One great reason to give the PLA a break would be the immense amount of detail builds possess when printed by a photocuring resin 3D printer like the No products found.. Even if this is your first step into 3D printing, a resin printer yields precise builds with a smooth finish not so easily garnered when printing with filaments with less post-build processing. 

Here’s the breakdown of the specs:

Design & Features of the Hieha SQ1 3D Printer

The industrial look of the HiEHA SQ1 3D printer proves to be one of structural integrity with its all-aluminum body and an ultraviolet acrylic cover to sustain builds during the curing process. When it comes to curing, the SQ1 uses a funnel type UV light source for a fast build speed of up to 40 mm per hour.  

The LED light source passes through an LCD masking screen with a 2560 x 1440 (2k) resolution. Once the design is loaded from the ChiTu Box slicer software, prints can be loaded onto the printer through the USB drive, ethernet cable, or over Wi-Fi. After selecting your design file and filling the vat with resin, the bed needs to be leveled. This is done automatically through the 3.5-inch smart touchscreen. Navigating the high-resolution color display raises the platform along the z-axis rails the moment the SQ1 is turned on.  

The ChiTu Box and NanoDLP system are preinstalled to assist the function of the printer. The company insists on not upgrading or doing a factory reset to prevent operational issues. Another feature is the resume print function that allows for prints to be paused for a number of reasons like a power outage, resin spill or refill, a botched design file, or to simply pause the build. Let’s get into how the HiEHA SQ1 resin 3D printer prints. 

Printing   

This No products found. review found the printing process to be stable and quiet mainly due to the Dual Taiwanese HINWIN z-axis linear guide rails. These guide rails move the print bed out of the vat while each layer of the design cures. Since the z-axis is the only part moving throughout the print process, it decreases the amount of noise and vibrations significantly. 

The HiEHA SQ1 uses direct UV light printing technology to print layers as thin as 20 microns to yield finely detailed builds. The LED light is focused directly on the pixels of each layer to cure them at the recommended speed of 30 mm per hour. Of course, layer height and build speed changes depending on the kind of resin used.  

This HiEHA resin 3D printer can print with non-proprietary as well as those sold by the company. When working with photocuring resin, be sure to wear gloves while handling the resins and the resulting build. Add drain holes to your design files so the excess resin can exit the builds. After the print job is complete, use the included scraper to remove it from the build plate. Rinse the build in an alcohol solution and, if necessary, allow it to cure for additional time according to the resin’s specific properties with a UV lamp. 

Working with different resins can be difficult, but the HiEHA SQ1 3D printer provides an onboard slicing software where specific resin profiles can be dialed in to achieve amazing results. The 3.5-inch touchscreen lets users navigate these settings along with viewing usage during a print job. The usage feature monitors how much resin is being used, how many layers have been printed, and how much time is left.  

The company markets the HiEHA SQ1 resin 3D printer as ready to go within five minutes of powering it on. There’s a test print preloaded onto the included USB drive along with the printer’s user manual. Let’s take a look at what’s included. 

Packing  

Unpacking the HiEHA is easy enough. It’s packed tight with foam inserts to minimize the chances of damage during shipping. There isn’t any real assembly required outside of connecting the power cord and plugging it in.

Customer Support  

While HiEHA is still a fairly new 3D printing company, most customers report quick response times when reaching out to technical support. The main mode of communication is through email, and responses can be expected within a day or two. Should you run into any issues, you can also find the company’s social media pages and groups to troubleshoot any hiccups. 

The after-sales team and technical support are available 24 hours daily. They can assist users in replacing the printer if necessary and covered un the warranty. HiEHA offers a 3-year limited warranty, but the FEP film and 3.5-inch smart touchscreen display aren’t covered. 

Hieha SQ1 Pros & Cons  

No products found.

No products found.

Pros

  • Builds are produced with exceptional quality and details 
  • Dual Taiwanese HINWIN z-axis linear guide rails help keep the printer quiet during the build and speed up the cure times per layer 
  • The printer’s touchscreen display and functions are easy to navigate and use 
  • No assembly required make the printer easy to set up and ready to use out of the box 
  • Build designs can be sent through an ethernet connection, over Wi-Fi, through the USB drive, or from the onboard slicer 
  • Resume print function allows for resins to be changed in the middle of a print job 

Cons

  • Like most resin 3D printers, the build area is fairly small at 4.53 in x 2.56 in x 3.94 in 
  • While resins can be switched in the middle of the print, doing so may cause the build to fail as varying resins require different settings for their particular chemical makeup 
  • Working with resin 3D printing can get messy  
  • Resin isn’t included with the purchase of the printer 
  • HiEHA’s website is difficult to navigate when searching specifically for the SQ1 

Verdict  

This No products found. review finds that the resin 3D printer is worth it, even without an included sample of resin. It’s an affordable resin printer well suited for dental offices, jewelry-making studios, and companies in need of printing parts or prototypes. Even the most novice of enthusiasts will find this printer easy to use. Its 3.5-inch touchscreen menu grants access to features that set the HiEHA SQ1 apart from other resin printers. Being able to monitor how much resin is being used, along with how much print time remains, lets users manage the time dedicated to the build. 

In addition to that, the resume print feature is resourceful, and so is the ability to print offline. The printer’s ability to function without a Wi-Fi connection or having to be directly connected to a computer makes it a great machine to have in an office setting. It prints quietly and also has a mobile phone app that allows connectivity to view the build progress and control functions. The 8 GB onboard storage gives users plenty of room to upload designs or build from the preloaded files.
