This detailed blog will look into the complexities of 3D printing costs. We will also examine various pricing factors, compare them with traditional manufacturing methods, and envision future trends that may shape its economic landscape.

What is 3D Printing?

Let's first examine the principles of 3D printing before getting into the price specifics. 3D printing, also referred to as additive manufacturing, is a technique that builds three-dimensional objects from digital models by depositing layers of material one after the other. With this technology, complicated geometries that would be difficult or impossible to fabricate using conventional manufacturing techniques can now be created. For various uses, including rapid prototyping, bespoke part manufacturing, and artistic pursuits, 3D printing provides an adaptable answer.

What are the Factors Affecting 3D Printing Costs?

Several factors influence the cost of 3D printing, each significantly determining the final price tag. Here are some crucial things to remember:

1. 3D Printer Cost

The initial cost of purchasing 3D printing equipment can significantly influence the total cost of printing. Knowing the pricing model for 3D printing services is essential. For instance, we include a fee per gram of material used along with a base fee for each print job. Our service charges $0.30 per gram of material used plus a $3 base fee for each print job. Typically, material expenses amount to around $20 to $30 per kilogram for individuals who own their printers.

2. Materials

Another critical factor that affects cost is the selection of printing materials. Different materials have varying price points and performance qualities, including plastics, metals, ceramics, and composites. Although they may be more expensive, specialty or high-performance materials provide improved attributes like strength, durability, or heat resistance.

3. Number of Perimeter Walls

Perimeter walls, also known as shells or outlines, are the outer layers of the printed object. They provide the shape and surface finish of the object. The number of perimeter walls determines the thickness of these outer layers. Increasing the number of perimeter walls enhances the print's surface quality, strength, and stability. However, it also increases the price, print time, and material usage.

4. Infill Percentage

When you design a 3D model for printing, it's not always necessary to print the entire volume of the object solid. Infill percentage determines how much of the internal space is filled with material. A higher infill percentage means more material inside the object, leading to increased strength, higher material usage, and longer print times. Conversely, lower infill percentages result in lighter, faster prints but with reduced structural integrity.

Advantages of 3D Printing

Comparing 3D Printing Costs with Traditional Manufacturing

While there are many benefits to 3D printing regarding speed, flexibility, and customization, a complete picture of its economic impact requires comparing its cost-effectiveness with more conventional manufacturing techniques. Here's a comparative analysis:

Cost Advantages of 3D Printing

Lower Tooling Costs: 3D printing eliminates the requirement for expensive molds, dies, or tooling setups necessary for traditional manufacturing procedures. This financial gain benefits custom projects or small-scale production runs when standard tooling costs would be prohibitive.

Unmatched Design Freedom and Customization: 3D printing frees designers from the limitations of conventional manufacturing techniques to create complex shapes, elaborate patterns, and unique geometries. Because of this flexibility, designers can quickly iterate, tweak designs for performance, and customize products to meet specific needs without paying more for setup or additional gear.

On-Demand Production: Large minimum order quantities (MOQs) are sometimes required in traditional manufacturing to cover setup costs. This results in excess inventory and storage costs. On the other hand, firms can produce what is needed when it is required, thanks to 3D printing, which reduces waste, inventory costs, and obsolescence risk.

1. Line Drawings and Mockups

Line drawings and mockups are the earliest forms of prototyping, often created during the initial stages of product development. As the name implies, line drawings are straightforward pictures that show a product's fundamental composition and features. Using materials like cardboard or foam, mockups, on the other hand, are tangible representations of the product. Visualizing and communicating design concepts is the primary goal of this kind of prototyping.

Line drawings and mockups are advantageous because they facilitate quick brainstorming, are affordable, and allow for gathering early input. Without requiring a substantial investment of time or money, these prototypes assist clients and stakeholders in understanding the general appearance and feel of the product.

Examples Suited for this Prototyping: Mockups and line drawings work best for the early conception stages of projects. These may involve developing a new device design, developing the packaging, or making preliminary user interface designs.  Line drawings are also used for patent application submissions.

2. Digital Prototypes & Renders

Digital prototypes and renders move the prototyping process online and creates models that can then be produced. Designers construct detailed three-dimensional (3D) models of the product using computer-aided design (CAD) software. These digital representations allow for a more in-depth exploration of the design, including its functionality and aesthetics.

Digital prototypes have the advantage of being able to quickly iterate designs, replicate real-world situations, and share the virtual model with colleagues with ease. This kind of prototype speeds up the process of fine-tuning the design and drastically decreases the requirement for natural resources.

Suitable Projects for this Prototyping: Digital prototypes are ideal for tasks requiring a great deal of accuracy and detail. Digital prototyping is very beneficial to the automotive, electronics, and consumer products industries. For example, designing a new smartphone, creating intricate mechanical components, or refining the ergonomics of a product can be efficiently accomplished through digital prototyping.

Lawn Da Vinci

Thanks to all that came out to see us us at Kansas city Makerfaire.  I will be updating and adding to this post so stay tuned.

Cad Model of Robot Lawnmowers

So, you want to make your own remote controlled lawn mower like in the movie "Honey, I shrunk the kids" ? You should. This is a fun project that is very practical and makes mowing the lawn a lot more enjoyable. You will learn a few new skills along the way that will help you be a better maker.

First, a disclaimer. Robots are dangerous. Lawn mowers are dangerous. Robot lawn mowers are the danger of mowers times the danger of robots. KC Proto is not responsible for any damage to anything living or inanimate. This project was possible because of the spirit of open source. Pay anything you learn forward. Suggestions on improvements are welcome.

I. Gathering materials

There are a lot of parts to this project and a few ways to customize it to suite your purposes. These are the supplies I used and they work well.

1. Lots of angle iron and steel- I used 2 inch angle iron and, in retrospect, it was a little bit of an overkill. It is strong enough for me to ride though.

2. Mobility scooter motors- There are a lot of used motors on ebay and they are all pretty similar. If you can get them with the tires on, it will save you a lot of time.

3. Lawn mower - Find a cheap push mower. Any mower should work but make sure it is reliable and it starts.

4. RC remote- I used a Tower Hobbies System 3000 and it works well.

5. Other electronics- There are a few ways to do this but I used an arduino pro mini, a raspberry pi, a Sabertooth 2x25 motor controller, a relay and a webcam. More on this later.

6. 2 Batteries- Pretty much any 12v car or marine battery should work. 2 trickle chargers fill up the batteries in between mowings.

7. Beer hat- Optional, but highly recommended.

Gathering Material

II. Planning

You don't have to make a full CAD model but a little planning goes a long way.  I modeled a rough plan of what I was looking to make in Onshape and is available to view here for reference.  You will want to make sure your batteries, motors and lawn mower all fit together well and that you won't have any clearance issues.  

Cad Model of Robot Lawnmowers

III.  Making the frame

If this is your first time making something like this (like me) you are going to need some help and the right tools.  If you are in the Kansas city area, I recommend going to a place like Hammerspace Workshop.  The right welding equipment, saws, grinders and help are going to make this a lot easier.  Measure twice cut once.

Making the Frame

IV. Painting the frame

Time to put some lipstick on that pig of a frame you have made.  Doing this step right will make your mower rust resistant, cover up a little bit of your weld job and ensure it lasts long enough pass down to your children.  Your frame is going to be very greasy and dirty at this point so clean it very well with a degreaser.  Putting your frame up on blocks will help you get into some of the harder to reach places.  If you are painting in your garage, think about what size your tarp needs to be and get the size larger than that.  Let's just say I didn't follow this advice.   Since you are painting on raw steel, primer will help make sure you have a nice even coat.  I used Krylon Rust Tough enamel primer and paint from my local auto parts store with good results.

Remote Controlled Lawn Mower

V. Attaching the mower and wheels

The best way I found to approach this was to use existing wheel hardware to attach to to the frame.  I had my planned mower blow up mid project so I had to improvise with a different mower.  Before you take off the wheels, take note of the deck height and replicate that in your design.  When attaching your motors, you may notice that they don't roll.  This could be because the brake is engaged and or there are governors on them.  You can remove those.  We don't need safety.  

VI.  Wiring up the batteries and motor driver

Be careful in this stage.  You are dealing with 24v of power which is enough to destroy all of your precious electronics or cause you great physical discomfort.  

1. To get more power, you are going to wire the batteries in series so connect one of the batteries + to the other battery's -.  

2. If you are using the Sabertooth motor driver, you will wire it as follows:

M1A- red wire of right motor (if facing from the back)

M1B- black wire of right motor

B+ - positive terminal of battery

B- - negative terminal of battery

M2A- black wire of left motor 

M2B- red wire of left motor

On the Sabertooth motor driver, you will have to set the dip switches for type of input you are going to give it.  We are using the rc mode so set the switches as follows:

1-down

2-up

3-up

4-down

5-up

Wiring Up the Batteries and Motor Driver

Next, let's wire up the arduino and rc receiver.   I have changed the way I do this from the way it was built originally.  To improve reliability and reduce complexity, the motor driver now gets it's signal directly from the RC receiver once it goes through the 2 relays controlled by the arduino, which is always looking for a good signal.  The arduino and raspberry pi are powered off of a disassembled car cigarette lighter usb charger which takes the 12v of the batteries down to a clean 5v.  I originally had it powered off of the sabertooth but have better reliability this way.  There are many ways to kill the motors.  You can turn the remote off, push the trainer button, left with the right joystick,  or push a button separate key fob and all of these will kill it.  The Raspberry pi is only currently being used for webcam streaming.   There will be more information on which pins are being used on the arduino in the code.

VII.  The Code

It is suggested that you test out the code before you wire to the motor driver.  Even after you have tested the code, it is highly suggested that you put your mower up on blocks so that it doesn't run away from you.  This is important for you and your property's safety.  The code is available here.  Standard beer-ware terms apply.  

I hope this is helpful for anyone wanting to make a remote controlled lawnmower.  If you make one, please send us a picture and we'll post it here.
