Sovol SV01 Review – A 3D Printer that Prints like a Boss

Howdy, Karl here. Let’s do this backward today and give final thoughts first …I like the SV01 3D printer. With a print volume of 280x240x300mm, it’s a good size printer. I think I could get several more centimeters in height if I relocated the filament sensor. I have had it for several months and have printed with it quite a bit and had a really good experience. It is a keeper. By that I mean I have reviewed quite a few printers and I don’t have enough space to keep them all. I find the less desirable ones good homes with friends and family. BTW I plan on doing a follow up soon for all the past articles. Just a few highlights per past article. I think it would be interesting. It is hard to truly review some products in a short amount of time. Back to the SV01…IMO, likes […]

How to Easily Calibrate Retraction in 3D Printers

[Update July 2020: It is now recommended to use Calibration Generator program instead of the Google Doc Spreadsheet in this article] Hey, Karl here with a short article on retraction tuning. I really enjoy reviewing 3D printers and all things 3D printing with one exception…. when I have to calibrate retraction (aka retraction tuning). It takes so much time. What is Retraction? While 3D printing on a standard FDM printer, the filament is pushed with an extruder motor that has a gear attached. It pushes the filament, either directly into the hotend assembly or through a Bowden tube to the hotend. Molten plastic is then layered to produce a model. When it is printing nearly all prints require non-extruding movements. During the extruding moves pressure builds up and in order to stop stringing and blobbing during non-printing moves, a retraction happens. There are 2 main variables that affect this: the […]

Open Source ESP32 3D Printer Board Supports Marlin 2.0 Firmware

Espressif ESP32 processor was initially designed for cost-sensitive IoT projects thanks to its built-in WiFi & Bluetooth connectivity and low price, but the WiSoC’s fairly powerful two Xtensa cores found other uses such as face detection and audio applications among others. But a few people are now collaborating to bring ESP32 to the world of 3D printers with an open source hardware RepRap 3D printer controller board that has beta support in Marlin 2.0 RC1 firmware. There’s no commercially available ESP32 3D printer controller board right now, so only prototypes from the community are available. There are mainly two version of the boards: R1 and R2 designed by Simon Jouet, and at least one member – Felixstorm – made his own R2 board from the MIT licensed KiCad based design. R2 is a better design leveraging ESP32’s I2S interface to have more output pins and improve stepping. Felixstorm connected the […]

Snapmaker 2.0 is a 3-in-1 3D Printer, CNC and Laser Engraver (Crowdfunding)

The Snapmaker 2.0 is going to hit the market very soon, and it comes with a modular design and functionality to rival the high-priced all-in-one 3D printers, but comes at a very reduced price point. The company was featured on KickStarter and was fully funded within just a few days. Snapmaker 2.0 has many features and upgrades from the earlier model. The Snapmaker 2.0 comes in 3 models, the A150, A250 and the A350 and the main differences are in the build scalability. Respectively the build volumes range from 164x160x160mm which at the smallest range, it is already larger than the original Snapmaker, up to 320x350x330mm. These 3D printer models will carry a different pricing structure, but still in the modest range for a 3-in-1 3D printer with the A150 at $719, the A250 at $899 and the A350 at $1079, for preorder on Kickstarter. The Kickstarter price is […]

TH3D EZBoard Lite Board Upgrades Ender and Creality CR-10 3D Printers

The basic setup of Creality 3D’s very popular Ender and CR-10 series 3D printers now have a drop-in board upgrade that is poised to rival printers that cost many times more than the Creality models. The original board only utilizes the ATmega2560 microcontroller, the A4988 stepper motor drives, with those cheap Chinese capacitors. The board runs Marlin 1.x open source firmware. This setup is very close to the Arduino Mega 2560 and the RepRap RAMPS 1.4 board which are some of the most common and simplest board combinations in the world. The upgrade from TH3D, is the EZBoard Lite, makes some very important changes to the overall board ability, scalability and functionality. The physical process of upgrade is simple and easy. The outcome is an increase in speed and functionality that is comparable to 3D printers costing 5 to 10 times as much. Features Easy Drop-In Installation No Soldering No […]

Review of Zonestar Z6 Low-cost 3D Printer

Ugh…I don’t like calling these reviews. I like to say that I am sharing my experiences with the products. I have a fair bit of experience under my belt using 3D printers now but still don’t consider myself an “expert”. I think that I have had about a dozen come through here. Anyway on with the show. Today we are going to look at a very economical 3D printer: the Zonestar Z6. I have to say I wasn’t expecting much. I read/ watch a lot of reviews about 3D printers and sub $100 printers aren’t typically very good. Gearbest recently had the Zonestar Z6 on sale for $99 that Jean-Luc recently posted here on CNX Software but is currently $120. Let’s see how it prints. Some assembly required I designed a spool holder but not very good. The whole printer rocks when the full spool is on it. The tiny […]

Alfawise W10 is a $300 Resin (SLA) 3D Printer

Most 3D printers on the market work with filaments using fused deposition modeling (FDM) technology, but in the past we’ve also seen 3D printers using resin and stereolithography apparatus (SLA) technology. The latter is supposed to enable more detailed, yet faster prints, but storing and keeping the liquid resin is a bit more challenging than simply handling filament. In the past I had come across two resin 3D printers in the news, namely the infamous Peachy printer, and the $99 ONO 3D printer working with a smartphone, which was introduced in 2016, but the company is still working on the printer, and most backers have not received their rewards. But today, I’ve come across another resin 3D printer with Alfawise W10 that’s available for $299.99 plus a few dollars for shipping. Alfawise W10 key features & specifications: Display – 2.5″ full color LCD display Storage – microSD card slot Build […]
