New to 3D Printing? Here are 7 Tips

Published

on

Not too long ago, 3D printing only existed in science fiction. Today, it is fast becoming part of everyday life, far from the closed world of laboratories and factories.

Today, anyone who is interested in 3D printing can access the hardware at a reasonable price. But even though the technology is more accessible than ever, it is still a relatively complex matter.

Here are our 7 tips for 3D printing:

Master Calibration

One of the first things you must learn how to do is to calibrate your 3D printer for the most accurate results. This should be one of the very first skills to learn.

If you haven’t calibrated your printer properly, you can easily end up with everything coming out wrong, including your tester cubes.

Invest in digital calipers that will help you to measure precisely the dimensions of your test object.

Start by printing basic objects like cubes and other objects with interesting angles. Your calipers will help you to check the accuracy of the process.

Square Off

It will take a while to master the skills to create excellent objects. Get familiar with the 3D printing process and hone your skills with practice.

Get practice by printing out many square cubes measuring 20mm. As you do this, you will also be getting familiar with your device and how it works.

You don’t have to do boring cubes. Cut cross-sections, add hollow items, and these will help you to check the accuracy of the perimeters.

Patience Pays

If you are in a hurry, you may find that the reality is far from the expectation. The truth is that it takes some patience and skill to come up with functional print outs.

Give yourself time and embrace the learning process. If you give yourself time, you will become successful at it.

The Whole is Greater than the Sum of the Parts

Once you have made enough cubes, you can move on to more complex objects. One of the best ways to work your way up is to start with complex objects that you assemble manually.

It is easier to print many simpler objects than to print our complex objects. Errors are a lot easier and cheaper to correct without redoing everything.

Learn CAD

Computer-aided-design or CAD is a technique for creating the 3d printed designs that you feed into your 3D printer and the designs determine your output.

There are a lot of 3D printers who never learn CAD. But they can only use designs from other people. They cannot come up with their own designs for 3D printing.

Once you learn CAD, you can pursue your 3D printing passion even further.

Starting from a design to a physical end product will give you so much satisfaction.

The 0.25mm Margin Rule

What happens when you print out your designs but they don’t fit together? The 0.25mm rule comes in handy to provide you a margin of error so that all your moving parts fit.

If you plan on inserting a pole into a larger block, the hold should be larger by 0.25mm. This extra 0.25mm is your margin of error.

Plug In

There are tons of people who have already started 3D printing. If you plug into their online communities, you can exchange information and learn from other people’s experiences instead of making all your own mistakes.

These communities are rich sources of information, inspiration, and designs. 3D printing is a fairly complex venture and you will need all the help you can get.

3D printing is a fun and exciting hobby. Follow these tips and you will grow into a 3D printing expert.

In a market flooded with budget smartphones, it’s easy to overlook new entrants. However, Coolpad, a relatively new brand in the Philippines, is making waves with its COOL 20+ model. Priced at just PHP 5,699, this phone aims to offer a decent package without breaking the bank. But how does it stack up against its competitors? Let’s dive in.

Design and Construction

  • Aesthetics: The COOL 20+ sports a minimalist design, with a glass back panel that adds a touch of luxury rarely found in this price segment. The metallic flake in the paint makes the phone sparkle under bright lights, giving it a premium feel1.
  • Build: The frame is made of durable plastic, and the phone comes with a rubber case for added protection.
  • Port Placement: The phone features a USB-C port, loudspeakers, a dual-sim card slot that doubles as a microSD slot, and a 3.5mm audio jack.
  • Ergonomics: Weighing 197.1 grams, the phone is on the heavier side and feels a bit bulky.

Display and Multimedia

  • Screen: The phone features a 6.52-inch IPS LCD with relatively thick borders. The colors are decent, and the screen is bright enough for outdoor use.
  • Audio: The downward-firing mono speakers are loud but not the best in terms of quality.

Performance and Benchmarks

  • Chipset: The phone is powered by a MediaTek Helio G85, an older chipset first introduced in 2020.
  • Memory: It comes with 6GB of RAM and 128GB of storage, expandable via a microSD card.
  • Gaming: The phone can handle light gaming but struggles with more graphics-intensive titles.

OS, Apps, and UI

  • Operating System: The phone runs on CoolOS 2, based on Android 11, and doesn’t seem to offer an upgrade to Android 12 or 13.
  • User Interface: The UI is simple and easy to use but lacks flair.

Cameras

  • Rear Camera: The dual rear camera setup features a 48MP main lens and a 0.3MP sensor. It performs well in well-lit conditions and even in low-light scenarios.
  • Front Camera: The 5MP front camera is average but gets the job done in good lighting conditions.

Battery and Connectivity

  • Battery Life: The 4500mAh battery lasted 14 hours in the PCMark battery test.
  • Connectivity: Basic features like Wi-Fi 5, Bluetooth 5.0, and GPS are available.

Conclusion

The Coolpad COOL 20+ offers a decent package for its price. While it does have its shortcomings, such as an older chipset and limited OS upgrades, it makes up for it with a good camera and a premium glass back panel. If you’re willing to overlook these limitations, the COOL 20+ could be a budget smartphone worth considering.

So, is the Coolpad COOL 20+ the budget smartphone for you? With a plethora of options available, the choice ultimately boils down to what you prioritize in a phone. But if you’re willing to try something new, the COOL 20+ might just be the phone to break the monotony.
