Editor rating

Brother DZ3400 belongs to the Designio series of sewing machines rolled out by Brother. Designio series primarily targets designers who are always on the lookout for that perfect finish. At the time of writing this review, a total of 6 sewing machines belong to the Designio category and 4 of them are regular computerized sewing machines. Apart from the DZ3400, other 3 machines look very similar from the outside (DZ3400 has a different color compared to other 3). 

4 Designio sewing machines differ in the number of built-in stitches, size of the LCD screen, specialty feet that comes with them and also in the number of built-in lettering fonts. The machine on our hands, the DZ3400 is a step ahead of the other 3 machines in terms of built-in sewing stitches.

Now let us have a closer look at Brother DZ3400. The machine comes with a total of 270 built-in stitches which include 160 sewing stitches and 110 alphanumeric stitches. It has 2 lettering fonts for basic monogramming. This might be a very important feature for some. Brother had to include sewing lettering fonts, as this machine primarily targets sewers who do a lot of creative work. It also comes with 8 fully automatic 1-step buttonholes that will automatically fit your buttons. DZ3400 has a larger LCD display when compared to DZ2400, which makes stitch selection and adjustments very easy.

Brother DZ3400 comes with sewing start/stop button and speed control slider. This feature lets you sew without using the foot pedal, you can control the sewing speed with the speed control slider. You can go really slow at snail speed if you want to. The motor is powerful enough to go really fast as well. The motor can deliver a maximum of 850 stitches/min. The bobbin is top drop-in type, so you don't need to remove the storage compartment attachment to load the bobbin. You will also get a clear view of the bobbin thread supply, thanks to the clear cover.

The sewing space measures 5.7" x 3.8". The large sewing space is one of the main highlights of Designio series machines. To add to that, you will also get a wide extension table to accommodate large projects like quilts. Space wise, DZ3400 is more than enough for me as a designer. The work area is well lit by stay bright LED. The automatic needle threader adds to the ease of use. It also features programmable needle up/down which is vital for quilters. An easy reverse sewing button is also provided.

The maximum stitch width that can be set is 7mm and stitch length is 5mm. Another highlight of Brother DZ3400 is the accessory package that comes with it. The whole package has a lot of value. It includes a lot of useful accessories like 14 sewing feet which also includes a circular sewing attachment with which you can make precise circles. The 7 point feed dogs ensure consistent fabric movement. You can also do free-motion quilting on this machine.

A manual thread cutter is provided on the side of the machine to cut threads without reaching out for scissors. Even though Brother DZ3400 is loaded with features, it still is one of the lightest machines around. It just weighs 9.9 lbs. It comes with a carry handle as well. The machine comes with 25 year limited warranty cover.

Ease of Use

The user manual is very well detailed, so you won't have any trouble setting up. You can't really complain about the quality of Brother DZ3400. One thing I have noticed is that, all Designio machines have excellent stitch quality irrespective of the type of fabric used. It is even more apparent while using thick fabrics like denim. Throw 4 or 6 layers of denim at the this machine and it will sew through beautifully. There is no stalling or slowing down, the motor is powerful enough to handle multiple layers of fabric without any difficulty. The LCD display is very user-friendly and it displays the selected stitch, stitch width and length, recommended presser foot etc. It has a good variety of stitches to choose from, which is very important for a creative person. The monogram fonts though small in size for my liking, come out well and are consistent.


No option to adjust the presser foot pressure.

Review Verdict

Brother DZ3400 covers all the aspects. It is feature packed, it has good stitch quality and it comes with a very impressive list of included accessories. I really love the accessory package that includes 14 feet, extra wide table and hard cover. The accessory package itself is of great value.
