homes like regular 2D printers.

Tips on Making Distributed Agile Successful
Purists and Scrum hipsters will argue that dispersed teams are a taboo in Agile communities of practice. However, in reality there are many instances where an organization has to outsource due to lack of local skill set or other reasons. Being prepared for what to expect and how to approach and prepare for the facilitation of distributed teams can go a long way in ensuring the success of the Agile initiative.
1. Decide on how to distribute
- Teams work differently in their remote locations, but the whole team officially syncs up at least once a day, but also ad-hoc as situations call for it;
- ach team in each location has all the necessary skills to execute on the committed sprint backlog;
- Individuals in different cities must be encouraged to work as one team as opposed to one team in country A and another in country B;
2. Create stickiness or coherence
- We want teams that will stick together which requires a clear vision;
- We therefore acknowledge that cultures in our team differ – we should encourage collaboration and relationship nurturing early on in the project for sub-cultures to form;
- Work actively to strengthen tactical as well as team structures;
- Build trust through early communication of progress
3. You’re going to have to change how you communicate
- In the Cinderella Project (a perfect project) a team would come together from their disparate locations to meet, socialize and form cohesion;
- We encourage teams to stay together for at least an iteration;
- Learn the lay of the land
- Become familiar with the ‘flavour of Agile’ being used (e.g. all teams estimate, collaborate, execute and communicate differently – get to know these traits – it’s going to make or break your Agile initiative!)
- Organize quarterly visits for either the whole team or have people cross pollinate through travelling between locations
- Invest in the concept of having team ambassadors, people that ensure good working relationships
- A Wiki culture, or information sharing philosophy is going to be very important, more so than with co-located teams
- You are going to need more meat on that product backlog to physical counter the absence of key people
- Horizontal communication must be encouraged and drive
- Distance isn’t such a problem, time zones are!
“When transitioning to a distributed team, err on the side of over-communicating.“
4. Additions you’d need to accommodate in the framework you are using:
- Meetings will require slack time, people are going to catch up (and rightfully so) whether you like it or not;
- Share news as it happens about the project, good and bad
- Honour basic meeting etiquette:
- One conversation at a time
- Everyone must know who is speaking
- Keep to the time-boxes
- Facilitator to set up technology, conference bridge etc. in advance of meeting, and test the connections
- Ensures everyone has the right dial-in information
- You’ll have to ensure your technology supports your dispersed nature
- Use Agile Lifecycle Management tools like Jira, VersionOne etc
- Use proper high quality video and voice tools to video-conference successfully and to bridge the distance gap
- Online whiteboards for design sessions will aid collaboration
- An online Retrospective tool that will ensure the opportunity to improve isn’t lost

Drones make very popular gifts for children and with so many models available for kids, you will find one that your child will love flying. Drones are generally safe for children and you therefore have nothing to worry about. You can actually improve your family time when you get a drone for your kids complete with a camera to capture those moments in the park or around the house or garden.
The good thing about kids is that they are fast learners and it will take a short moment for them to learn how to safely control the drones. It is however still important that you supervise the kids as they enjoy the flying. When you are out looking for the best drones for kids, you will realize that quality increases with price. But there are so many sturdy and cheap drones you can get for your kids. With the right selection, you will be able to purchase a drone that is easy to fly, easy to maintain and one that is durable for that matter.
Consider the minimum flying age
The truth is that drones are not suitable for kids of any given age. Drone manufacturers do give age recommendations when it comes to the mini drones with eight years being the cut for most. You can however also use child maturity to determine what age is perfect for them to own and fly a drone. Whereas age of 10 may look suitable enough, children who are familiar with robotics and such may be able to fly the drones at younger ages. The age should also guide to the drone features that are relevant. For instance, kids over age of 12 will most likely find action camera drones more appealing than those without.
Check speed and size
These are the two elements that play a role in drone accidents. When choosing drones for kids, it is safer that you go for the model made of ABS plastic that is lightweight and durable. This kind of a drone eliminates the damage that could be caused by a much heavier or larger drone, especially when a child is just learning to fly. Small toy drones are basically harmless. Lower yaw rate are also best for kids. Propeller rotating speeds should be selected accordingly to minimize dangers when children are learning to fly. Slow flying drones are safer for kids, but you can always upgrade the size and speed according to the age and skill achieved.
Think about flying environment
You can either get an indoor or an outdoor drone for your child or one that can be flown in both environments. Indoor drones have stable hovers and very responsive commands whereas outdoor drones should at least be wind resistant and feature motor power to keep hover stable. Before buying, ensure that you have enough space to fly it, whether indoors or outdoors. The last thing you want is to have your kids fly the drones in your neighbor’s space which can be privacy invasion.
Drones for kids can keep them busy and excited as long as you choose a safe and secure model. Find out all about the drone before buying so you are sure it is the best for the child.

Each release comes with the aim to bring improvements in the flying experience. This new technology actually has great potential for different industries and choosing the best drone is what you should be paying attention to in relation to your needs. Whether you are getting a drone for your new flying hobby or for business, there are things that you must take into consideration to end up with the best model. Below are helpful questions you should answer to guide your purchase.
What is my intended use? Remember that different drones have different features to complete specialized tasks easily. If it is just for flying fun, for instance, then it should not matter whether it has a camera or not. If it is for taking pictures and videos, however, then you want to make sure that it comes with a premium camera that you can trust for quality images. Let the tasks that you wish to complete with your drone lead you to the best drones for sale.
What is my budget? Apart from what you can afford, the intended use can determine what amount is reasonable for a drone. Recreational purpose drones are cheaper compared to those that are created for specialized tasks. The rule here would be to get a drone that you can afford and one that gives you the flying experience that you are looking for. For instance, cheaper drones may prove harder to fly for beginners because they lack some features that would otherwise make flying easy. Repairs and maintenance should also feature in the budget considering that drones are crash prone.
What type of drone is more convenient for me? Getting familiar with the types of drones available in the market is paramount in making the most suitable decision in terms of purchase. The types are differentiated by the features and the common drones today are ready to fly or RTF, BNF or bind and fly drones, ARF or almost ready to fly drone, RTH or return to home drones and FPV or first person view drones. You will also find drones with GPS navigation. These types offer varying assembling and flying experiences and you should consider each one before deciding what type works best for you.
Are there are any registration requirements? Usually the weight of the drone will determine whether you need to register it with the relevant agency of not. Most toy drones are not heavy enough to require a registration but you might need to register more sophisticated business related drones to avoid civil penalties. Apart from registering, you will need to adhere to flying guidelines. For instance, you may not be allowed to fly above given heights and near airports.
Where will I fly the drone? This is very important because there are places that are off limits. Think safety and legality when looking at drones for sale.
There are a huge variety of drones for sale. To make the right choice you would have to be clear about your needs so you select a drone with all necessary features to make your flying experience most rewarding.
