First Part: iDraw VS iAuto, Which One Should I Pick Up?

iAuto automatic writing machine is the most advanced writing machine released by UUNA TEK in the end of 2023, the most distiguished feature is the bulk writing capacity, which can be highly much time-saving and money-saving for business, event planners, marketing agencies and non-profit organizations. 

iDraw pen plotters is also the best tool to write for you, which is the best-seller before iAuto is released. The thing is it takes longer time to switch between different papers/envelops/letters/cards than iAuto. However, it's the best option for small businesses, DIYers to make cutomized cards/invitations/letters in some special occassions.

Therefore, here are the suggestions for you to pick up between iAuto and iDraw:

1. if you have long-term requirements to write in bulk, like you're an online shop to provide writing service like Handwrytten, iAuto is the best option for you. If you just need the machine to write for you for some special occasions like the baby shower invitation writing, you can consider the iDraw machines.

2. if you have more than 100 writing tasks daily or 500 weekly, iAuto is the best option for you. Otherwise, you can choose iDraw machines.

3. if your budget is less than 1000 usd, go for any iDraw machines you like, iDraw H A3 size pen plotter is the most welcomed, both quality and performance are the best than other versions. Otherwise, go for iAuto without any doubt.

4. if your main application is for writing, both iDraw and iAuto are available for you. But if it's for drawing like digital arts or generative arts, only iDraw can be available for you. 

Second Part: How to Pick Up the Right Laser Heads?

laser heads

As the creasing demand of laser engraving heads, we updated the buying guide for those different laser power heads at the beginning for your reference.

Choosing the right laser power can not only improve the efficiency and quality of engraving but also ensure operational safety. When purchasing a laser engraving machine, it mainly depends on the material to be engraved, while considering your own needs and budget.

The laser module of a small engraving machine generally has a power range of 0-15W, mainly used for surface engraving and cutting of materials such as paper, thin plastic, thin wood, leather, and metal (with surface coatings). The following materials cannot be engraved: metals (regardless of thickness), stone, ceramics, gemstones, reflective materials, transparent glass, ivory, colorless transparent materials, some white plastics, etc. (generally very smooth plastics are difficult to engrave).

UUNA TEK® Pen Plotter offers the following laser modules: 0.5W, 1.6W, 2.5W, 15W. Materials that can generally be engraved include: light wood, kraft paper, fabric, leather, some plastics, wood, bamboo, opaque acrylic, etc. If for cutting purposes, it is recommended to use 2.5W and 15W lasers for faster speed and better quality, but ensure the safety of use.

For different materials, you can refer to the following table for specifics:
