Choosing Your First 3D Printer

About once a month, a friend requests my expertise in helping them select a 3d printer. First question is usually; "How much does a good one cost?"

So what is a good 3d printer? One that spits out a molten line of plastic while the stepper motors move the plate and extruder to create some shape that resembles your .STL file to the most accurate resolution without defects, in a timely manner. Wait, what?

The first thing you need to ask yourself is; "How much patience do I have and how much time do I want to spend failing learning?"

The real question you need to ask yourself is; "How much am I willing to spend on something that realistically will print one or two useful things but will mostly be used to print Yoda heads, baby Groot and fidget spinners."

If you have a few thousand dollars to spend and want minimal frustration, stop reading this article right now and buy yourself an Ultimaker 3. This printer is sleek and ready to go out of the box with a learning curve that will have you printing high quality parts within hours of plugging it in.


Let's say maybe you don't have $3,500 to spend, and you have more like $700 or even $300. Where do you begin?

For $300 you can buy a Prusa i3 clone or take a chance on a kickstarter campaign. The quality of the i3 clone will be proportionate to your levels of frustration  patience required. I have tried the following clone: Wanhao Duplicator i3 V2, Monoprice MK2, Anet A6. The Anet was a piece of crap. Don't get it. The Monoprice was much better, but the Wanhao Di3 takes the cheese for best cheap printer.
So there you go for cheap. I recommend packaging one of those printers with either yoga classes, anger management classes or a book on patience. It is a great printer and you will learn how to search the internet to find out why your prints aren't working. Then you will learn how to make awesome prints after nearly burning the house down and wasting half a roll or filament.

So let's move on to a higher price bracket, mid range but still cheap 3d printers. The Prusa i3 is the industry standard, and is so popular that it is back ordered for months. Most people would still recommend the Prusa i3 original on this one, but I'm looking at a high quality Made-In-USA clone. The Pulse is instead of stripped down like most clones, stripped up. I was given a demonstration at Matter Hackers in Orange County, CA. The printer is silent compared to the racket Wanhao that kept my roommates up at night. It has auto bed leveling and comes out of the box already calibrated and ready to print. The printer starts at $599 and can be customized with upgrades if needed. If you just want to print with PLA and call it a day, stick with stock and maybe just the LCD screen/ SD card slot. If you want to print with more advanced materials, go ahead and get the heat bed as well as E3D hotend upgrade.
 
So let's say you are buying a 3d printer for your business or you just happen to have extra money to spend on 3d printers, what would a good 3d printer be? Stay tuned for my next blog about industrial 3d printing. 

Mobile 3D Printing

This article is purely for entertainment, Please do not print in a way that it would distract you from driving.

Okay I'm going to tell you guys a little bit about 3D printing while driving. Mobile 3D printing has given me the opportunity to visit businesses and demonstrate 3D printing on the road. It has allowed me to harness my creative energy while on vacation and on travel. I have been able to print in some of the most remote places across the United States of America. I have been allowed to be mobile and fluid with my business.

I am using an Ultimaker Extended 2+. The materials I have used to print so far have been TPU and PLA.I recommend buckling up the printer in a backseat or having the printers safely nestled in the rear compartment of your vehicle. As of this article being written there are no restrictions that I have found anywhere in the world that I know of that make 3D printing illegal while driving. However it is illegal to use handheld electronic devices. It is also illegal to do things that distract you from the road in many places such as reading a book while driving or eating while driving. Please follow all traffic rules laws and regulations while driving. I am not responsible for any damage to your car 3D printer or any other repercussions from printing in a vehicle.

I recommend using a power source and inverter that is a system separate from your vehicle. As of now I am using a small 12V DC AC power inverter that plugs into my cigarette lighter. Also please keep in mind that you are in a small confined space and printing with toxic materials can be dangerous. Even while printing with PLA or PETG you should use proper ventilation.

The first part that I printed was the state of Montana, while driving across the state! I used TPU on a clean glass build plate with no heat heated build plate. The hot end and the build plate were just too much for my cars power source to handle. When you print in the movie Vehicle you need to go much slower any bumps breaking turns and other vibrations can cause defects in your prints. As I was driving through Montana I was going on a smooth Highway and maintaining a constant speed of 79 miles per hour. I started the print on the side of a back road in a safe location. I slowly accelerated onto the freeway as to not disrupt the print with any hard acceleration jerking movements. The results off of my Ultimaker were a clean 3D printed part of similar quality that I have gotten on a desktop. One of the benefits of having such a rigid structurally sound 3D printer is that environmental vibrations have little effect on the print. The components are in static relationship to each other.


Let’s talk about costs. So you might say that 3D printing is inefficient from a car. While the car was idling, the printer utilized about one gallon of gas per 2 hours. While driving I did not notice much of a decrease in fuel efficiency. I did notice that while driving in a city environment with lots of stops and turns that I accelerated much smoother than I drive on a regular basis. So my fuel efficiency in the city was actually slightly better than if I were to be just driving. So actually I’m becoming a better driver and being more fuel efficient due to the precious cargo on board.

Mobile 3D printing has allowed me to bring creation into my mobile lifestyle. It has allowed me to incorporate my hobby into my other hobby; adventuring. I have been able to reach businesses and customers that have never even heard of 3d printing in their small town. I'm going to continue 3D printing on the road and continue my adventures around the states. I hope to expand my adventurous business from a small SUV to an RV. From this mobile Makerspace, I would be able to share my passion at art festivals, maker faires and would have the capacity to support disaster relief and power plant outages with on-site design and manufacturing.

Part 2: 3d printing at a regional burn

Two years after writing part one, I have travelled through 17 states and lived almost two entire lives; one in North Carolina and one in Japan. I won’t get too into the sequentially boring thousands of miles of road. I will tell you about when I went To The Moon (a regional Burning Man event)  and 3d printed out of the back of my spaceship (Mazda CX-5.)

Okay. So. There I was in a field.

I wanted to make friends. I wanted to share smiles and make other people happy. I wanted to show the world something new. Something only I do. I wanted to make really cool wearable stuff. I wanted to give to others. The resultant was me making translucent masks and finishing a Daft Punk replica helmet. I had a 3d printer. I had filament. I had a power inverter in the back of my car. Same setup as part 1.

Here’s what I made:

Instagram Post after To The Moon

Cool? Yes. I made this with a 3d printer, a hot glue gun and some LED electronics bought online, all out of the back of my car. I even made an extra one to gift! Three hour print. I spent the entire day trying to get it right! At night time, I suited up, grabbed my rope dart, and spun fire dart as Scorpion from Mortal Kombat! It was fun but I didn’t feel like too many people enjoyed it. They were scared of me and the mask! I guess art doesn’t always inflict an emotion that brings joy. It can bring fear. So who know, I met one person got super stoked about it. Then I got stoked about 3d printing. I told him about my light up Daft Punk helmet and he got even more excited! He invited me to come by his camp where they were hardcore Daft Punk fans! Woo!

So this is where the night becomes very fast. When you are in the flow, or the “zone” then time does funny things. I am completely sober at this point in my life. While running back to the car, people are getting lit on the vibe of the night. The energy is building all over the farm. You can feel the electricity in the air. I’m super happy and I’m running to my car. I grab the helmet and put some last minute touches with duct tape. I head back towards the Daft Punk fan camp wearing my Guy Manuel helmet.

Piece One of Eight

I get to the camp and the DJ is blasting some eye punk rock technological disco EDM. I pull out an LED rope dart and danced. The whole camp gets up and starts jumping and prancing and dancing with me. We are instantly a group of friends. I go to the DJ and ask if he wants me to play “my music.” He says
“You have no idea how much that would mean to us!”
“One More Time” drops on the second deck on the screen of this laptop. I play with the filers, chop and screw the track to make it sound something new. As soon as I fade out the song the previous DJ was playing, I load “Harder, Better, Faster, Stronger.” Like I said before, I am in the freaking zone and in the zone time does funny things! I don’t remember much after that but fun is fun. Playing music while pretending to be some silly DJ is fun!

What a night! I love being able to get creative and vibe with other people. Social interaction without alcohol after using alcohol as a crutch for so long, can be tense. Once you break free through the barriers of tension, you can flow freely and be in a smooth state of mind. That state of mind is known as the flow, but really it’s just an actualized state of being where you can be yourself! When you are being yourself, you are in the flow! You’re not worried about threats. You don’t care what people think about you. You don’t make mistakes because you already set up boundaries and have surrounded yourself with people that respect your boundaries.

I cannot stress how important it is to surround yourself with people who respect your boundaries. People with ulterior motives of greed and lust won’t let you be you! People who enjoy accepting what others have to offer and are always seeking to offer what they have to offer without expecting anything in return are so good to be around!
